A question about Number 5 i the extension page:
// This is not advised, because it will evaluate every visitor
// to the same wiki user 'Everybody'
$wgAuthRemoteuserUserName = "Everybody";
I tried to use this form and insert a substring called $username read from a cookie containing the username instead of "Everybody",
$wgAuthRemoteuserUserName = $username;
but it seems to evaluate to nothing and the user is not logged in.
When I echo the string read from the cookie it looks ok.
If i write the the same cookie value as a string, and run the function on it, the function to read the username and log in works fine. I tried a lot of other string operations on the value as a string, and it still works, but when I try to use the substring from the cookie it will not login. What is wrong?
