The test would loop forever if authtype bit 0 wasn't set.

This looks like the correct fix. Daniel, please verify.
The problem was introduced in 915032ea02
There are probably many autobuilds around looping now (those
that do 'make test' anyway), so you autobuilders out there should
take a look and kill off some processes..
