openconnect-ms-auth

Openconnect MS-Auth

This package allows you to authenticate with your MFA enabled Microsoft-Account into the openconnect VPN client.

It uses selenium to open the login webpage and fill in the form details. At the end, it fetches the correct VPN HOST and the Cisco AnyConnect webvpn cookie.

Installation for CLI usage

Simply run pip install --upgrade git+https://git.snas.black-burn.ch/FHNW/openconnect-ms-auth to install the package globally. Then the "ocma" command should be available. Try it out by typing ocma -h.

Password character limitations

There are some special characters, that might make your life difficult and are best left out of your password:

• $: Most often in bash, this will try and reference a variable, do not use it
• !: Most often in bash, this will repeat the last command

Example CLI usage

Replace [username] and [password] with your own information. If you have your account secured with a TOTP MFA, provide the -m flag with the TOTP secret as the value.

Example of a TOTP url: otpauth://totp/FHNW%3Aelon.musk%40students.fhnw.ch?secret=NBSWY3DPEB3W64TMMQ&issuer=Microsoft The secret in this case would be NBSWY3DPEB3W64TMMQ. This needs to be provided as an input.

eval $( ocma -u [username] -p [password] -m [mfa_secret] --print-to-stdout );
[ -n $VPN_COOKIE ] && echo $VPN_COOKIE | sudo openconnect --cookie-on-stdin $VPN_HOST

Example usage in a Python project
