1. Feature Overview: Enable Palo Alto Global Protect (PAGP) with SAML authentication working on the Ubuntu desktop supported via 20.04 LTS.

We propose 2 options:

Option 1: Provide a backport of the OpenConnect and NetworkManager-OpenConnect packages from the Ubuntu Daily Build to Ubuntu 20.04 that will allow PAGP SAML authentication to work (it works in the current daily build for 23.10).

OpenConnect version: v9.12-1
NetworkManager-OpenConnect version: 1.2.10-1

Option 2 (Preferred Option): Provide a backport of the 'gp-saml-gui' package which will allow PAGP SAML authentication to work (the current daily build for 23.10 will need to be updated first).

gp-saml-gui minimum required version: 0.0~git20230417-1
gp-saml-gui current version (Ubuntu 23.10 daily build): 0.0~git20220831-1
