bind() and SASL authentication via GSSAPI

[Achim Grolms]

Hello,

I am maintaining a module GSSAPI.pm that is a Adapter to
the RFC2477 C-Bindings.
<http://perlgssapi.sourceforge.net/>

My idea was to write an adapter that implements
the Authen::SASL interface, using GSSAPI.pm.

I think that can be useful when using the Net::LDAP module.

RFC 2222 "Simple Authentication and Security Layer (SASL)"
describes the GSSAPI over SASL integration.
In RFC 2222 multiple steps of

while (SASL not finished) {
   gssapi-call()
   send()
   recv()
}

but the bind() Method of Net::LDAP
does only one call to the Authen::SASL object
and only one send( ).

But has'nt ist to do multiple steps of SALS, send, recv()?

My question:
is bind() doing steps wrong or is my thinking and understanding of this wrong?

Can you help?

Thank you,
Achim Grolms
