Ok i just can't fugure it out. Now i have this in my .htaccess:

AuthType Basic
AuthName "Formula Student Wiki"
AuthUserFile /home/formulas/.htpasswd
#Require valid-user
[download]

So no requiring a valid user. Now i have this in my code:

sub requestLogin
{
  if (($ENV{'REMOTE_USER'}) || ($ENV{'AUTH_USER'}))
  {
    message ('info', "Logged in.");
  }
  else
  {
    print <<EOF;
Status: 401 Authorization Required
WWW-Authenticate: Basic realm="Formula Student Wiki"
Connection: close
Content-type: text/plain

Login failed.
EOF
  }
}

Now my browser asks me for credentials 3 times, i enter them correctly but it still fails and i get the "Login Failed" message.

Since it's asking 3 times, apache must be doing that so i don't see why it fails. If i uncomment the require valid-user, everything works.

In your WWW-Authenticate header, I think you need a semicolon right after Basic.
