Answer 1

Is the issue for all users coming from domain B?
What do you mean by "user logon process will roll back to the login page without any error message"?

The error code 0XC000006D suggests the username is incorrect or there are some other issues with the authentication materiel (maybe an NTLM version mismatch? you cut the event here, can you tell us what protocol was used for that attempt? It should be in the same event but lower).

Answer 2

Hello,
we have the same issue in our organization. Some users (random users) from one domain can't access the application using ADFS.
ADFS is installed in domain A, the users that have an issue are in domain B. Between domains, we have trust.

We received Event ID 4625. Follow the details:

Hello everyone,

I encountered the exact same issue recently.

Currently, I have two forests, Domain A and Domain B. Both domains are running with a two-way trust relationship.

The ADFS Server is operational in Domain A.

Users from Domain A can successfully sign in via ADFS. However, when a user from Domain B attempts to sign in via ADFS, we don't receive an error message, and the user is redirected back to the sign-in page.

Upon checking the Security Log on the ADFS Server, I noticed Events 4625.

Do any of you have suggestions or hints on how to resolve this issue? Any assistance would be greatly appreciated.
