Description of problem:

While Satellite 6 has support for consuming external authentication as provided by Apache is there, the only way of using that feature is in connection with sssd on IPA-enrolled machine. However, other external authentication mechanisms are possible besides those tied to sssd.

Namely, SAML is possible and should be easily configurable on Satellite 6. The proposal is to use mod_auth_mellon and (optionally) integrate with Ipsilon Identity Provider via some simple katello-installer parameters.

Version-Release number of selected component (if applicable):

Satellite 6.0.x.

How reproducible:

Deterministic.

Steps to Reproduce:
1. Attempt to configure Satellite 6 to consume external authentication/users via SAML, with Ipsilon or other IdP.

Actual results:

No katello-installer options.

Expected results:

There are katello-installer options to achieve that setup.
