[Mailman-Users] list admin passwords failing

[Iain Pople]

Hi,

I have noticed in the last couple of days that all my list admin 
passwords are failing. I.e. I can't login to my lists via the admin web 
interface. I've had a look through the logs and can't see anything 
strange there.

When I try and login the page just reloads with the password prompt again.

I am using mailman 2.1.5.

I have tried resetting the password from the command line, but this 
makes no difference.

Has anyone else experienced this? Where else can I look to debug this 
behaviour?

thanks, Iain.
