Hi,

looks like an attempt to perform authentication in a subrequest.
Please provide your HTTPD configuration and I may be able to tell if that is wrong or if there is bug.

sure we have a conf file within conf.d which looks like this:

<Directory /xxx/xxx/xxx/xxx/xxx>
Options +ExecCGI -Indexes +MultiViews
AuthName "Control"
AuthType GSSAPI
GssapiBasicAuth On
GssapiLocalName on

Require valid-user

ErrorDocument 401 /control/error_401.htm

RewriteCond  %{HTTP_USER_AGENT}  Mobile [OR]
RewriteCond  %{HTTP_USER_AGENT}  iPhone [OR]
RewriteCond  %{HTTP_USER_AGENT}  iPad
RewriteRule ^$  /control/mobile.html

<Directory /xxx/xxx/xxx/xxx/xxx>
require user xxx

Does this happen with all clients, or just with some?
