Trouble is, RFC 2228 mandates that its the *client* that suggests
which auth protocol to use and the server is supposed to know which
auth protocols it can support. I don't see how that can be made to
work with PAM's current prompting mechanism.

Even in protocols like IMAP, where the client has to give the server
some control by issueing a CAPABILITY request, the server has to know
which authentication protocols it can support *before* actual
negotiation takes place. Similiar problem.

its easy to stop using Perl: I do it after every project
