Manually Testing Login Credentials Against Active Directory
To test a username and password against the Active Directory, run the ad auth command in the Policy
Manager CLI.
This command manually checks against Active Directory to indicate whether or not a username and password
are valid.
1. Enter the following CLI command:
(server) # ad auth –u <username> –n <NetBIOS_domain_name>
n –u indicates the username.
n –n indicates the NetBIOS domain name.
For example:
(server) # ad auth –u administrator –n COLLEGE
You are prompted to enter the password.
If the username and password you provide in this command are correct, the following message is displayed:
INFO – NT_STATUS_OK: Success (0x0)
This message indicates that NTLM authentication (NTLM being the mechanism that W-ClearPass uses to
authenticate users) has succeeded.
