APM Oauth clintless mode
Hi, We currently have the following setup: client( not a web browser) sends a post request to an internal oauth server with the following parameters: username: some_user password: some_pass scope: some_scope grant_type: some_grant if the client passes the authentication he receives a bearer access token which is inserted to the header on the response. Then he can access and use the rest api. We want to integrate F5 into the current scenario so it will act as a client/resource provider( I hope those are the right terms) and then will check the validity of the access token. I'm pretty new to all of the terms and the process of getting an access token, I have read couple of posts on devcentral, guides on f5 clouddocs and on ask f5 and started to play around with it. Those are the resources I've used so far: https://devcentral.f5.com/questions/apm-authentication-for-a-sessionless-and-clientless-api-62162 https://clouddocs.f5.com/training/community/iam/html/class2/module1/module1.html https://support.f5.com/kb/en-us/products/big-ip_apm/manuals/product/big-ip-access-policy-manager-single-sign-on-concepts-configuration-14-1-0/04.html https://support.f5.com/kb/en-us/products/big-ip_apm/manuals/product/big-ip-access-policy-manager-authentication-and-single-sign-on-14-0-0/38.html I have a very general idea how its supposed to work: Client sends a POST request to a VS with apm. An irule will check the request and insert clientless mode. somehow I need to parse the POST parameters and assign them to the appropriate APM variables. There must be a provider configuration and a request configuration ( with the appropriate variables which were parsed ). F5 requests an access token from the oauth server and if successful then on the response it inserts a bearer header with the received access token. The client sends requests to the api which is configured behind a different VS with a per request AP which will verify his bearer token and the scope with the Oauth server. I would like to know if that's something possible to achieve and where and how to start. Thanks, AlexOAuth 2.0 Dynamic Client Registration
Problem this snippet solves: OAuth 2.0 is now supported in version 13. Client applications need to be defined manually in the Web UI. We developed an irule allowing a client application to self register. How to use this snippet: This code makes calls to external functions : json2dict and HTTP Super SIDEBAND Requestor.

Federation SP SAML with connector automation, Azure as Idp
Hello, I'm tring to setup connector automation for a customer where the BigIP is the SAML SP provider, and Azure as Idp. all is fine, everything is created and authentication is working. However after every "Frequency", the checksum is different and External IdP Connector is being recreated. And therefore the Access Policy needs to be applied. When the Azure, App Federation Metadata file, is download by a browser, the file is never the same. The "EntityDescriptor ID" changes with every download. And therefore also the checksum. So is the IdP Connector automation an option when Azure is IdP? Am I doing something wrong? I've tested with 15.1 and 16.1, but no different behaviour Thanks in advancetcl logic in SAML Attribute value field possible?
Hi. We're running BigIP as a SAML IDP. Can I somehow issue tcl logic in a SAML attributes? I'm talking about the Access ›› Federation : SAML Identity Provider : Local IdP Services, editing an object, under SAML Attributes. Based on what's in the memberOf attribute, I need to issue as a value either empty string or "SpecificValue". I am familiar with the %{session.variable} construct, but I don't want to clutter the session with more variables if I can avoid it, as that impacts all sessions using our IDP (30 or so federated services on the same VIP and AP). I tried these two approches: %{ set result {} ; if { [mcget {session.ad.last.attr.memberOf}] contains {| CN=SpecificGroup,OU=Resource groups,OU=Groups,DC=Domain,DC=com |}} { set result {SpecificValue} } ; return $result } expr { set result {} ; if { [mcget {session.ad.last.attr.memberOf}] contains {| CN=SpecificGroup,OU=Resource groups,OU=Groups,DC=Domain,DC=com |}} { set result {SpecificValue} } ; return $result } Expected result: An issued claim with the value "" or "SpecificValue" Actual result: An issued claim with the above code as the value As I mentioned, we've set it up using one VIP that is hosting 30 or so services. We're running 16.1.3.1. They are using the same SSO configuration and there's an iRule triggerd at ACCESS_POLICY_AGENT_EVENT, which does some magic to extract issuer and suchlike, and that helps to make decisions later in the Access Policy. It also populates a few session variables under the session.custom namespace for use in the Access Policy. Additional session variables are being populated in the Access Policy, such as resolved manager and their email address. I have looked briefly at the ASSERT::saml functions, but even if it would bepossible to manipulate that way, I wish to keep this set up as stream lined as possible and with as few new "special cases" in an iRule. So while I appreciate pointers along that route as well, I would first of all like to know if there is a way to do it natively in the SAML attribute value field. And if there are any options I have not yet explored here?
