Hi, I had the same problem with mod_auth_kerb. > RewriteEngine On > RewriteCond %{LA-U:REMOTE_USER} (.+) > RewriteRule .* - [E=RU:%1] > RequestHeader set REMOTE_USER %{RU}e My solution was to change the RewriteRule to: RewriteRule .* - [E=RU:%1,NS] >From Apache documentation: 'nosubreq|NS' (used only if no internal sub-request) This flag forces the rewriting engine to skip a rewriting rule if the current request is an internal sub-request %{LA-U:REMOTE_USER} is doing such an internal sub-request. And with the NS-flag it isn't be rewritten to it self again and again...
