** Description changed: Binary package hint: linux-image-2.6.38-7-server When a CIFS share has remote DFS links, the user is unable to access the mount properly. A short summary, where RemoteDir is a DFS to another server: # mount.cifs //dfs.main.org/ test/ -o user=WORKGROUP/USER,noserverinode # ls test/ RemoteDir # ls test/RemoteDir/ ls: cannot open directory test/RemoteDir: Not a directory # umount test % And again, now with both ls on one line # mount.cifs //dfs.main.org/ test/ -o user=WORKGROUP/USER,noserverinode # ls test/; ls test/RemoteDir RemoteDir ls: reading directory test/RemoteDir/: Object is remote # umount test % Now chdir directly, without doing an ls (this is important) # mount.cifs //dfs.main.org/ test/ -o user=WORKGROUP/USER,noserverinode # cd test/RemoteDir test/RemoteDir# ls file1 file2 test/RemoteDir# cd ../../; umount test % However, lower case works normally # mount.cifs //dfs.main.org/ test/ -o user=WORKGROUP/USER,noserverinode # cd test test# ls RemoteDir test# ls remotedir file1 file2 test# ls RemoteDir ls: cannot open directory test/RemoteDir: Not a directory # umount test Note that unmounting is very important. After a mistake, (e.g. chdir does not work after ls), the share has to be remounted in order to chdir directly. The problem is basically described here, except for report on lower case access: http://www.mail-archive.com/linux-cifs@vger.kernel.org/msg01848.html However, those patches are already in the 2.6.38 kernel (currently running linux-image-2.6.38-7-server (rev 37)), and the problem still persists. On mounting, the kernel complains about: CIFS VFS: Unexpected SMB signature but no further complains on chdir/ls to the (DFS) mounts. I am pretty sure this is a kernel problem, as downgrading to 2.6.32-21-server (Lucid kernel) solves all problems (that is, keyutils, time, credentials etc. are installed correctly).
