Thanks for your suggestions, Matt. ldapsearch functionality from the rados gw machines works fine using the same parameters specified in ceph.conf (uri, binddn, searchdn, ldap_secret). As expected I see network traffic to/from the ldap host when performing a search as well.
The only configuration I have in /etc/openldap/ldap.conf is 'TLSREQCERT demand' and TLS_CACERTDIR pointing at the location of my certdb... is there something else required here for ceph-rgw or does it look elsewhere?
