Pacemaker uses resource agents to monitor various daemons, so i downloaded resource agent for slapd. Resource agent is just a script file (e.g. resource agent for slapd) and it executes same query as i do by hand, but slapd complains about "invalid dn": Here is how slapd resource was defined: ldap2:~# crm configure primitive slapd_mirrormode ocf:heartbeat:slapd params \ slapd="/usr/lib/openldap/slapd" config="/etc/openldap/slapd.conf" \ user="ldap" group="ldap" services="ldap:/// ldaps:/// ldapi:///" \ watch_suffix="dc=test,dc=org" \ bind_dn="uid=slapd-pcmk,ou=Services,dc=test,dc=org" \ password="P@ssw0rd," parameters="-o slp=on" \ meta migration-threshold="3" op monitor interval="10s"
I changed loglevel in slapd to `1' and see following in log:
[...]

The single quotes are part of the DN being sent. For example:
$ ldapsearch -x -D "'uid=bgmilne,ou=People,dc=ranger,dc=dnsalias,dc=com'" ldap_bind: Invalid DN syntax (34) additional info: invalid DN
yields:

slapd is not quoting the invalid DN, so the quotes are part of the DN being sent, which is obviously invalid due to the quotes.
I understand that there might be a problem in pacemakers `slapd' resource agent. Maybe it corrupts bind dn somehow...
Agent executes `monitor' operation, here is a snippet from resource agent code: ldap2:~# less /usr/lib/ocf/resource.d/heartbeat/slapd ... slapd_monitor() { ... options="-LLL -s base -x"
if [ -n "$bind_dn" ]; then options="$options -D '$bind_dn' -w '$password'"
This is wrong. Removing the single quotes in the line above should fix it.
