Hi, I run a samba-3.0.2a server as a simple file server in security=user mode. I have the following problem with a specific share: If I want to change the group permissions on a file (as a normal user owning the file) from within w2k using the security tab settings the new settings are ignored and instead the world/everyone settings are mapped to the group settings. If I change the permissions for world they are copied to the group settings too! All the users have "users" as their primary group and I mapped this group to the windows group "Users". Here are the relevant parts of my smb.conf [global] log file = /var/log/samba3/log.%m smb passwd file = /etc/samba/private/smbpasswd socket options = TCP_NODELAY SO_SNDBUF=8192 SO_RCVBUF=8192 guest user = nobody map to guest = bad user encrypt passwords = yes security = user max log size = 50 [data] nt acl support = yes writeable = yes public = no guest ok = no create mask = 0666 force create mode = 0666 path = /mnt/data security mask = 0666 force security mode = 000 I'm running gentoo linux the share is on an xfs fs with acl enabled and I build samba with acl support. Does anyone know what's going wrong here? thanx in advance achim~
