DansGuardian AD Groups

[o0steveo0o]

Hi all.  Have PfSense 2.1 + DG + Squid3 and SSO running.  For the best part all seems to be running well except for a few issues with DG groups.  AD group is called "ProxyRestricted".  If I add users to this group, wait for the group to sync the user is added to DG's user list but for whatever reason that user is still unable to authenticate to that group.  If I reboot the PfSense box or manually add/remove the user in the PfSense/DG console it works.  Also, is there a way to use nested groups?  e.g. I want to add the "Domain Users" group to "ProxyRestricted".

Cheers all.
