ACS 5.6 connected to AD, but gives error, when users try autenticate. ERROR: 24444

Hello Community,

 

Just as a start, I would like to refer that I already search a lot, and google a lot, and didn't find the solution for my problem.

The issue is:

 

I have a Cisco ACS 5.6 (evaluation copy) that I'm trying to integrate with an AD in Windows Server 2012. (I need to do it, because soon I'll have to implement one in a client.

 

The ACS connects to the AD successfully, etc.

But when I test the connection, it doesn't work.

 

ROUTER-LAB#test aaa group ACS acs-lab password legacy
Attempting authentication test to server-group ACS using tacacs+
User authentication request was rejected by server.

 

When I go see the logs, it says:

Active Directory operation has failed because of an unspecified error in the ACS

Anyone can help me out with this?
