 Posted: Mon Dec 03, 2007 12:22 am Post subject: cifs not setting UID correctly |
 |
|
I am currently trying to get my samba shares (mounted via CIFS) to be able to written to as the local uid from the client machine. It is currently writing it as the user who mounts the samba share (username = remotemounter) not the user of who writes the file. I can see the file acls from the client. Id mapping should not be an issue because I user ldap for user accounts.
I am currently running net-fs/samba-3.0.27a on both server and client. I am using net-fs/mount-cifs-3.0.25c on the client.
example:
samba mount is mounted by "remotemounter" in fstab with setuids,credentials=***** options
write file as MyUsername to samba share
file has proper gid because that is forced by smb.conf
file has improper uid. It is written as uid=remotemounter. It is supposed to written as MyUsername
