This is quite straightforward and modern solution for adding support for centralised authentication. These are instructions for AzureAD adminstrators We usually meet together with customer organisation representatives and their identity provider administrators and settle down procedure details and requirements. Then AzureAD adminstrators need to follow steps how to integrate TDS Keycloak using OIDC as defined in this chapter.

Registering application in Azure portal

...

• Go to https://portal.azure.com/#blade/Microsoft_AAD_IAM/ActiveDirectoryMenuBlade/RegisteredApps
• Click "New registration"
• Set name "Tietoevry DevOps Space (TDS) Keycloak" or something similar
• Select who can use it, usually first option "Accounts in this organizational directory only (for example Tietoevry only - Single tenant)" is OK

• Set Redirect URI to callback URL:

  Code Block
  https://identity.core.tds.CUSTOMERX.com/auth/realms/tds/broker/main-oidc/endpoint

  
  

  Note
  It says that it is optional, but it is mandatory in our case.

  
  

• Click "Register"
• On shown overview screen you shall find and copy following values that will be needed later for setup on Keycloak side:
  • Application (client) ID
  • Directory (tenant) ID
• Following claims need to enabled:
  • sAMAccountName (onpremisessamaccountname)
  • email
  • firstname
  • lastname
• AzureAD team must run following powershell commands to properly enable "sAMAccountName" claim

  • First we add new policy for TDS Keycloak in Azure AD, for example "Tietoevry-TDS-Keycloak-Policy" in this case:

    Code Block

    New-AzureADPolicy -Definition @('{"ClaimsMappingPolicy":{"Version":1,"IncludeBasicClaimSet":"true", "ClaimsSchema": [{"Source":"user","ID":"givenname","JwtClaimType":"given_name"},{"Source":"user","ID":"surname","JwtClaimType":"family_name"},{"Source":"user","ID":"mail","JwtClaimType":"mail"},{"Source":"user","ID":"onpremisessamaccountname","JwtClaimType":"samaccountname"}]}}') -DisplayName "Tietoevry-TDS-Keycloak-Policy" -Type "ClaimsMappingPolicy"

    https://docs.microsoft.com/en-us/powershell/module/azuread/new-azureadpolicy?view=azureadps-2.0-preview

  • Obtain relevant Enterprise application ID
    • Go to Enterprise Applications https://portal.azure.com/#blade/Microsoft_AAD_IAM/StartboardApplicationsMenuBlade/AppAppsPreview/menuId/
    • Search for application with name that you registered in previous step

  • Then we link service principal policy to Enterprise application (always remember to use correct ID):

    Code Block
    Add-AzureADServicePrincipalPolicy -Id "<Enterprise-Application-UUID>" -RefObjectId "9cb83e39-8b0b-40da-8e2c-e49b8d2522b7" #'Tietoevry DevOps Space (TDS) Keycloak' & 'Tietoevry-TDS-Keycloak-Policy'

    https://docs.microsoft.com/en-us/powershell/module/azuread/add-azureadserviceprincipalpolicy?view=azureadps-2.0-preview

  • Then go to application permissions and grant "Admin" consent (on behalf of all users in this tenant) as following:

    Microsoft Graph	Claim value	Permission	Type	Granted through	Granted by
    Microsoft Graph	User.Read	Sign in and read user profile	Delegated	Admin consent	An administrator

    
    

  • Then go to "Manifest" and enable custom claims mapping as suggested in https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-claims-mapping#security-considerations 

    • Find line with "acceptMappedClaims" and change it from "null" to "true"

    • Click "Save"

...

We also need to setup process for replacing secret on regular basis according to validity possibilities.

TDS team then takes over and finishes setup according to internal documentation OpenID Connect brokering setup.
