[Samba] smdb crash with parameter "force user" using Windows AD user (DOMAIN+user1)

Tue Oct 10 15:38:55 GMT 2006

Dear all,

I'm having problem with samba 3.0.23c. The smbd process will crash when
I have the following definition for a specific share:

[user1]
        comment = User1 Home Directory
        path = /u/management/user1
        valid users = domain+user1,sher+user2
        force user = domain+user1
        force group = sher+management
        read only = no
        create mask = 0660
        directory mask = 0770
        nt acl support = yes

After making tests, I've found that the problem is caused by the "force
user" and "force group". When I comment those lines, I can access the
share drive.

Here is a part of my log.smbd:

With the version 3.0.21b I do not have this problem. I'm using the same
smb.conf file I was using with 3.0.21b.

Please keep me in touch regarding this issue.
