Description of problem:
Mounting a share on a win2003k server(and other winxp/win2k machines
in an Active Directory domain) oopses the kernel when ExtendedSecurity
is on. 

Version-Release number of selected component (if applicable):
kernel-2.6.5-1.358

How reproducible:
Always

Steps to Reproduce:
1. Turn on ExtendedSecurity
   echo 1 > /proc/fs/cifs/ExtendedSecurity 
2. Mount a share
   mount -t cifs //grimm/Documents /mnt/Documents/ -o
user=xxx,password=yyy

    

Actual Results:  Kernel oops:
 CIFS VFS: cifs_mount failed w/return code = 1
Unable to handle kernel NULL pointer dereference at virtual address

 printing eip:

Expected Results:  Atleast the kernel not to oops. And preferrably the
share to get mounted ;)


Additional info:

I had this working on RH 8.0 with cifs 1.x I compiled myself.
Without the ExtendedSecurity the mount fails
with 
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)

Ethereal shows it's some auth negotiating that fails.

Trying with smbfs I only get:
cli_negprot: SMB signing is mandatory and we have disabled it.
3117: protocol negotiation failed
SMB connection failed
