Hi: I'm trying to integrate Samba and LDAP (Samba working as a PDC). While trying to add a computer to the domain, this is what I get (This is not a production server, so there is no problem with password revealing): [2003/05/28 18:59:00, 2] passdb/pdb_ldap.c:get_single_attribute(435) get_single_attribute: [userWorkstations] = [<does not exist>] [2003/05/28 18:59:00, 2] passdb/pdb_ldap.c:get_single_attribute(441) get_single_attribute: [rid] = [3000] [2003/05/28 18:59:00, 2] passdb/pdb_ldap.c:get_single_attribute(441) get_single_attribute: [primaryGroupID] = [3001] [2003/05/28 18:59:00, 2] passdb/pdb_ldap.c:get_single_attribute(441) get_single_attribute: [lmPassword] = [E52CAC67419A9A220CEC7D55CCC350DD] [2003/05/28 18:59:00, 2] passdb/pdb_ldap.c:get_single_attribute(441) get_single_attribute: [ntPassword] = [489DC27E7F41B2F1482B8B72B9F593D7] [2003/05/28 18:59:00, 2] passdb/pdb_ldap.c:get_single_attribute(441) get_single_attribute: [acctFlags] = [[UX ]] [2003/05/28 18:59:00, 4] smbd/password.c:smb_password_ok(475) smb_password_ok: Checking SMB password for user test [2003/05/28 18:59:00, 5] smbd/password.c:smb_password_ok(489) smb_password_ok: challenge received [2003/05/28 18:59:00, 4] smbd/password.c:smb_password_ok(499) smb_password_ok: Checking NT MD4 password [2003/05/28 18:59:00, 4] smbd/password.c:smb_password_ok(504) smb_password_ok: NT MD4 password check failed [2003/05/28 18:59:00, 4] smbd/password.c:smb_password_ok(518) smb_password_ok: Checking LM password [2003/05/28 18:59:00, 4] smbd/password.c:smb_password_ok(523) smb_password_ok: LM password check failed [2003/05/28 18:59:00, 2] smbd/password.c:pass_check_smb(575) pass_check_smb failed - invalid password for user [test] [2003/05/28 18:59:00, 1] smbd/reply.c:reply_sesssetup_and_X(1023) Rejecting user 'test': authentication failed [2003/05/28 18:59:00, 3] smbd/error.c:error_packet(109) error packet at smbd/reply.c(1025) cmd=115 (SMBsesssetupX) NT_STATUS_LOGON_FAILURE [2003/05/28 18:59:00, 5] lib/util.c:show_msg(268) I guess the attributes are OK. The passwords where generated with mkntpwd (mkntpwd -L password -N password) Thanks a lot! Gabriel.
