OAuth 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. You need to add them to your set of irules on the BIG-IP before configuring the client app registration service. json2dict proc json2dict JSONtext { string range [ string trim [ string trimleft [ string map {\t {} \n {} \r {} , { } : { } \[ \{ \] \}} $JSONtext ] {\uFEFF} ] ] 1 end-1 } Workflow The client application will do the following request : POST /f5-oauth2/v1/client-register HTTP/1.1 Host: oauthas.example.com User-Agent: curl/7.47.1 Accept: */* Content-Length: 29 Content-Type: application/x-www-form-urlencoded username=user&password=pwd This request can be achieved using cURL : curl -k -vvv https://oauthas.example.com/f5-oauth2/v1/client-register -d 'username=user&password=pwd' Quick notes The irule is configured to create Client Applications with Resource Owner Password Credentials Grant (ROPC) mode activated. The irule needs to be modified to activate other modes Update (2018-05-01) Add a way to configure static client_id and client_secret Update (2018-01-12) URI decode username and password parameters Update (2017-11-07) Use HTTP::collect to workaround issues with large body Update (2017-10-25) Enhance JSON result parsing and attribute retrieval Code : when RULE_INIT { ### # credentials required to access iControl REST API ### set static::adm_user "admin" set static::adm_pwd "admin" ### # settings required to authenticate the user trying to register an application ### set static::timeout 300 set static::lifetime 300 set static::access_profile "/Common/ap-ldap-auth" ### # settings required to update the APM configuration with the newly created ClientApp configuraiton ### set static::adm_partition "Common" set static::oauth_profile "my-oauth-profile" set static::scopes "myscope" ### # settings required to sync the OAuth 2.0 Authorization Server access profile ### set static::oauth_access_policy "ap-oauth-auth-server" ### # settings required to publish the client registration service ### set static::client_register_uri "/f5-oauth2/v1/client-register" set static::host "oauthas.example.com" ### # Define a static client_id and client_secret ### set static::use_static_app 1 set static::client_id "xxxxxxxxxxxxxxxxxxxxxxx" set static::client_secret "xxxxxxxxxxxxxxxxxxx" } when CLIENT_ACCEPTED { ### # When we accept a connection, create an Access session and save the session ID. ### set flow_sid [ACCESS::session create -timeout $static::timeout -lifetime $static::lifetime] } when HTTP_REQUEST { ### # initialize vars ### set username "" set password "" set name "" set client_app "" set scopes "" set client_id "" set client_secret "" set agent "" set timestamp [clock seconds] switch -glob [string tolower [HTTP::header "User-Agent"]] { "*android*" { set agent "android" } "*ios*" { set agent "ios" } default { set agent "default" } } ### # identify client registration request.
