Hello,
I've just installed iRedMail: postfix, roundcube, mysql, clamav, spamassassin. All seems to work fine.
I've encountered only a problem: when I try to reach the page https://my_site_name/awstats.awstats.pl, the web browser ask me for a username/password.
If I try to fillthe fields with root credentials, it don't authorize me:
"Authorization Required
This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required."

File awstats.conf contains:
AllowAccessFromWebToAuthenticatedUsersOnly=0
AllowAccessFromWebToFollowingAuthenticatedUsersOnly=""

So I don't understand why I cannot log into AWSTAT.

How is wrong?
What credentials have I to use?

Thank you in advance
