=head1 NAME

B<Apache::AuthenPasswdSrv> - mod_perl Authen Handler

=head1 SYNOPSIS

  PerlAuthenHandler Apache::AuthenPasswdSrv->handler()

=head1 REQUIRES

Perl5.004_04, mod_perl 1.15

=head1 DESCRIPTION

B<Apache::AuthenPasswdSrv> is a mod_perl Authentication handler that
checks a users credentials against a domain socket server.  The included
server, B<passwd_srv.pl>, checks a username and password against an NIS
database using Net::NIS and ypmatch.  This release is very alpha.  The 
server protocol is not documented and transaction format will change.
The system has been running under light load at my office for about a 
month now, and no problems are know with the current release.
