Description of problem: Using "force user" option in smb.conf under defined 
share, smbd will crash

Version-Release number of selected component (if applicable): samba-3.0.23c-

How reproducible: 

To reproduce this problem, samba must be configured with windbind and using 
Windows ADS to authentify. Also, the problem will appear if a user tried to map 
a drive from Windows (net use x: \\samba\test) and this user doesn't have 
access right at filesystem level. Here is an example os the share:

        comment = Test Home Directory
        path = /home/test
        valid users = domain+test,domain+admin
        force user = domain+test <---------- Removing that option solve the 
                                             issue, but in my case, I really
                                             need it.
        force group = domain+management
        read only = no
        create mask = 0660
        directory mask = 02770
        nt acl support = yes

Actual results:
When it failed, I Windows will show me arror saying the share is no longer 
available and under snmd.log I have this crash dump from smbd process, but I'm 
not unable to retreive it...

Expected results:
Sucessfull network drive connection

Additional info:
This problem has been solve on latest release of Samba. Recompiling version 
3.0.24 solve the issue. Redhat should include this version into their
