I've been using Linux for a very long time, so I'm aware of how groups/users work.
I've got a few shell accounts and I'm trying to rig up a directory under one of the users that they all have access too. that directory's group ownership is a group to which all these users belong, and the permissions are set G+RX, so I should be able to cd into it. I was able to do this momentarily, but all of a sudden I just get "permission denied" now. Everything seems set up just fine. Is there any weird behavior that Dreamhost does that further prevents users from accessing one another's home direcotires?
