[Samba] Problem with PDC OpenLDAP logon at Win2K/XP

[Nikolay Sergeyev]

Hello

I've installed Fedora Core 3 (Test 3, kernel 2.6.8x), with Samba 3.0.8 and OpenLDAP 2.2.13 . I've smb.conf, slapd.conf, ldap.conf, /etc/pam.d/system-auth, nsswith.conf almost same as described on Idealx site. I've very strange thing. If I add user ( for this operation I use smbldap-tools), I can log on by this user at my unix host (for example by ssh), I can logon by this user to Samba Domain at Win9x workstation, I can see this user using 'getent passwd' command, I can see this user in Samba database using "pdbedit -Lv" command,  but I can't logon by same user at every Win2k/XP workstations ( before I added those workstations to Samba domain successfully). By investigating I understand if I manually add this user in /etc/passwd ( I do it using vipw ) without setting password for user, then I can log on this user at WIn2k/XP. 
But why ?
If I get positive reaction on ssh login ( this user can do it), and I see user by 'getent passwd', so Unix user account operate. (if I understand pam_ldap works right).
If I see Samba user account 'pdbedit -Lv' command, and I can logon by user at Win9x ( I can see share NETLOGON on PDC from Win9x), so Samba account operate.

Thank you for advance for any reaction.
