Network groups are "fetching" on Xsan Volumes ONLY through Finder
We're using an all apple OD infrastracture with 10.7.4 and Xsan 2.3 and for the past year or so have been expiriencing this fetching issue ever since 10.6.
Not a while ago we've came across Apple's offical article on how-to fix hexadecimal group ID's such as FFFFEEEE-DDDD-CCCC-BBBB-AAAA82000400 from http://support.apple.com/kb/TS3556.
After reading Apple's article we've found out that the problem occures whenever a user logs into the machine BEFORE OD communications is completed.
To get things to work, we usually unmount the Xsan volume and then re-mount whenever the user is ALREADY logged in. This has worked for us for a couple of months till we came across a new problem; After re-mounting we're able to see the right permissions on TERMINAL but on FINDER it's still fetching.
Finder vs. Terminal:
I've tried re-launching Finder without getting lucky, it seems like every time I re-launch Finder a different network group appears as "Fe tching..."
