The checkpassword interface is used in many different ways:

I found checkpassword the easiest way to implement authentication against
FreeRADIUS. Using a perl script with

    $input = IO::Handle->new_from_fd(3, "r");

and
    
    my $output = IO::Handle->new_from_fd(4, "w");

and skipping the checkpassword-reply binary. This works fine on our server
for many years now but every time when I read some related questions on the
list, it seems that a more generic, not so crude interface would be a good
idea for a future version of dovecot.

Great. Thank you.
