[ovirt-users] Ovirt AD auth setup issue

I need a help to resolve Ovirt AD auth setup issue. I have setup ovirt-engine-4.2 and I am trying to integrate with AD for user authentication. Using (ad.properties) I am able to bind to AD, however test login is failing with "Invalid credentials" LOG --- FINEST: message = 80090308: LdapErr: DSID-0C090400, comment: AcceptSecurityContext error, data 52e, v1db1 API: <--Authn.InvokeCommands.AUTHENTICATE_CREDENTIALS profile='abc.internal' result=CREDENTIALS_INCORRECT SEVERE Authn.Result code is: CREDENTIALS_INCORRECT ---- I confirm the credentials is correct.
