NPS fails to authenticate user after realm replace. I need a help.

Z

Zarlyk

I have AD with domain xy.com for historical reason (real domain are replaced with XY and XYZ) but due to organization name change we got xyz.com domain and we are using for website and we want to use it for international wifi roaming.

Also we are not holder of xy.com domain

locally we are still using xy.com domain in AD because many internal services are integrated with it and in use.
We are planning to migrate to new domain in the future fully.

For now i need to authenticate wifi users with xyz.com domain (we don't have any problem authenticating users wit xy.com domain)

To do this i used realm replace. But i am now having error :
Reason Code: 16
Reason: Authentication failed due to a user credentials mismatch. Either the user name provided does not map to an existing user account or the password was incorrect.

HOW this problem can be solved ?

log shows that realm replace is working fine:

Network Policy Server denied access to a user.

Contact the Network Policy Server administrator for more information.