Evaluating common integrations between Azure AD and APM - Part 1
Identity as a Service providers (IDaaS) are exploding in adoption rate, Azure AD being one that I encounter most frequently. Given that, I am often asked what options are available for integration between Azure AD and BIG-IP APM, including implementation steps. In this 4-part series, I will first summarize and contrast the integration options, including the pros and cons of each, then in each subsequent article we will dive into the requirements and implementation details for each method of integration. Please note that there may be additional integrations and authentication flows, this article series is however only covering 3 in particular. The 3 authentication flows we will discuss in this article series are: Network Policy Server (NPS) Azure MFA extension** SAML federation ROPC Oauth grant authentication flow **This replaces the legacy integration with Azure MFA Server which is no longer supported: https://devcentral.f5.com/s/articles/heres-how-i-did-it-integrating-azure-mfa-with-the-big-ip-19634 Method 1: Azure NPS Extension The method we will be examining in the first article of this series is integration between BIG-IP APM and Azure AD via a Network Policy Server (NPS) extension. This method is used to achieve Azure AD Multi-factor Authentication (MFA) capabilities for user authentication which is most often the primary business requirement for integration. User authentication requests are sent from BIG-IP APM to the NPS server where the NPS extension for Azure MFA will then inform Azure AD to initiate the MFA challenge. The NPS extension for Azure MFA does NOT support any conditional access policies, as the source of every authentication request from Azure AD's perspective will be that of the NPS server itself.By using this method, we can capture the username and password on the APM logon page for seamless password-based Single Sign-On (SSO), plus we get the MFA capabilities of Azure AD, truly the best of both worlds. Architecture and authentication flow: User requests a resource protected by BIG-IP APM and is presented with an APM logon page where they enter their credentials. BIG-IP captures these credentials as session variables and sends them to the predefined RADIUS AAA server, in this case that would be the NPS server with Azure MFA extension. The RADIUS server first validates user credentials, if successful then the 'AzureMFA' extension will notify Azure AD of the incoming user authentication request and initiate MFA challenge. The user is challenged using the chosen MFA method. Azure AD notifies the NPS extension of the MFA challenge result. The NPS extension responds back to the BIG-IP with a RADIUS response based on the outcome of the MFA challenge. If successful, the user is granted access to the protected application, webtop or resource. Pros: BIG-IP APM can capture both the username and password as session variables as part of the logon process, making password-based Single Sign-on (SSO) viable Requires no federation between BIG-IP and Azure AD Cons: Requires external infrastructure dependencies (Redundant NPS infrastructure) Azure AD Conditional access policy support is limited ***This however can be augmented with conditional policies on BIG-IP APM Method 2: SAML federation with Azure AD SAML is a well understood and adopted standard for federation between identity domains. By federating BIG-IP APM with Azure AD as the Identity Provider (IDP) we direct all user authentication requests to Azure AD. This means that all authentication features supported by Azure AD, such as Conditional Access Policies and MFA will work as intended, as the user is interfacing directly with Azure AD during authentication. By its very design, SAML federation limits the SAML Service Provider (SP), which is the role of BIG-IP APM in this case, from receiving the user's password as part of the authentication flow; this means we must use passwordless Single Sign-On (SSO) methods such as Kerberos or SAML for seamless access to applications and resources. Architecture and authentication flow: **Above depicts SP-initiated SAML authentication flow where BIG-IP APM is the Service Provider (SP) and Azure AD is the (IDP) User requests a resource protected by BIG-IP APM. APM responds to the user with a SAML request and directs them to the IDP (Azure AD). The user browser relays the SAML request to Azure AD. It is at this point that the user authenticates DIRECTLY with Azure AD. Once successfully authenticated (including MFA, if applicable), Azure AD responds to the user with a SAML response containing an Assertion and directs the user back to the BIG-IP APM. The user browser relays the SAML response to the BIG-IP and is provided access to the protected application or resource. Pros: Widely deployed and understood + very easy implementation Full support for conditional access policies and authentication functionality in Azure AD Cons: BIG-IP APM will not receive a password as part of the logon process - this means that password-based Single Sign-On (SSO) will not work out of the box ***We