If the SASL EXTERNAL hooks in OpenLDAP only check whether OpenSSL is
enabled, then it won't work.  I imagine that you would have to change
OpenLDAP's EXTERNAL code to also check if GnuTLS layers are present.
That should be simple to add.

Btw, I recall that Cyrus SASL, or at least some of the Cyrus SASL
modules, depend on OpenSSL.  GNU SASL might be another SASL
alternative, and I have experience integrating it together with GnuTLS
(although not in OpenLDAP).
