To verify that this is result of running in pacemaker,  i put the node in standby and start up Slapd manually, the nofile limit is shown as bound by /etc/security/limits.conf. However, if i online the node and let slapd start up through pacemaker, the limits seems to be inherited from pacemaker (as it should from forking) but with values that are not set in the limits.conf.

Only if that happens implicitly when limits.h is included.
Did you restart pacemaker after changing limits.conf?
