[Pkg-samba-maint] Bug#505296: smbfs: "mount error 2 = No such file or directory" (with "sec=krb5")

Package: smbfs
Version: 2:3.2.4-1
Severity: important


I am unable to mount a share on my Windows XP machine using mount.cifs/smbmount. Connecting via smbclient works fine. Using smbmount in Etch works fine (as I understand, that worked in a different way?)

Workstation is part of a domain.

# mount.cifs //machine.fqn.com/Werk mnt/ --verbose -o user=user,dom=fqn.com,sec=krb5
parsing options: user=borisov,dom=olympus.f5net.com,sec=krb5

mount.cifs kernel mount options unc=//machine.fqn.com\Werk,ip=,pass=password,ver=1,user=user,dom=fqn.com,sec=krb5
mount error 2 = No such file or directory
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)

Using any other "sec" option results in a "mount error 13 = Permission denied" and a failed login entry in the WinXP event log.

I attach a network capture file. Looks like the server replies to the protocol negotiation request with STATUS_SUCCESS and then the client drops the connection. If this is true then it is a classic case of WTF??? ;-)

I'm not sure why smbclient authenticates successfully - looks like it is using some sort of NTLM authentication mode, but none of the NTLM "sec" options helped mount.cifs.

I would be happy to help troubleshoot this, as I really need to get this working. Please ask.
