The mailing list for listmasters using Sympa

["antonelli@cnaf" <address@concealed>]

Dear all,

we have a Sympa 6.2.56 multi domain installation with CAS/LDAP 
authentication/authorization so we allow access only to users of our 
Institution (apart from open ML/archives). The question is related to 
how to configure a scenario for subscription to a mailing list after 
authentication.

It seems to me that the "auth" part of subscription default scenarii 
refers to authorization which means "you ask for a subscription -> you 
receive a mail saying you requested it ->  you accept it by clicking on 
a link and authorize the subscription".

Is there a default scenario or a way to configure one to make a 
subscription possible only after the user has authenticated him/herself?

Thank you
regards
Stefano
