The mailing list for listmasters using Sympa

[address@concealed]

When I authenticate in Sympa's Web Interface with Internet Explorer  
(7), appears the following message:

-----------------------------------------------------
Sympa could not set a cookie for login.
Your should configure your browser to accept cookies.
-----------------------------------------------------

And then, when I go to another section in the Web, it makes me to  
authenticate again.
I tried to accept all cookies configuring the Web browser, but the  
problem is remaining.

However, the authentication in Mozilla Firefox works perfectly.

I'm using the version 5.4b.1 of Sympa.
Has anybody the same problem or knows how to solve it?

Thanks.

Adib.
