A Python Tracker user posted this:

'There are so many bug trackers around, and it's a big hassle asking
someone to manage a site-specific username+password just to submit a bug
report.'

To that I add that being able to share logins (OpenID, Google ID,
whatever) makes integration of different services much easier, allowing
richer feature sets.

E.g., I'm integrating our Tracker to Rietveld and any advanced
interaction (simultaneous changes, synchronizing patches) would require
the user to authenticate twice.

I might have time to work on this, but I know next to nothing about
authentication and could use some guidance :)

BTW, the user himself didn't submit this ticket... because he'd need yet
another login ;)

See https://code.launchpad.net/~techtonik/roundup/openid for an almost
complete implementation :)

Hi Anatoly:

I see some patches to the roundup core in your openid work.
It looks like a number of them are already in the 1.5.1 release.

Are you interested in finishing the openid integration at:

  https://code.launchpad.net/~techtonik/roundup/openid

against the current roundup head and we can see how to get
that into roundup (preferred) or onto the wiki as an example
of adding an authentication provider?

We have a number of attempts to integrate other auth methods. This ticket 
can cover all of them. Some of the openid are more than a decade old and 
I suspect use an older openid version. However some work is being done on 
github auth.
