I'm using freeradius with the rlm_ldap module to request users from a OpenLDAP server using the LDAPS protocol. Is there any best practice how to limit the accepted TLS versions to 1.2 and 1.3 on the LDAPS connection? SSL and TLS <= 1.1 should be denied. I found a "tls_min_version" option for the rlm_eap module, but not for rlm_ldap. Are there other possibilities than stripping down the used libssl?

libssl for can also be configured via /etc/ssl/openssl.cnf. You can us it to limit the acceptable chiphers and TLS versions and many other configuration settings. Grüße, Sven.
