Yes you are right, I repeated the import via slapcat to test and got this error message: ~ # slapadd -w -q -f /etc/openldap/slapd.conf -l /backup.ldif 50f98421 mdb_monitor_db_open: monitoring disabled; configure monitor database to enable -#################### 100.00% eta none elapsed 09m18s spd 4.6 M/s Closing DB...Error, entries missing! entry 1156449: cn=1356155776-83002,ou=... ,... ,ou=root (I shortened the entry DN in output with "...")

Yes, will ask in the mailing list for additional information not directly releated to this SEGV. Thanks Kindly regards Maike

Yes the fix worked (I downloaded the latest openldap.tar.gz on your gitweb and installed it). Now slapd starts after having converted to cn=config But after the conversion my ldapsearch returns an 80 error (with slapd.conf it worked, the data from PostgreSQL where returned) Thus my question : are there other steps to be taken after the conversion (all I did was : slaptest -f slapd.conf -F slapd.d) I don't think this has something to do with that 7499 bug, so I'll post the question on the technical mailing list (but if nobody bumped into that 7499 bug before, it logically means that nobody is using back-sql with cn=config yet) ldapsearch -x -h localhost -b "dc=example,dc=com" "(objectClass=*)" # extended LDIF # # LDAPv3 # base <dc=example,dc=com> with scope subtree # filter: (objectClass=*) # requesting: ALL # # search result search: 2 result: 80 Other (e.g., implementation specific) error # numResponses: 1 Le 24/01/2013 04:46, Howard Chu a écrit : > Benin Technologies wrote: >> >>>>Yes, it's a bug.

Re: (ITS#7498) Openldap syncrepl issue
by arunkumar_1123＠yahoo.com 23 Jan '13

23 Jan '13

> MMR has supported delta-syncrepl since 2.4.27. You should use it. I did consider delta-syncrepl, but given the high write load expected, I was not sure if it was the right decision. I am expecting an average load of 50-100 writes per second, and with 1 backup provider, and 10 consumers, it might get heavy on the provider which is serving the writes, given that OpenLDAP would be maintaining another DB for the access log. But with this syncrepl issue, it looks like I need to change the replication mode to refreshAndPersist anyway. As such it looks like delta syncrepl is also refreshAndPersist too. Is there any recommendation between simple refreshAndPersist and delta-syncrepl with refreshAndPersist for high write loads? Thanks PS: I see that delta syncrepl is compatible with MMR which I presume to be MultiMaster. I hope it works with Mirror Mode too. I did not find any documents supporting this.
