Hi Rob,

The CSR is generated within the web UI by following this section "Web UI:
Requesting new certificates" (
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/linux_domain_identity_authentication_and_policy_guide/certificates
)

I am looking to perform an authenticated ldapsearch using certificate-based
authentication so I don't have to pass username and password onto the
command line when searching against cn=groups,cn=accounts. Looks like only
authenticated ldapsearch will yield memberOf info (usernames that belong to
the group), but an anonymous ldapsearch will only yield group container
info without memberOf UIDs.

This document (
https://access.redhat.com/documentation/en-us/red_hat_directory_server/12/html/securing_red_hat_directory_server/assembly_configuring-certificate-based-authentication_securing-rhds
) says we need to have .ldaprc which include user's private key, therefore
my original question.

LDAPTLS_CACERT=/home/user_name/CA.crt
LDAPTLS_KEY=/home/user_name/user.key
LDAPTLS_CERT=/home/user_name/user.der

Will my certificate-based ldapsearch work without user.key defined?

so far I haven't been able to perform the ldapsearch because I am getting:

ldap_start_tls: Can't contact LDAP server (-1) additional info:
error:1416F086:SSL routines:tls_process_server_certificate:certificate
verify failed (self signed certificate in certificate chain).

Any pointers will be greatly appreciated!
