This solution applies to Barracuda SSL VPNs, all firmware versions.
This issue affects Barracuda SSL VPN installations configured to use AD on Windows Small Business Server 2003
If you go to the Accounts page in Barracuda SSL VPN and hover over or edit an account, you may notice that the pop-up does not show any of that user's group memberships.
This is because in SBS by default, Authenticated Users is not a member of the Built-in Pre-Windows 2000 Compatible Access security group, where all other versions of Windows 2003 have it.
To fix this, log on to the SBS Server and run the AD Users and Computers program. Find the Pre-Windows 2000 Compatible Group in the Built-in folder, double-click it and go to the Members tab, click Add and type in Authenticated Users.
Click Check Names, which should underline Authenticated Users, then click OK twice to save the changes.
Now when your SSL VPN accounts cache refreshes, you should be able to see the link to users and groups working as expected.
