Hello, I have troubles with "SID" and some users on my Etch servers. It's a new install before servers were in Sarge and all was ok. Distribution: Linux Etch, SaMBa, OpenLDAP, Gosa. (all from debian Etch) Architecture: - 1 "master" server, and few servers "slaves". - Openldap data from "PDC" Samba "master" are replicated on "slaves" servers (slurpd daemon) - passdb backend of "slaves" SaMBa are local: passdb backend = ldapsam:ldap://127.0.0.1/ on the replicated base. SID of master server is different from SID of slaves servers except for BDC of course. "net rpc join -U root" worked good on slave servers and slaves Domains are in the LDAP base of the master server. But I have theses error messages on slave servers: Message 1: Aug 20 16:34:13 slave1 smbd[5401]: User dupont with invalid SID S-1-5-21-(SID du Domaine)-3374 in passdb Aug 20 16:34:14 slave1 smbd[5401]: [2007/08/20 16:34:14, 0] passdb/passdb.c:lookup_global_sam_name(598) Aug 20 16:34:14 slave1 smbd[5401]: User root with invalid SID S-1-5-21-(SID du Domaine)-500 in passdb Aug 20 16:34:14 slave1 smbd[5401]: [2007/08/20 16:34:14, 0] passdb/passdb.c:lookup_global_sam_name(598) Aug 21 16:07:35 slave1 smbd[6123]: User root with invalid SID S-1-5-21-(SID du Domaine)-500 in passdb Aug 21 16:07:36 slave1 smbd[6123]: [2007/08/21 16:07:36, 0] passdb/passdb.c:lookup_global_sam_name(598) Aug 21 16:07:36 slave1 smbd[6123]: User nobody with invalid SID S-1-5-21-(SID du Domaine)-2998 in passdb Aug 21 16:07:36 slave1 smbd[6123]: [2007/08/21 16:07:36, 0] passdb/passdb.c:lookup_global_sam_name(598) Of course SID of the Domain is different from the SID of the local SaMBa but why these messages? For information I can browse SaMBa directories with windows users (dupont) but with a lot of error messages. MeMessages 2: I forced the SID of the Domain on one slave server (net setlocalsid) it's like i'd do for a BDC. The messages disappears Aug 21 15:57:51 esclave1 smbd[10470]: [2007/08/21 15:57:51, 0] auth/auth_domain.c:domain_client_validate(246) Aug 21 15:57:51 esclave1 smbd[10470]: domain_client_validate: unable to validate password for user guest in domain DOMAIN to Domain controller NUX. Error was NT_STATUS_LOGON_FAILURE. ==> user "guest" is a systeme user without password, how to say that to the samba server? Thank in advance
