Mikrotik as RADIUS Client (IAS - Windows Server 2003)

Hello folks,

I need your help!!

I’m trying to use Mikrotik as a RADIUS Client, but I stuck in a following situation.

The log of the IAS - Windows Server 2003 says that the login was sucessfull, but in the user screen appear a message saying “Wrong user or password”.

The log of the Mikrotik has the following content:
