ldap_sasl_bind
^^^ this call shouldn't be here; on the contrary, this should result in
calling ldap_sasl_interactive_bind_s() from within back-ldap's
ldap_back_proxy_authz_bind(). I have no clue about why this is happening
since I've never tested this with GSSAPI (and I can't do it now). However
I've tested it with other SASL mechs (including DIGEST-MD5 and EXTERNAL)
and it worked as expected.
