CIFS authentication failure when mounting DFS shares
Issue
- Error message "Permission denied" is returned when attempting to mount a
DFSshare from a Windows Active Directory domain:
# mount --verbose -t cifs //my_domain.com/DFS_root/dirA/dirB/dirC /mnt/my_mountpoint -o user=my_username,domain=MYDOMAIN,sec=ntlmi
Password:
mount.cifs kernel mount options: unc=//my_domain.comDFS_root,ip=1.2.3.4,ver=1,rw,user=my_username,domain=MYDOMAIN,sec=ntlmi,prefixpath=dirA/dirB/dirC,pass=********
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
- The CIFS kernel module complains about unexpected SMB signatures:
