Hello list, Openldap 2.4.45 here, on 1 producer and 4 consumers. ( I'll attach relevant parts of the configuration at the end of this message. ) Following the scripts from test059, I configured the producer to serve up a cn=config backend for the consumers. This seems to work nicely at first: When you start a consumer from a minimal config, it loads the producers schemafiles and the cn=config, and replication of the main database is fine. Also, when fi. changing the loglevel on the producers cn=config,cn=slave, the consumers pick up this change in their cn=config. However, when I modify an olcAccess line on the producers cn=config,cn=slave database, I get these errors on the consumer: slapd[26324]: syncrepl_message_to_entry: rid=002 DN: olcDatabase={1}mdb,cn=config,cn=slave, UUID: 7cff5ef6-90b1-1037-9d95-6dfd3149c2dc slapd[26324]: syncrepl_entry: rid=002 LDAP_RES_SEARCH_ENTRY(LDAP_SYNC_ADD) slapd[26324]: syncrepl_entry: rid=002 inserted UUID 7cff5ef6-90b1-1037-9d95-6dfd3149c2dc slapd[26324]: syncrepl_entry: rid=002 be_search (0) slapd[26324]: syncrepl_entry: rid=002 olcDatabase={1}mdb,cn=config slapd[26324]: null_callback : error code 0x43 slapd[26324]: syncrepl_entry: rid=002 be_modify olcDatabase={1}mdb,cn=config (67) slapd[26324]: syncrepl_entry: rid=002 be_modify failed (67) slapd[26324]: do_syncrepl: rid=002 rc 67 retrying trying to change the rdn, olcDatabase{1}mdb, on the consumer, which makes no sense to me.
