Well put, and I could not agree more.

What would be very helpful would be adding the necessary support to  
Mailman 2.2 and 3 so that it can be a relying party, and perhaps we  
can finally deprecate or kill off the stupid user passwords.

[Mailman-Users] [Mailman-Developers] openID enabled mailman

I don't understand what you're trying to do.  The whole point of open
ID is delegating authorization to a third party.  If you want, you can
provide that service as well, but once you've enabled OpenID, you
shouldn't need a password for Mailman.  In fact, the Mailman password
should be disabled, as it is certainly less secure than OpenID at this
point in time.

  I want to know if there's already an openID enabled version of
  mailman available

The OpenID project has OpenID-enabled Mailman lists, but according to
Brad Knowles in the process of adapting Mailman to OpenID they broke a
lot of other features, and integrating their changes is non-trivial.

Hi Stephen

Thanks for your reply.
W want to implement the OpenID Provider for the mailman set up we are
running on our servers.
The idea is to use OpenID with mailman to provide single sign on for our
other user accounts like our wiki etc.
Our focus is on providing Single Sign On but we do not want to delegate
authentication to a third party. Hence we want to implement OpenID provider
for our Mailman service. and OpenID relying party for our wiki etc.

Now for the OpenID provider we may choose to have new passwords or use the
mailman passwords. For ease of users, we want to use the mailman passwords
for the OpenID provider.

I hope I have conveyed what I am trying to do. I will be thankful for any
suggestions

Thanks
Malveeka

I don't think this is a good idea.  Mailman is designed to deliver
single messages to multiple parties, which it does very well, and to
manage member lists, which it does tolerably well for many purposes.
It is not designed to keep secrets.  You may not now particularly
care, but it could be very annoying later if you decide you want more
security and need to switch your system.

Better to put your provider in a separate place from Mailman, and have
Mailman rely on and trust only your provider.  You could do them on
the same host if necessary but in the long run you might want to have
the provider on a dedicated host, depending on how serious you become
about security.

  and OpenID relying partyOD for our wiki etc.
  
  Now for the OpenID provider we may choose to have new passwords or use the
  mailman passwords. For ease of users, we want to use the mailman passwords
  for the OpenID provider.

Again, Mailman is not very secure.  In the default configuration,
passwords are mailed out in cleartext over non-secure channels (and
even so-called secure mail is pretty tricky -- it's much easier to
secure a web application).  The passwords are also stored in the
clear.  This means that if you want to set up OpenID for existing
users by transferring their passwords, it should be possible (I don't
know how offhand, though).

I don't recommend that, either.  Normally, people don't care that much
as there's not much damage that can be done via a mailing list, except
spamming, and most lists have additional defenses against that.  But
you plan to rely on these passwords to secure multiple services,
making the value of cracking one that much higher.  I would ask my own
users to set new passwords in this situation.

Of course, all these issues depend on a lot of factors.  You may have
better security than the default for the Internet in place, or much
more careful users, etc.
