<AuthBy TACACSPLUS> provides authentication via a TacacsPlus
server. It supports authentication only, not accounting or authorisation.
It requires the Authen::TacacsPlus module. It is part of CPAN. For more
information, see
Section 2.1.2. Use at least version
TacacsPlus-0.15.tar.gz. Earlier versions do not work
properly. Version 0.15 supports PAP authentication only. Later versions
support both PAP and CHAP.
<AuthBy TACACSPLUS> understands also the same parameters as
<AuthBy xxxxxx>. For more information, see
Section 3.32.
