Require cas-attribute not work for rewrited url

[chrislywhkust]

require cas-attribute won't work for rewrite url

e.g.,

.htaccess

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [QSA,L]

It rewrite everything to index.php. If the directory is protected by require cas-attribute, Apache will deny the access.

The workaround is using SAMLValidate instead.

Following patch could help even not using SAMLValidate:
