Hello, we have a college setup. We have an Xserve G5 running OSX Server 10.4.8, all users on the network login via LDAP and there home directories are stored on the Xserve RAID. All clients are running 10.4.8 with Creative Suite installed. All works fine, apart from the fact that some users keep getting a window appear asking for the admin username and password when they open Acrobat 6 Pro. There does not seem to be a reason for it, some users don't have it appear at all.

I have tried assigning all read/write access to the Acrobat folder, then copying it to certain Macs via ARD and it still happens.
I have also added the Adobe PDF printer to everybodys printer list via Workgroup Manager Prefs and it still does it.

Can anybody please help?
