Thank you Steve for your reply. I have created from scratch in mailman 3 all the lists that were on the old mailman 2 server. So now I would like to pre-populate Django users for all the moderators and owners by creating accounts using their University NET account name and linking them to their University email address (what I used for their owner/moderator address). Unfortunately, its not simple because their NET username is a short, up to 8 character, username whereas their email address is first.last@yu.edu. I have access to the university database which correlates both so I will be able to feed both to whatever script will do this. The university does use SSO for many applications and I was asked by upper management of the IT department to try and implement it here. I'm still trying to understand your reply to my SSO question from last week (my SSO knowledge is limited and I'll have to read up on Shibboleth, SAML, as well as Django) so for now I'm thinking to not use SSO so that I can get things started and then transition to SSO later. If you have any pointers as to where to read up on SSO, SAML, Shibboleth and also on Django please point me in the right direction.
