samba - Dec 2005 - Can not login to the domain. User serg in passdb, but getpwnam() fails!

Hi everyone.


I am installing an Samba 3 PDC with an OpenLDAP backend.
I am currently having a problem when I try to login to the domain with 
my username and password. But no such problem when i am trying to join 
to domain or connect to a share.
So, i get the following error :

[2005/12/21 18:08:02, 1] auth/auth_util.c:make_server_info_sam(840)
User serg in passdb, but getpwnam() fails!
[2005/12/21 18:08:02, 0] auth/auth_sam.c:check_sam_security(324)
check_sam_security: make_server_info_sam() failed with 
'NT_STATUS_NO_SUCH_USER'
