Adds IP based authentication

[webermax]

Adds the possibility to authenticate users based on their IP address. This is especially useful for intranet solutions.

Definitely a neat plugin. Haven't tested it, but looking at the code I saw you misspelled a word in config.php on line 24: "identifie" ... I guess this shall be "identified"

Thx, I fixed it.

The IP auth plugin is a modification of the auth passthrough plugin.

You're welcome!

Und schöne Grüße nach München :D

@webermax thanks for taking the time to write a plugin. I have a couple questions about it:

• What would be the use case for the plugin? You seem to accept a couple arguments from the URL parameters ($_GET), but there seems to be very little checking on its validity. There's also no configuration parameters for what ip ranges or such would be acceptable.
• Seems like I could get in as an administrator by simple passing ?token=admin in the URL. Is that correct?
• You have a configuration option to enable client SSO, but you don't seem to check to see if it's enabled before signing in clients.
