[linux-cifs-client] Problem mounting Win2k shares with mount.cifs

Fri Apr 16 15:26:51 GMT 2004

Hi All,

About Salomon problems, I would like to add more data about and reports/debug of the applications.

I'm having the same problem, but I'm using Samba as the server. I tested it using:
- SLES8 + Samba-2.2.5
- SUSE Professional 9.0 + Samba-3.0.3pre1 (RPM package by SUSE ftp)
- Windows XP Professional (this is only a member server of a Samba domain)

I enabled the CIFS debug (echo 1 > /proc/fs/cifs/cifsFYI) to provide more information about this problem.

If I use an user that have a valid password, I can't connect to a share (in all S.O. listed bellow), and receive the following error:
"
mount error 22 = Invalid argument
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
"

In the file /var/log/messages, I have:

The only time that I obtained sucess I changed the Samba mode to "SHARE" and tested with a user that have a "blank password (valid)".  Using this mode, if the user has a valid password not blank, I can't connect to the server (very strange)!!!

My Linux client is a SUSE 9.0 with kernel 2.4.21-202. For test, I compiled the lastest version of "mount.cifs".

 I have been doing some tests regarding the problem I have been facing 
 with mount.cifs and I was able to solve the problem: 

 The original problem is that when attempting to mount a share on a Win2K 
 box from a Linux workstation with the command: 

 mount -t cifs //server/share /media/smb -o 
 user=TestUser,password=password,domain=TESTDOMAIN 

 I was getting the following error: 

 mount error 13 = Permission denied. 

 There was no problem in performing the mount using smbfs so the user and 
 password were valid. 

 I just tried a hunch and it worked. The working syntax is: 

 mount -t cifs //server/share/media/smb -o 
 user=TestUser/TESTDOMAIN,password=password 

 Apparently, mount.cifs does not compound the domain name with the 
 username when attempting to logon even when the domain is specified by 
 the appropriate parameter. This results in an invalid logon from the 
 server's perspective resulting in the "Permission denied" response. 

 Would this behavior be considered a bug or a restriction? 

 Thanks, 

 Salomon
