SASL is a "glue" between LDAP and Kerberos, that translates an identity established through Kerberos AuthN to an LDAP Distinguished Name (among other possible uses). When communications between Kerberos and LDAP happen, SASL also provides encryption.
I have setup Kerberos, SASL, OpenLDAP and SSSD all on Fedora and it all works. I dont have to muck with SSL/TLS and the different implementations with their specific nuances. Though you dont know much about Kerberos, its not too difficult to implement. You seem to have the aptitude to do so. Might just be a matter of reading up on how to.
