Hi, i have a running samba+ctdb installation with samba as a domain-member. everything works but the acl's. The users want to be able to set permissions on the share. glusterfs does not support extended acls, so i am using acl_xattr. xattr is installed and i can manually set attributes using setfattr on the shared-directory. if i try to set the permissions using a winxp client i'll get a "Permissions Denied". It's strange that the file is also "Write Protected" in the Windows-File-Properties. At the samba-server the file's owner is the user i am using, and has 777-Rights. I have the same problem when i use acl_tdb. Does anyone have an idea? This is my config: glusterfs (xfs-backend) + ctdb Samba(3.4.8): [global] workgroup = OFFICE realm = OFFICE.MAY.CO.AT netbios name = DSLIN server string = %h server security = ADS obey pam restrictions = Yes password server = winserver.example.com pam password change = Yes passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . unix password sync = Yes log file = /var/log/samba/log.%m max log size = 1000 clustering = Yes dns proxy = No panic action = /usr/share/samba/panic-action %d idmap backend = tdb2 idmap uid = 10000-20000 idmap gid = 10000-20000 template homedir = /mnt/gluster/daten/homes/%U template shell = /bin/bash winbind enum users = Yes winbind enum groups = Yes winbind use default domain = Yes [homes] comment = Home Directories path = /mnt/gluster/daten/homes/%U valid users = %S read only = No create mask = 0700 directory mask = 0700 browseable = No browsable = No [share] path = /mnt/gluster/daten/share/ read only = No inherit permissions = Yes inherit acls = Yes guest ok = Yes map acl inherit = Yes vfs objects = acl_xattr
