newbie question - apache-win2K-authentication

Hi all --- I'm having some trouble getting basic authentication working. Either that or my privileges are screwed up, or something. I am running Apache on Windows 2000 and PHP4. I've searched newsgroups, this mailing list, various FAQs and the manual, I think my eyes are crossing. I've got a feeling either its so simple I can't see it, or its not possible. I'm hoping someone has a quick idea about what's going on. Here's my story: My authentication script is from this example. If I leave it as is, I can authenticate and I receive the error: malformed = header from script. Bad header=3DHTTP/1.0 401 Unauthorized: =e:/php/php.exe If I change the unauthorized header to this: header("Status: 401 Unauthorized"); I cannot authenticate, though the user id and password is correct. Thanks in advance ! Shari My script: if (!isset($PHP_AUTH_USER)) { // If empty, send header causing dialog box to appear header('WWW-Authenticate: Basic realm="securedf"'); header('HTTP/1.0 401 Unauthorized'); echo 'Authorization Required.'; exit; } // If not empty, display values for variables else { echo " <P>You have entered this username: $PHP_AUTH_USER<br> You have entered this password: $PHP_AUTH_PW<br> The authorization type is: $PHP_AUTH_TYPE</p> "; }
