Hello, I'm running openldap 2.3.43 on CentOS. I'm tring to setup a working master-slave sync system. I populate master server using slapadd -q -l from a ~160k entry ldif file. Every time I (re)start master server it takes long time to become available (about 20 minutes), in the logs I read these entries:

Nov 10 13:56:17 ldap01 slapd[2191]: hdb_search: 1 does not match filter Nov 10 13:56:17 ldap01 slapd[2191]: entry_decode: "" Nov 10 13:56:17 ldap01 slapd[2191]: <= entry_decode() Nov 10 13:56:17 ldap01 slapd[2191]: hdb_search: 2 does not match filter Nov 10 13:56:17 ldap01 slapd[2191]: entry_decode: "" Nov 10 13:56:17 ldap01 slapd[2191]: <= entry_decode() Nov 10 13:56:17 ldap01 slapd[2191]: hdb_search: 3 does not match filter Nov 10 13:56:17 ldap01 slapd[2191]: entry_decode: "" ... ... ... Nov 10 14:17:58 ldap01 slapd[32246]: hdb_search: 162959 does not match filter Nov 10 14:17:58 ldap01 slapd[32246]: entry_decode: "" Nov 10 14:17:58 ldap01 slapd[32246]: <= entry_decode() Nov 10 14:17:58 ldap01 slapd[32246]: send_ldap_result: conn=-1 op=0 p=0 Nov 10 14:17:58 ldap01 slapd[32246]: slapd starting

If I try to comment the syncprov section:

overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100

in slapd.conf the server startup is very quick (2-3 seconds).

Is there something wrong in what I'm doing? Is this very long startup normal?

Did you index entryCSN? If you didn't, then do (and do not forget to run slapindex before restarting slapd).
