Active Directory Troubleshooting
If your users are unable to connect using Active Directory, verify the following configurations:
•
•
Read-only Administrator – Users logging into this domain are treated as read-only
administrators and can view all information and settings, but cannot apply any changes to
the configuration. These users are presented with the admin login page.
The time settings on the Active Directory server and the SRA appliance must be
synchronized. Kerberos authentication, used by Active Directory to authenticate clients,
permits a maximum 15-minute time difference between the Windows server and the client
(the SRA appliance). The easiest way to solve this issue is to configure Network Time
Protocol on the System > Time page of the SRA Web-based management interface and
check that the Active Directory server has the correct time settings.
Confirm that your Windows server is configured for Active Directory authentication. If you
are using Window NT4.0 server, then your server only supports NT Domain authentication.
Typically, Windows 2000 and 2003 servers are also configured for NT Domain
authentication to support legacy Windows clients.
