Hello everyone. I have a big problem releated to 2 OpenLdap configured in N-Way Multi-Master Configuration. My problem isn't on replication, that works, but on authenticating users on DIT !!! Infact when an user tries to simply authenticate himself on DIT with ldapsearch -x -D &#39;uid=example(a)gmail.com,ou=people,dc=example,dc=com&#39; -w 'password' he receives an ldap_bind: Invalid credentials (49) error. Disabling configurations for multi master replication the same user is able to search on DIT. Following there is one slapd.conf of server 1... allow bind_anon_dn # Schema and objectClass definitions include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/inetorgperson.schema # Additional schemas pidfile /var/run/openldap/slapd.pid argsfile /var/run/openldap/slapd.args # Read slapd.conf(5) for possible values loglevel 0 modulepath /usr/lib64/openldap moduleload syncprov.la serverID 001 backend bdb # FIXME: puppet database bdb suffix "dc=example,dc=com" directory /var/lib/ldap rootdn "cn=admin,dc=example,dc=com" rootpw password checkpoint 512 30 dbconfig set_cachesize 0 2097152 0 dbconfig set_lk_max_objects 1500 dbconfig set_lk_max_locks 1500 dbconfig set_lk_max_lockers 1500 #allows read access from all consumers access to * by dn.base="cn=admin,dc=example,dc=com" read by * break syncrepl rid=000 provider=ldap://ldap-be2 type=refreshAndPersist retry="5 5 300 +" searchbase="dc=example,dc=com" attrs="*,+" bindmethod=simple binddn="cn=admin,dc=example,dc=com" credentials=password ########################################################### index objectclass eq index entryCSN eq index entryUUID eq index uidNumber eq index gidNumber eq index cn pres,sub,eq index sn pres,sub,eq index uid pres,sub,eq index displayName pres,sub,eq # mirror mode essential to allow writes #and must appear after all syncrepl directives mirrormode TRUE # define the provider to use the syncprov overlay # (last directives in database section) overlay syncprov # # contextCSN saved to database every 100 updates or ten minutes syncprov-checkpoint 100 10 Slap.conf of 2th server is a copy of this with different serverID and provider.
