Message: %ASA-4-109031: NT Domain Authentication Failed: rejecting guest login for username.
Event 109031 is generated when a user connection is denied because the user tried to authenticate to an NT domain that had been configured for guest account access and the username was not a valid username on the NT server.
How could you resolve this situation?
In the case of a valid user, add an account to the NT server. If the user is not allowed access, no action is required.
