Unfortunately it does not. There is specific code handling
{md5} / {sha1} / {crypt} / {crypt16} spotted in the already-crypted
(second) argument, deciding what sort of encryption to apply to
the cleartext (first) argument before comparison.

Calling a ${perl } expansion in an authenticator's server_condition option
(thanks, Kai!) sounds like the best bet. Looks like you need
both Crypt::Blocwfish and Crypt::CBC though.
