[linux-cifs-client] Can't mount more than one share at a time on Win2003 domain server

[Thomas Boutell]

Hello, cifs-gurus,

Using cifs I am unable to mount two shares at once on a single 
Windows 2003 server. The following output is reliably reproducible:

* * *

Executing mount -t cifs //windc1/salesperson1 /tmp/salesperson1 -o user=salesperson1,pass=p at ssw0rd,domain=ad
Success
Executing mount -t cifs //windc1/salesperson2 /tmp/salesperson2 -o user=salesperson2,pass=p at ssw0rd,domain=ad
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
Error, return code 65280
Executing umount /tmp/salesperson1
Success
Executing mount -t cifs //windc1/salesperson2 /tmp/salesperson2 -o user=salesperson2,pass=p at ssw0rd,domain=ad
Success
Executing umount /tmp/salesperson2
Success

* * *

When the mount fails, this appears in /var/log/messages:

Feb 14 15:31:25 adlincli1 kernel:  CIFS VFS: Send error in SessSetup = -13
Feb 14 15:31:25 adlincli1 kernel:  CIFS VFS: cifs_mount failed w/return code = -13

* * *

I am running a fully up2date'd Fedora Core 3 system. The
kernel version is 2.6.9, Fedora's sub-version 1.667. CIFS version is 
1.22 assuming the comments in CHANGES in the fs/cifs subdir of the
kernel source are a reliable way of determining that.

I'm would *love* to be able to reliably use cifs to log into home 
directories elegantly via pam_mount. Right now this is the only problem 
preventing that: one user at a time is not a very satisfying answer.

The Samba version, if relevant, is reporting itself as Version 3.0.10-1.fc3.

Thanks for any assistance!
