Here is a patch to includes/User.php to allow password checking via a remote webserver. We're using it here to authenticate against our Kerberos server via a connection to an apache vhost on localhost running mod_auth_kerb, but I've generalized the code so it should work against any webserver you specify. To enable it, add something like the following to LocalSettings.php: $wgRemotePasswordCheck = true; $wgRemotePasswordServer = "localhost"; $wgRemotePasswordPort = 80; Patch: --- mediawiki-1.3.7/includes/User.php Thu Sep 23 11:41:57 2004 +++ wiki-bioterm/includes/User.php Tue Oct 26 17:32:04 2004 @@ -722,6 +722,7 @@ # Check to see if the given clear-text password is one of the accepted passwords function checkPassword( $password ) { + global $wgRemotePasswordCheck, $wgRemotePasswordServer, $wgRemotePasswordPort; $this->loadFromDatabase(); $ep = $this->encryptPassword( $password ); if ( 0 == strcmp( $ep, $this->mPassword ) ) { @@ -733,6 +734,24 @@ # Check for this with iconv $cp1252hash = $this->encryptPassword( iconv( 'UTF-8', 'WINDOWS-1252', $password ) ); if ( 0 == strcmp( $cp1252hash, $this->mPassword ) ) { + return true; + } + } + if ( $wgRemotePasswordCheck ) { + $lower = strtolower( $this->mName ); + $credentials = $lower .
