Not sure if this is what I'm looking for but if it's possible with samba, I'd appreciate pointers at the correct documentation. We've got a bunch of filespace shared out onto our samba server from a fileserver that doesn't support ACLs, we're stuck using basic rwxr-x---- type permissions. Each share is assigned to a Unit so we've controlled access by group and put members of the unit into the group or just listed the users. However, the units want shares broken into subfolders to which group members have read / write or no access. Basic file permissions mean doing this with further groups and with people being in multiple units, we've soon run into the 16 group limit. (Samba's running on Solaris and the filespace is an NFS mount) So on to the question. Can I use samba to overlay file permissions over the top of these shares which could either be ldap group or user based, thus leaving a units files all owned by the same underlying user/group and if not has anyone come across and solved this problem another way? Pointers welcome. Thanks, Duncan -- The University of St Andrews is a charity registered in Scotland : No SC013532
