I have "WWW-Authenticate: Negotiate" working on IIS 5.1 and php 5.2 in isapi mode but I can not figure out how to determine the user name that was used. The When I decode $_SERVER['HTTP_AUTHORIZATION'] I get NTLMSSP: $_Server[base64_decode(substr($_SERVER['HTTP_AUTHORIZATION'],10))] I have the same issue with WWW-Authenticate: NTLM authentication Thanks, Aspen -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
