Required key not available means that cifs.upcall — run by the kernel in response to the mount request — was not able to get a Kerberos ticket for the CIFS mount error(22): Invalid argument Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) Das sagt natürlich nicht allzu viel aus. Also Logs checken. tail 1) Capture debug messages from cifs.upcall. Restart rsyslog service and confirm that the log file /var/log/debug has been created which will log all messages. Attempt the call which will usually be the call to mount the cifs share. You should see the debug messages from cifs.upcall in /var/log/debug. 2) Strace cifs.upcall calls Required key not available means that cifs.upcall — run by the kernel in response to the mount request — was not able to get a Kerberos ticket for the CIFS server and from that generate the key needed for authenticating to the server (it would go in the kernel keyring of the client thread).cifs.upcall logs to daemon.debug; check those messages first sudo mount -t cifs --version mount from util-linux 2.23.2 (libmount 2.23.0: selinux, debug, assert) mount.cifs (cifs-utils): mount.cifs --version mount.cifs version: 6.2 Any idea where we could look into for further analysis?

There are 2 bug tracking systems which you should look at to see if your problem has already been reported: Samba bugzilla kernel section. Linux bugzilla cifs section. You can also ask questions on the linux-cifs mailing-list (linux-cifs@vger.kernel.org ) ( web archive here ). If you report a bug, a network capture and a kernel console log. mkdir /mnt/abc mount -t cifs //server/share /mnt/abc where server is your windows computer name (dns or netbios) and share is your windows shared directory. Depending on the access you give to your windows share are the credentials required: if you give your share 'Everyone' read (and write) access nothing else is required, otherwise you must add credentials at mount time

Verbosity can be turned up and extensions turned on. i feel the pain. There are at least 3 seemingly totally different ways to mount a remote samba filesystem and always have a hard time remembering where to look. The most common are ext2, ext3, ext4, xfs, btrfs, vfat, sysfs, proc, nfs and cifs. The programs mount and umount support filesystem subtypes. The subtype is defined by a '.subtype' suffix. For example 'fuse.sshfs'. It's recommended to use subtype notation rather than add any prefix to the mount source (for example 'sshfs#example.com' is deprecated). If no -t option is given, or if the auto. I have some problem with the cifs client of linux.
