Lemonldap::NG::Portal::Auth::CAS - Perl extension for building Lemonldap::NG
|

compatible portals with CAS authentication.
|

=head1 SYNOPSIS
|

=head1 DESCRIPTION
|
||||
|
||||
This library just overload few methods of Lemonldap::NG::Portal::Simple to use
|

CAS mechanism: we've just try to get CAS ticket.
|

See L<Lemonldap::NG::Portal::Simple> for usage and other methods.
