So we recently got a new part time client who had an ISA server. &nbsp;We replaced the ISA server for a SonicWall NSA 3500. &nbsp;They were using a Nortel Extranet Switch (1000) as a VPN connectivity device.<br />
<br />
Anyways, to make a long story short, I created the VPN to authenticated to LDAP, using the Users OU. &nbsp;<br />
<br />
I can create a new user, and they can authenticate just fine. &nbsp;Existing users cannot, the SonicWall says that it can't Authenticate to LDAP when performing a test on the SonicWall. &nbsp;So, i'm at a loss for what to do. &nbsp;All users new and old are in the same OU, groups are different...one is just a domain user another is a &nbsp;domain admin. &nbsp;Any ideas would be appreciated. &nbsp;My mind is toast right now.

Failure to Authenticate to LDAP through SonicWall NSA 3500

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
