libwebauth12 binary package in Ubuntu Xenial s390x

 WebAuth is a cookie-based web authentication system built on top of
 Kerberos. It relies on a central authentication server that handles all
 user authentication for a domain and creates user authentication
 credentials for any web server that needs strong authentication.
 .
 This package contains the shared library used by the WebAuth modules,
 Perl bindings, and command-line utilities. It does token encoding and
 decoding and other lower-level parts of the WebAuth protocol.
