Which ssl library is your slapd compiled against? See the slapd-config
manpage for appropriate configuration for your ssl lib.

Hi Dan,

I found three libraries in mangpages of slapd-config i.e., OpenSSL, GnuTLS,
or Mozilla NSS

Correct, as OpenLDAP supports all three of those libraries. Consult your
system documentation for which library your binary slapd was linked
against.

This should give you a hint:

~# ldd `which slapd`