will explore options to get around this further in Article #3 Method 3: ROPC Oauth Grant The Resource Owner Password Credentials (ROPC) grant allows an application or intermediary to sign a user in by directly handling their password. Put simply, BIG-IP APM first captures the user credentials with a standard logon page and then validates them with Azure AD directly. This authentication flow may resemble that of traditional authentication flows such as Active Directory domain controllers or RADIUS servers. In most cases, ROPC grant flows are not highly recommended, as the user credentials are provided to the Oauth 2.0 client (BIG-IP) directly instead of to the Authorization Server (Azure AD) which arguably introduces additional risk.By using this method however, we capture the username and password on the APM logon page for password-based Single Sign-On (SSO) without requiring any on-premises infrastructure such as domain controllers or AAA servers to handle authentication. Architecture and authentication flow: User requests a resource protected by BIG-IP APM and is presented with an APM logon page where credentials are input. BIG-IP captures these credentials as session variables and sends them to the predefined Oauth Authorization Server (AS), Azure AD. If the credentials are correct, Azure AD responds to the BIG-IP with an ID token, Access token and optionally a refresh token. If successful, the user is granted access to the protected application or resource. Pros: BIG-IP APM can capture both the username and password as session variables as part of the logon process, making password-based Single Sign-on (SSO) viable Requires no on-premises infrastructure such as Active Directory or RADIUS/NPS for authentication Cons: Not recommended by Microsoft for Security reasons. No direct support for Azure AD MFA No support for Azure AD conditional access policies ***This however can be augmented with conditional policies on BIG-IP APM Summary In the first article of this series we reviewed 3 unique options for integration between BIG-IP APM and Azure AD. We also described the authentication flow as well as the pros and cons for each method. In each subsequent article, we will dive deeper into these three methods, providing detailed implementation instructions, caveats, and requirements as well as some anecdotal wisdom from the field!ADFS Proxy- first time setup
Very new to ADFS and SAML especially with dealing with the F5. I have business case to add ADFS to one of my current setups. My organization has ADFS setup and i have a few questions for the community. Do i first connect and test the application with our current ADFS setup to make sure it can work? Once the ADFS has been tested and working, do i then try to do ADFS proxy withthe setup? or do i skip step 1 and just start with the ADFS proxy first and try to get that to work with the application? I have seen a few online labs for ADFs proxy etc... but just wondering what the community thinks? looking to have it setup like this: User -> F5 (VIP with login portal) -> sends info to ADFS -> ADFS sends token to F5 -> traffic goes to VPN tunnel to actual portal -> accepts the ADFS token -> User is logged into the service. trying to keep the initial traffic going down the tunnel first and getting redirected back to the F5 for authentication.VDI Gateway Federation with BIG-IP
Today let’s look at how F5 BIGIP APM can consolidate, secure and federate all the core VDI gateways technology. For instance, if an organization decides move from one VDI technology to another or if you’re consolidating VDI technologies, BIG-IP can help. On the BIG-IP we’ve set up three VDI environments. Microsoft RDS/RDP with a broker authentication server, VMware Horizon and Citrix XenApp. With only a corporate account, a user can authenticate to all of them as needed and access all available desktop content. In this example, we connect to the BIG-IP APM. This is the default view. And here we’ve put some advanced security fields like OTP or multifactor authentication for instance. So here we’d use our username and password and for additional security we'll choose a secondary grid. By default, a grid is not generally available from any of the VDI vendors. When we select grid, BIG-IP APM will present a grid for a PIN entry. This is provided through a partnership with Gemalto. BIG-IP is connecting to Gemalto servers to present the grid to the user. We then enter our confidential PIN. Upon auth, we’re presented with our BIG-IP APM Webtop and BIG-IP did the necessary single sign on for all the VDI technologies and environments assigned to us. With a single, multifactor authentication we’re able to gain access to our federated BIG-IP Webtop and select the specific VDI resource we need. From an administrative view, here is the full Visual Policy Editor (VPE) for the overall solution. This also shows where the OTP/Grid is if you follow the Host FQDN path. And here are the specific inspections and criteria for the VDI scenario. You can see a path for each VDI vendor along with specific inspections and actions depending on the situation.

