AD FS (service provider) configuration steps:

Step 1: Adding a new claims provider trust

• Open the AD FS Management console. Navigate to AD FS → Trust Relationships → Claims Provider Trusts.

  

• Click Add Claims Provider Trust in the Actions pane. This will open the Add Claims Provider Trust Wizard. Click Start.

  

• In the Select Data Source section, choose the option Import data about the claims provider from a file and upload the metadata file downloaded in Step 11 of the ADSelfService Plus configuration steps.

  

• In the Specify Display Name section, enter the desired Display name.

  

• Complete the remaining steps in the wizard by retaining the default values for the rest of the fields.

Step 2: Adding claim rules

• Once the claims provider trust configuration is complete, the Claims Rule Editor window opens. Click Add Rule.

  

• From the Claim rule template drop-down, select the value Pass Through or Filter an Incoming Claim and click Next.

  

• In the next window, enter a Claim rule name and set any of the supported claim types as the Incoming claim type. For information regarding the supported claim types, click here. Choose the Pass through all claim values radio button. Click Finish to complete adding the claims rule.

  

Step 3: Modify existing relaying party trusts

The existing relaying party trusts need to be modified in order to map the incoming claim to an outgoing claim that will be sent to the relaying party.

• Click Relaying Party Trusts under Trust Relationships. Right-click the desired SSO applications from the list and select Edit Claim Rules. Click Add Rule.

  

  

• In the Add Transform Claim Rule Wizard, choose the option Transform an Incoming Claim from the Claim rule template drop-down and click Next.

  

• Enter “Name ID” in the Claim rule name field and set UPN as the Incoming claim type. Set Name ID as the Outgoing claim type and click OK.

  

To enable SSO for all AD FS integrated applications, repeat Step 3 for all the applications configured in AD FS.

You have now completed configuring ADSelfService Plus as the identity provider for AD FS.
