Hi, I have noticed a problem in OpenLDAP multimaster 2.4.44 with MDB backend. I did the following steps: i)
Add four entries into Master 1 (using slapadd with option -w). ii)
Configure Master 1 and Master 2 in Multi Master mode. Syncrepl information is given below: ############## Master1 Starts port (2016) ############## syncRepl rid=100 provider=ldap://xx.xx.xx.xx:2017 type=refreshAndPersist retry="5 + 5 +" searchbase="dc=my-domain,dc=com" attrs=* interval=00:00:00:09 schemachecking=off bindmethod=simple binddn="cn=Manager, dc=my-domain,dc=com" credentials=secret mirrormode on overlay syncprov # contextCSN saved to database every 100 updates or ten minutes syncprov-checkpoint 100 10 syncprov-sessionlog 100 ############## Master1 Ends ############## ############## Master2 Starts port (2017) ############## syncRepl rid=100 provider=ldap://xx.xx.xx.xx:2016 type=refreshAndPersist retry="5 + 5 +" searchbase="dc=my-domain,dc=com" attrs=* interval=00:00:00:09 schemachecking=off bindmethod=simple binddn="cn=Manager, dc=my-domain,dc=com" credentials=secret mirrormode on overlay syncprov # contextCSN saved to database every 100 updates or ten minutes syncprov-checkpoint 100 10 syncprov-sessionlog 100 ############## Master2 Ends ############## iii)
These four entries get replicated on the Master 2 correctly and are visible from ldap browser accurately. iv)
Add three more entries to Master 1. (using slapadd with option -w) v)
After restarting both Master 1 and Master 2, on Ldap Browser the new added entries are visible in Master 1 correctly. But in Master 2, all the previous entries got missing. Ldap browser is giving error “No entries returned” ( It seems
just like Master 2 DB got empty) vi)
But then I execute ldapsearch command on Master 2 as given below: ################################################### ldapsearch -h xx.xx.xx.xx -p 2017 -b "dc=my-domain,dc=com" ################################################### The above command returns all the entries exactly same to the Master 1 with the below search response: # search result search: 2 result: 0 Success # numResponses: 10 # numEntries: 9 Now I am unable to understand how it this possible that the entries exist in the DB but not showing through Ldap browser. ( I have checked Master 2 entries in different ldap browsers too) But it is just showing empty DB. Master 1 entries are showing correctly in Ldap browser. Context CSN for both the servers is same as given below: ################################## ldapsearch -H ldap://xx.xx.xx.xx:2016 -LLL -x -s base -b "dc=my-domain,dc=com" contextCSN dn: "dc=my-domain,dc=com" contextCSN: 20160705065521.205150Z#000000#000#000000 ldapsearch -H ldap://xx.xx.xx.xx:2017 -LLL -x -s base -b "dc=my-domain,dc=com" contextCSN dn: "dc=my-domain,dc=com" contextCSN: 20160705065521.205150Z#000000#000#000000 ################################## Can you please let me know how it can happen and how to solve this problem.
