[Mailman-Users] Error: You are not authorized to create new mailing lists

[Sean Kirkpatrick]

Just installed Mailman 2.1.1 and get the following error when trying to
create a new list.

Error: You are not authorized to create new mailing lists

The authentication password that I'm using is the same one as let's me
administer mailman itself. 

I've seen nothing in the FAQ that covers this, and I'm sure I've done
something silly. 

Any clues?
