Problems With WatchGuard SSL VPN Firewall LDAP Authentication Using Windows Server 2003 Active Directory Log-in Credentials

 

I have a WatchGuard SSL VPN firewall, in which the VPN login's were

linked using LDAP to the Windows 2000 Active Directory (AD) accounts.

With this configuration, the users could login to the VPN using their

Windows 2000 AD credentials. When the Windows 2000 Server was

upgraded to Windows Server 2003, the AD no longer works with the

WatchGuard SSL VPN using LDAP. No configurations to the WatchGuard

SSL VPN firewall were changed prior to upgrading to Windows Server

2003. I have heard that this problem may be caused by Windows Server

2003's new Group Policy Objects (GPO) features, which may lock down

certain LDAP capabilities. If this is the case, which Windows Server

2003 GPO settings will need to be changed? If anyone who has such

knowledge and experience with getting Windows Server 2003's AD to work

with WatchGuard SSL VPN firewalls (using shared login credentials) can

help me, I would very greatly appreciate it.
