We've been seeing this off-and-on for the last few months on our OES2SP2-Linux file servers. Trustee assignments made to groups don't seem to give any visibility to folders for end-users, but if the members of the group are granted trustees explicitly, they then get the rights. It doesn't seem to be time-sensitive (ie, some background process evaluating group memberships), and clearing connections to the servers and re-connecting doesn't produce any change in results. It's not 100% consistent or repeatable.

Has anyone else seen behavior like this before with OES2-L?
