OAuth misbehaving?

[Walter Lapchynski]

I'm trying to set up OfflineIMAP for the first time based on the advice
of a blog I've found elsewhere. Unfortunately, there's several problems
with the suggested configuration which I've managed to fix, I believe.

Now I'm struggling with a more fundamental issue. Though my remote
is set with auth_mechanisms = XAUTH2 and no others, when I start
offlineimap, it asks for a password. What am I missing now?

For what it's worth, this is 6.5.4-2 on Ubuntu 14.04.
