Developers of Sympa

[address@concealed]

Hi,
I have two independant Sympa servers and I want to avoid two successive 
authentications while going from the first to the second by using the 
cookie authentication!
So after a first connexion (login-password)on the first sympa I go on 
the second but nothing happens, the system still needs another 
authentication!
Do I have to change something to the cookielib.pm or it can't work at 
all?
Thanks for any help!
