[Twisted-Python] PB and Woven authentication

[Justin Johnson]

I know there have been other posts on this topic, but I wasn't sure how
up-to-date they are.

I currently have a PB server that I connect to via the command line.  It
allows me to do tasks on wintel servers I manage.  I'm now trying to
create a web interface to that service using woven.

Below is what I'm currently doing for authentication.

First of all, am I doing things right below?  Any corrections or
suggestions for improvement?

Once that is correct, how do I hook this up to woven?  I was trying to
look through the Quotient code to figure it out, but there is so much
other stuff in there I'm having a hard time keeping it all straight.

Thanks much.
