Active Directory Server

4-Port SSL/IPSec VPN Router

Appendix D

Troubleshooting

If your users are unable to connect via Active Directory,

check the following:

The time settings between the Active Directory

server and the Router must be synchronized.

Kerberos authentication, used by Active Directory

to authenticate clients, permits a maximum of a 15-

minute time difference between the Windows server

and the client (the Router).
Make sure that your Windows server is configured

for Active Directory authentication. If you are using a

Windows NT 4.0 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.
