Hi, I’m using OpenLDAP 2.4.7 and using the mirrormode and syncrepl. My setup has 2 LDAP nodes, one as master and other as slave through a VIP. When the master goes down, the slave will become master and vice-versa. At any point to keep both the LDAP in sync I'm using mirror mode and syncrepl. When one node , say A is up (that is the active node) and the other node B is down, I delete some LDAP entry from node A. THen when i start node B, the slapd on node B crashes and i see a core file also. I have attached the logs (node_A_ldap.out and node_B_ldap.out ) files. I’m using the following conf file. database bdb directory $MMAIL_VAR_DIR/ldap/ipu-mail-ldap suffix "o=mereonmail" rootdn "cn=admin,o=mereonmail" rootpw secret index objectClass,entryCSN,entryUUID pres,eq index mail,cn eq,sub overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 syncrepl rid=1 provider=ldap://${MMAIL_LDAP_PEER_HOSTNAME}:$MMAIL_LDAP_PORT bindmethod=simple binddn="cn=admin,o=mereonmail" credentials=ipunity filter="(objectClass=*)" searchbase="o=mereonmail" schemachecking=on type=refreshAndPersist interval=00:00:00:01 retry="60 +" mirrormode on serverID $NODE_ID PS: rid= 1 in both node A and node B. provider points to the other peer node. serverId= 1 on Node A and serverId= 2 on Node B Is this is know bug in OpenLDAP2.4.7??
