Users may not be able to login to Microsoft Dynamics CRM using internal claims based authentication or IFD. The user will be repeatedly prompted to sign in.
In the Microsoft Dynamics CRM user interface the user will see the message below:
HTTP Error 401 - Unauthorized Access is denied.
or
An error has occurred.
The Token-signing certificate and Token-Decrypting certificate in ADFS will automatically be renewed by the Auto Certificate Rollover feature because these certificates reach their expiration date.
In ADFS Management Console update the Federation metadata URLs and do an IIS reset on CRM server. Next, restart the ADFS service.
If above steps do not resolve the issue please follow below steps:-
1. On the Microsoft Dynamics CRM server, go to Deployment Manager and disable the Claims Based Authentication
2. On the Microsoft Dynamics CRM server, click the Start menu, select Run and type iisreset to complete an IIS reset
3. Re-configure Claims-Based Authentication from Deployment Manager keeping all the settings same
4. Re-configure IFD through the Microsoft Dynamics CRM Deployment Manager
5. On the Microsoft Dynamics CRM server, click the Start menu, select Run and type iisreset to complete an IIS reset
6. In ADFS Management Console on the ADFS server, update the corresponding Federation Metadata URLs
a. Go to the ADFS Server and open the ADFS management Console
b. Click Relying Party Trusts to display the internal and external relying party trusts
c. Right-click each and select Update Federation Metadata
d. Go to the Microsoft Dynamics CRM server, click the Start menu, select Run and type iisreset to complete an IIS reset
e. Next, browse to Service on the ADFS server and restart the ADFS service
The signing certificate in ADFS (Service -> Certificates -> Token-Decryption/ Token-Signing) shows two Token-decrypting and Token-signing certificates with one Primary and one Secondary status.
There are two signing certificates. The second signing certificate was created by ADFS automatically because the first signing certificate was reaching it's expiration date. This feature in ADFS is called Auto Certificate Rollover.
In the Microsoft Dynamics CRM server database, it still has the old certificate entry, which causes the authentication to fail. The issue will be resolved once the database is updated with the recently renewed certificate after the reconfiguration of IFD and claims.
The following error can be seen in event viewer of the ADFS server (Application and Services Logs -> ADFS 2.0 -> Admin ) :-
