supersedes the 1992 X/Open SMB Standard) as well as to perform best practice

similar files reside (usually /sbin). Although the helper software is not
required, mount.cifs is recommended. Eventually the Samba 3.0 utility program
"net" may also be helpful since it may someday provide easier mount syntax for

Linux clients is useful in mapping Uids and Gids consistently across the

Also note that "cat /proc/fs/cifs/DebugData" will display information about