AutoFill username for Office 365 Federation
Hi. This is a simple question but I can't find a solution and ee are just getting started with our F5 implementation. I have deployed the office 365 federation using the f5.microsoft_office_365_idp.v1.1.0 iApp. I've got things working but when it redirects to my login page on the F5 the username field is blank, is this normal? is there any way to get the username from O365 and pre-populate that field? Thanks for any help JonEnabling SharePoint 2013 Hybrid Search with the BIG-IP
Over my past several blog posts, I’ve talked about federating our on-premise environments with Office 365. Now, that we have that handled, (it’s handled right?) let’s talk about another lesser known piece of the puzzle; hybrid SharePoint environments. With federation and SSO between on-premise applications and Office 365 provided by the BIG-IP and APM, (Access Policy Manager) users can move seamlessly between their on-premise SharePoint and SharePoint online as if they were one integrated application. Cool right? But what about when I need to search for content across environments? Funny I should ask. That’s what this post is all about. Microsoft actually has this figured out. The only piece missing is a device that can act as the reverse proxy for the on-premise environment and facilitate the secure connection between the two environments. Hmmm… What could we use? Configuring Hybrid Search for SharePoint 2013 This post covers the pieces required to use the BIG-IP as a reverse-proxy for a hybrid SharePoint search deployment. For guidance on configuring both your on-premise SharePoint 2013 and SharePoint Online environments refer to the Hybrid for SharePoint 2013 guidance provided by Microsoft. It’s quite thorough and, to be honest a little daunting. Currently, Microsoft’s SharePoint 2013 hybrid capabilities are intended to let users in Office 365 access and search across certain content from an on premises SharePoint farm. For detailed information on architectural recommendations and limitations take a look at the blog post from Microsoft architect, Steve Peschka. Client Certificate authentication is utilized to allow secure access for hybrid search, (SharePoint content located both on-premise and in the cloud) from Office 365 environment. To accomplish this a target application is configured in the SharePoint Online Secure Store where a client certificate, (issued by a public root certificate authority). Figure 1 – SharePoint Online Secure Store & Target application Configuring the BIG-IP for Client Certificate Authentication The following configuration was tested by F5 in collaboration with the Office365 product team. The testing was conducted at the Microsoft Technology Center in Irvine where an environment was provided for hybrid enterprise search & LOB scenarios between O365 and on-premise SharePoint farms. We collaborated with the MTC’s expert staff and took advantage of the alliance partnership between Microsoft and F5, whose solutions were made available as part of their engagement. For the purposes of hybrid search, the BIG-IP and LTM, (Local Traffic Manager) acts as a reverse proxy providing a secure Internet facing endpoint for connections from the SharePoint Online environment. The deployment of SharePoint behind the BIG-IP can either be configured manually or via the BIG-IP iApp configuration. Once SharePoint 2013 has been successfully deployed it is simple matter of modifying the virtual server’s Client SSL Profile. Figure 2 – SharePoint 2013 On-Premise Virtual Server The SSL Profile is configured to require a client certificate for successful access. Additionally, the certificate must be issued from the specified certificate authority whose CA certificate is installed on the BIG-IP. In the example below, (Figure 3) the client certificate presented must be issued by StartCom, Ltd. Figure 3 – Client SSL Profile with Client Authentication Required As long as the certificate installed and configured in the SharePoint Online Secure Store is valid and issued by the appropriate certificate authority, users in O365 will be able to search for and receive results from the on-premise SharePoint environment. Enhancing Security with iRules Ok, the above configuration provides security to the hybrid connection via client certificates. However, it’s still vulnerable. As previously noted, the certificate used must be issued by a public root certificate authority. While this is good, this does not guarantee that the certificate presented is the actual certificate configured in the SharePoint Online environment. Merely, it just guarantees that the certificate was issued from the same place, (StartCom, Ltd. in our example). Fortunately, there’s an iRule for that! The iRule provided below examines the client certificate provided and ensures that the serial number of the certificate matches the SharePoint Online configured certificate. This ensures that not only is the presented certificate issued from a specific and valid certificate authority, but also ensures that the certificate itself is an exact match. Figure 4 – Granular_Cert_Verification iRule validating the Client Certificate Serial Number 1: when CLIENTSSL_CLIENTCERT { 2: 3: # Check if client provided a cert 4: if {[SSL::cert 0] eq ""}{ 5: 6: # Reset the connection 7: reject 8: 9: } else { 10: 11: #Example Subject SN: 01 ED 51 12: set subject_sn [X509::serial_number [SSL::cert 0]] 13: log "Client Certificate Received: $subject_sn" 14: #Check if the client certificate contains the correct serial number 15: if {$subject_sn contains "0c e4 11"} { 16: #Accept the client cert 17: log "Client Certificate Accepted: $subject_sn" 18: } else { 19: log "No Matching Client Certificate Was Found Using: $subject_sn" 20: reject 21: } 22: } 23: } Figure 5 – Client Certificate Subject Name Figure 6 – iRule Assigned to Virtual Server That’s It! Not too bad huh? Of course this is the easy part. We still need to ensure that we have properly configured both environments, (on-premise and Office 365) to enable the hybrid search functionality. Accomplishing that is a little more tricky, but definitely doable. Be sure to refer to the links below for information from Microsoft on how to set this up.
