Re: (ITS#6567) Enable GSSAPI support and expose ldap_gssadpi_bind_s



Lastly, I note that it might be good for proponent of this feature to at =
least offer extensions to ldapwhoami(1) and other command line tools.  =
Aside from the educational value that would provide to developers in how =
this feature would be used along side other libldap features (such as =
ldap_sasl_interactive_bind_s), it would provide a means to test the =
code.  Of course, without support in OpenLDAP's slapd(8), testing would =
be cumbersome for many.
