Is there a particular order that the overlay syncprov directive needs to be at? I added the following lines to my master slapd.conf (after removing the replica and replog entries):
overlay syncprov
syncprov-checkpoint 100 10
syncprov-sessionlog 100
under the 'database bdb' section, then further down, modified index for:
index objectClass,entryCNS,entryUUID eq
as the OpenLDAP Software 2.3 admin's guide suggested.
but when I run slapd on the master I get:
--------------------------------
Starting OpenLDAP: slapd - failed.
The operation failed but no output was produced. For hints on what went
wrong please refer to the system's logfiles (e.g. /var/log/syslog) or
try running the daemon in Debug mode like via "slapd -d 16383" (warning:
this will create copious output).
Below, you can find the command line options used by this script to
run slapd and slurpd. Do not forget to specify those options if you
want to look to debugging output:
slapd -g openldap -u openldap
--------------------------------
so i ran the 'slapd -d 16383' and I get:
......
......
line 72 (overlay syncprov)
overlay "syncprov" not found
/etc/ldap/slapd.conf: line 72: <overlay> handler exited with 1!
slapd destroy: freeing system resources.
slapd stopped.
connections_destroy: nothing to destroy.
