We are using Xserve 10.3.9 for our ftp server. I have set up all of our customers with their own home folder and in addition I have made groups for all these customers so that one of our departments (lets call it internal user) can read/write/delete/execute into all these folders as well. I cannot give any of these administrative access. This department (internal user) is now a member of roughly 50 groups. The trouble I am having is that several of the folders will not allow the internal user which is part of the group to write to the folder. The customer which is only part of one group can still write and I (administrative user and owner of the folder) can still write but not the other member of the group. Is there a limit on how many groups to which a user can belong? They can still read however. This is only on some of the folders. The permissions are set to 775 and I have already tried to repair permissions. If there is a limit, how do I give the internal users access to all the folders below and none of the folders above while retaining the permissions for the end user?
