gp-saml-gui
|
|
===========
|
|
|
|
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](https://github.com/zdave/openconnect-gp-okta).
|
|
|
|
Installation
|
|
============
|
|
|
|
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
|
|
```
|
|
|
|
How to use
|
|
==========
|
|
|
|
Specify the GlobalProtect server URL (portal or gateway) and optional
|
|
arguments, such as `--clientos=Windows` (because many GlobalProtect
|
|
servers don't require SAML login, but apparently omit it in their configuration
|
|
for OSes other than Windows).
|
|
|
|
This script will pop up a [GTK WebKit2 WebView](https://webkitgtk.org/) window.
|
|
After you succesfully complete the SAML login via web forms, the script will output
|
|
`HOST`, `USER`, `COOKIE`, and `OS` variables in a form that can be used by
|
|
[OpenConnect](http://www.infradead.org/openconnect/juniper.html)
|
|
(similar to the output of `openconnect --authenticate`):
|
|
|
|
```sh
|
|
$ eval $( gp-saml-gui.py --clientos=Windows vpn.company.com )
|
|

SAML response converted to OpenConnect command line invocation:
|
|
|
|
echo 'blahblahblah' |
|
|
openconnect --protocol=gp --user='foo12345@corp.company.com' --os=win --usergroup=prelogin-cookie:gateway --passwd-on-stdin vpn.company.com
|
|
|
|
$ echo $HOST; echo $USER; echo $COOKIE; echo $OS
|
|
https://vpn.company.com/gateway:prelogin-cookie
|
|
foo12345@corp.company.com
|
|
blahblahblah
|
|
win
|
|
|
|
$ echo "$COOKIE" | openconnect --protocol=gp -u "$USER" --os="$OS" --passwd-on-stdin "$HOST"
|
|
```
