Hi,
I am experiencing the same issue.
Our CPPM is currently not joined to any Active Directory domains.
However, it does have some Authentication Sources that are Active Directory domains and they are working without issue.
I am currently trying to add in a new source, but when the users attempt to authentication the same error message is generated.
I have tried few things, like adjusting the bind DN, and toggling "Allow bind using user password", as suggested here and in other posts.
I have read a few other posts in the forums about this error but can't seem to find what could be causing the issue in our case.
Any other suggestions?
Does joining the CPPM to an AD domain require a reboot?
Thank you,
Cheers
