I just spent a bit puzzling over "login_trusted_networks". My problem was using "10.1.2/24" instead of "10.1.2.0/24".

Here are some things I looked for during troubleshooting that didn't pan out:

(1) No messages printed to syslog. (2) Search for "login_trusted_networks" on the Wiki (wiki2) failed. (3) Comments in example config file didn't specify expected format.

Anyway, it works now. <shrug>
