[Moin-user] Sharing user authentication between wikis

[Matthew Brett]

Hi,

Sorry if I have missed this, but I am trying to find a way of sharing
user authentication between wikis on a wiki farm, here:

http://imaging.mrc-cbu.cam.ac.uk

I am already sharing the user database between wikis, but I wanted to
work out a nice automated way of taking all the users included on a
group page for one wiki:

http://imaging.mrc-cbu.cam.ac.uk/imaging/CbuGroup

and using this set of users as authorized users on the other wikis on
the wiki farm.

Is there any easy way to do this?  Can anyone point me in a good
direction to start writing an appropriate macro if that is the only
way to do it?

Thanks a lot,

Matthew
