Hi fellow tech community participants,
I have an ADFS Server (Windows Server 2016) which has recently started to throw errors when trying to use https://adfs.contoso.com/adfs/portal/updatepassword to change a user password.
The user is getting a message like "user id or password is incorrect even though the username and password are correct.
In the Eventlog of the ADFS I can see a 407 Error with the following content:
Password change failed for following user:
Server on which password change was attempted:Error details:UserNotFound
What bothers me the most is that there seems to be no server on whicht the change was attempted.
Using nltest I get the following output:
C:\Windows\system32>nltest /DsGetDc:contoso.com /pdcGetting DC name failed: Status = 1355 0x54b ERROR_NO_SUCH_DOMAIN
I can ping the PDC just fine and I can see that it tried using that server 3 days ago when someone entered a wrong password in the change password dialog.
Does anyone know how to resolve this?
