Sympa allows to configure multiple authentication mechanisms, see the 
auth.conf documentation 
<http://www.sympa.org/manual/authentication#auth.conf>
You'll notice that there are two kinds of authentication methods 
supported : 1) the one (like 'database' or 'ldap') that require that the 
sympa collects the user password ; 2) the one (like 'generic_sso' and 
'cas') that are single sign-on services and where sympa does not collect 
the user password.

You'll note that you can configure 'regexp' and 'negative_regexp' 
extries in each auth.conf paragraph to skip some configuration mechanisms.

Sympa also provides a way to ignore some authorization scenarios, at any 
level (list, robot, host). All you have to do is create an empty file 
named d_read.public:ignore in your scenari/ directory.
However, the list owner still has the ability to customize a scenario, 
from the web interface...
