The twisted maze of Samba authenticaion has just had a 4 lane highway
driven straight through it. If you have a look a the curent HEAD code,
you will see a (resaonably) sane interface to these things (start at
check_password()), despite the challange-response nature of the
potocol. We are about to add loadable modules to this, and if anybody
wants to write a plaintext-krb5 module I would welcome it.
