Hi I have configured Samba samba-3.0.6-2.3E with openldap autentification and smbldap-tools-0.9.1 On the Win2k client, on "System properties" => "Network identification" => "Properties" => "Member of" => "Domain" i put AEIF ( the name specifie on smb.conf ) , the system ask me the login and passwd, and tell me that ins't correct ... but on the Samba server log : tail /var/log/samba/aeifzpro1.log [2005/06/22 15:57:00, 2] smbd/sesssetup.c:setup_new_vc_session(608) setup_new_vc_session: New VC == 0, if NT4.x compatible we would close all old resources. [2005/06/22 15:57:00, 2] passdb/pdb_ldap.c:init_sam_from_ldap(485) init_sam_from_ldap: Entry found for user: test2 [2005/06/22 15:57:00, 2] passdb/pdb_ldap.c:init_group_from_ldap(1902) init_group_from_ldap: Entry found for group: 513 [2005/06/22 15:57:00, 2] auth/auth.c:check_ntlm_password(305) check_ntlm_password: authentication for user [test2] -> [test2] -> [test2] succeeded [2005/06/22 15:57:01, 2] smbd/server.c:exit_server(571) Closing connections it seems i pass the autentifcation step with my Win2000 client netbios named "aeifzpro1" whith the user test2 ( this thing was declared with the smbldap-useradd.pl -w eifzpro1$ ) An idea ???
