pfSense

There is no limit we are aware of specifically, the only way to find out would be to test it with one, two, three, etc.

It would likely vary based on the name since that blob there is a base64 encoded string of all the selected auth sources.

I see in your error output above you added 8 servers. I doubt that would work practically anyhow, since it would take so long to fail through all of them, the authentication would timeout in the meantime.

While we could handle this more gracefully, the underlying issue is a limitation in OpenVPN config file line lengths and not something we can solve per se.

PR has been merged. Thanks!
