SOLVED: sending IsCompliant, IsKnown and IsManaged via SAML (SSO)
Background We have an EntraID (Azure/Microsoft365) SAML based VPN using the APM module and were keen to provide a different device pool to domain devices, rather than personal devices (BYOD). We noted that, in the EntraID logs, it included elements such as whether the device IsCompliant, IsKnown and/or IsManaged: Wrong step first We followed part of the exceptionally good video from Matthieu Dierick (https://www.youtube.com/watch?v=DBA84d4VJU8) in which he explains how to configure InTune to make the IsCompliant assertion and push a certificate onto the device to identify it.. and then the BIG-IP Edge client will send that certificate back to be used via an API call against InTune (even if EntraID isn't used for your APM authentication). To get the API bit to function we needed to follow the guidance in https://my.f5.com/manage/s/article/K00943512 But we aren't that far down the route with InTune and, without pushing that certificate, we got the error "Device ID was not found in session variables" (as explained in https://my.f5.com/manage/s/article/K93969130 ) To get working: Azure steps It seems exporting these variables isn't natively available through the GUI although there were some pointers available from Azure AD - SAML - Intune - ismanaged attribute - Microsoft Q&A In short, Navigate to: https://portal.azure.com/ Microsoft EntraID Under Manage > App registrations (this will default to "owned application") choose "all applications" tab Filter by the name of your SAML configuration Manage > Manifest Take a copy of the manifest incase you want to revert (note that it won't let you save it unless it can parse the input) Find the section "optional claims" and inject the following after any groups you pass back: "optionalClaims": { "accessToken": [], "idToken": [], "saml2Token": [ { "additionalProperties": [ "on_premise_security_identifier" ], "essential": false, "name": "groups", "source": null }, { "additionalProperties": [ ], "essential": true, "name": "is_device_managed", "source": null }, { "additionalProperties": [ ], "essential": true, "name": "is_device_compliant", "source": null }, { "additionalProperties": [ ], "essential": true, "name": "is_device_known", "source": null } ] }, To get working: APM steps In the visual policy editor you can now assign variables to those claims of the form: session.logon.last.isknown = mcget {session.saml.last.attr.name.http://schemas.microsoft.com/201 4/02/devicecontext/claims/isknown} session.logon.last.iscompliant = mcget {session.saml.last.attr.name.http://schemas.microsoft.com/201 4/09/devicecontext/claims/iscompliant} session.logon.last.ismanaged = mcget {session.saml.last.attr.name.http://schemas.microsoft.com/201 2/01/devicecontext/claims/ismanaged} So you can end up with a variable assignment box that looks like: (just be careful with copy/paste that it doesn't introduce spaces in the session variables) Then you can do a new general purpose > empty box with a branch rule evaluating: expr {[mcget {session.logon.last.ismanaged}] == "true"} Optionally you can record the output of these variables by adding a logging box with the entry: username=%{session.logon.last.username}, ismanaged=%{session.logon.last.ismanaged}, iscompliant=%{session.logon.last.iscompliant}, isknown=%{session.logon.last.isknown}
F5 configured SP initiated SAML Authentication causing multiple Redirects
F5 configured (source-ip based) to talk to 2 IBM HTTP Servers and webservers are loadbalancing using Traditional loadbalancing (Round-Robin) and routing requests to 8 JVMs of a Websphere ND Cluster. 2 Applications are deployed with context root /maximo and /saml/acs on the same cluster. When SAML Authentication is triggered via F5. We have 2 scenarios to take care F5 :- HTTPSOFFLOAD is enabled with end to end validation using HTTPS only 1. https://abc.com/maximo URL loads successfully. No issues in Authentication to SAML. When loaded follows below path 1) Incognito Browser(User) requests resource from Service Provider (SP). 2) SP Redirects (with SAML Request) to Identity Provider (microsoft-entra). 3) Since it is first login, User gives the (IdP) his/her valid credentials. 4) IdP then redirects Browser (with SAML Response which includes SAML token) to the SP page. 5) User receives the landing page. THIS IS WORKING 2. https://abc.com/maximo/ui/?event=loadapp&value=asset&changetab=viewtab&uniquid=123455 1) Incognito Browser(User) requests resource from Service Provider (SP). 2) SP Redirects (with SAML Request) to Identity Provider (microsoft-entra). 3) Since it is first login, User gives the (IdP) his/her valid credentials. 4) IdP then redirects Browser (with SAML Response which includes SAML token) to the SP page. 5) Cannot find the resource and SP Redirects (with SAML Request) to Identity Provider (microsoft-entra). 6) IdP then redirects Browser (with SAML Response which includes SAML token) to the SP page. 7) Cannot find the resource and SP Redirects (with SAML Request) to Identity Provider (microsoft-entra). Keeps redirecting multiple times and Finally timeout is hit and doesnot respond at all. It keeps redirecting when long URL is challenged. Do we need to have special irules to retain JSESSIONID state or WAS - I see this is an issue with respect to Cookie persistence
SAML Attributes require String type
I am doing a SAML Integration with Tableau Server. Actually Tableau is unable to read my username attribute, because it is missing xsi:type="xs:string" https://help.tableau.com/current/server-linux/en-us/saml_requ.htm#xml_requirements Their documentation say: "You must configure the IdP to return an assertion that includes the username attribute in the saml:AttributeStatement element. The assertion’s attribute type must be xs:string (it should not be typed as xs:any)." They required this: saml:AttributeStatement> <saml:Attribute Name="username" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic"> <saml:AttributeValue xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string"> user-name </saml:AttributeValue> </saml:Attribute> </saml:AttributeStatement> </saml:Assertion> and for now F5 SAML return this: <saml2:AttributeStatement> <saml2:Attribute xmlns:saml2="urn:oasis:names:tc:SAML:2.0:assertion" Name="username" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:basic" > <saml2:AttributeValue xmlns:saml2="urn:oasis:names:tc:SAML:2.0:assertion">user-name</saml2:AttributeValue> </saml2:Attribute> </saml2:AttributeStatement> </saml2:Assertion> Another example is using OKTA as an IDP , it return this and it works: <saml2:AttributeStatement xmlns:saml2="urn:oasis:names:tc:SAML:2.0:assertion"> <saml2:Attribute Name="username" NameFormat="urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified" > <saml2:AttributeValue xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string" >user-name</saml2:AttributeValue> </saml2:Attribute> </saml2:AttributeStatement> How can I do this with F5, we are using Big-IP release 14 I need to find a way to add xsi:type="xs:string" to the username attribute. I do not see any way to do this from the SAML Attributes in Edit IDP Service Thank,
