Description Thomas Boutell 2005-02-21 11:44:38 UTC
Mounting two different shares on a Windows 2003 SP1 RC1 server with two
different sets of credentials fails in CIFS as found in Fedora's 2.6.9-1.724_FC3
kernel. The second mount attempt fails. Unmounting the first share allows the
second mount to succeed. I have no reason to believe the problem would be any
different on vanilla WIN2003 but I mention SP1 RC1 for completeness. 

See the following output, which is followed by /var/log/messages output.

[root@adlincli1 ~]# perl demo-bug
Executing mount -t cifs //windc1/salesperson1 /tmp/salesperson1 -o
user=salesperson1,pass=p@ssw0rd,domain=ad
Success
Executing mount -t cifs //windc1/salesperson2 /tmp/salesperson2 -o
user=salesperson2,pass=p@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 mount -t cifs //windc1/salesperson2 /tmp/salesperson2 -o

Comment 1 Steve French 2005-04-02 00:28:25 UTC
Fixed in cifs vfs in cifs development tree (soon will be in 2.6.12-pre-mm tree).

Patch can be seen at
http://cifs.bkbits.net:8080/linux-2.5cifs/gnupatch@424e48c6f3M3fhXntOe7JN1XXP4uQA

I will update the linux-cifs-client subversion tree later this weekend (and
produce a replacement version of the fs/cifs directory on the Samba ftp download
site).

I expect this to make 2.6.12 kernel.
