This is a helper script to allow you to interactively login to a GlobalProtect VPN that uses SAML authentication.
Interactive login is, unfortunately, sometimes a necessary alternative to automated login via scripts such as zdave/openconnect-gp-okta.
gp-saml-gui uses GTK, which requires Python 3 bindings.
On Debian / Ubuntu, these are packaged as python3-gi, gir1.2-gtk-3.0, and
gir1.2-webkit2-4.0:
$ sudo apt install python3-gi gir1.2-gtk-3.0 gir1.2-webkit2-4.0
Then, set up a virtual environment that can access these system packages, activate it, and install the Python dependencies:
$ virtualenv --python=python3 --system-site-packages venv
$ . venv/bin/activate
$ pip install requests
Specify the GlobalProtect server URL (portal or gateway) and optional arguments.
This script will pop up a GTK WebKit2 WebView window.
After you succesfully complete the SAML login via web forms, the script will output
HOST, USER, and COOKIE variables in a form that can be used by
OpenConnect
(similar to the output of openconnect --authenticate):
$ eval $( gp-saml-gui.py -v vpn.company.com )

SAML response converted to OpenConnect command line invocation:
