[Samba] user name with a dot not working

[Robert Nedbal]

Hello,
I'm having problems with user names containing a dot. For example
"j.smith".

In our network we have Win2K PDC and a Samba server. smb.conf contains
this:
[global]
security = domain
password server = MYSERVER
username map = /etc/samba/smbusers
[myshare]
valid users = j.smith
write list = j.smith
etc...

/etc/samba/smbusers file contains this:
jsmith = j.smith

And Linux box with Samba server has an account for user 'jsmith'
(/home/jsmith).

So I'm trying to map 'j.smith' (windows user name) to 'jsmith' (linux user
name). But the problem is that when I try to access shares on samba server
I get NT_STATUS_WRONG_PASSWORD. I'm sure the password is entered
correctly.

[me at pc41 me]$ smbclient //SAMBASRV/webpages -U 'j.smith'
added interface ip=10.92.32.33 bcast=10.92.255.255 nmask=255.255.0.0
Password:
Domain=[MYDOMAIN] OS=[Unix] Server=[Samba 2.2.7a-security-rollup-fix]
tree connect failed: NT_STATUS_WRONG_PASSWORD

and in a log file on samba server I see:
[2003/12/16 17:53:39, 0] smbd/password.c:authorise_login(863)
  authorise_login: rejected invalid user nobody
                                        ^^^^^^^^^ <-- this is strange!
                                                  (why nobody?)
The same error I get from windows clients.

When I intentionally enter wrong password, I get in log file this:
[2003/12/16 17:11:50, 0] smbd/password.c:domain_client_validate(1619)
  domain_client_validate: unable to validate password for user J.SMITH in
domain MYDOMAIN to Domain controller MYSERVER. Error was
NT_STATUS_WRONG_PASSWORD.

When I inetntionally enter wrong user name, I get in log file this:
[2003/12/16 17:12:02, 0] smbd/password.c:domain_client_validate(1619)
  domain_client_validate: unable to validate password for user X.SMITH in
domain MYDOMAIN to Domain controller MYSERVER. Error was
NT_STATUS_NO_SUCH_USER.


When I remove 'jsmith = j.smith' from /etc/samba/smbusers and change unix
user to 'j.smith', everythig starts working. But I would like to use on
Linux usernames without a dot.

Thanks for your help, any ideas?

Best regards,
Robert
