Hello, I run a samba (v3.0.10) PDC and openLdap server on the same machine. They work fine, except sometimes the smb server cannot contact the ldap server. From a windows client, it looks like the server gets stuck, and it takes a few minutes before the shares are available again. In the /var/log/messages file, i get these error messages : -------------------------------------------------------------------- Apr 15 05:59:42 pdc smbd[27260]: [2009/04/15 05:59:42, 0] lib/smbldap.c:smbldap_search_suffix(1155) Apr 15 05:59:42 pdc smbd[26860]: failed to bind to server with dn= cn=Manager,dc=mydomain,dc=fr Error: Can't contact LDAP server Apr 15 05:59:42 pdc smbd[27261]: [2009/04/15 05:59:42, 0] lib/smbldap.c:smbldap_search_suffix(1155) Apr 15 05:59:42 pdc smbd[27214]: ldapsam_search_one_group: Problem during the LDAP search: LDAP error: (unknown) (Timed out) Apr 15 05:59:42 pdc smbd[27254]: smbldap_search_suffix: Problem during the LDAP search: (unknown) (Timed out) Apr 15 05:59:42 pdc smbd[27256]: failed to bind to server with dn= cn=Manager,dc=mydomain,dc=fr Error: Can't contact LDAP server Apr 15 05:59:42 pdc smbd[27258]: failed to bind to server with dn= cn=Manager,dc=mydomain,dc=fr Error: Can't contact LDAP server Apr 15 05:59:42 pdc smbd[27238]: [2009/04/15 05:59:42, 0] lib/util_sock.c:write_socket(455) Apr 15 05:59:42 pdc smbd[27249]: getpeername failed.

Does anyone know what's going on ? I don't know if the errors are related. I don't know either why nmbd tries to contact 169.254.2.2, which looks like a dummy address... Thanks in advance for your help. Tanguy
