[squid-users] one website denies access

hi,

i have a standard config of squid.conf
and surfing to every public website on the world works good
except one!

http://www.gmp-navigator.com

normally, i surf with ntlm authentication (challenge and response)
so that i access.log there is first access denied because of
no username information and on the next step squid gets an username
and finally the user has access to the sites.

BUT, at the link above i only get a log entry for the first access
without a username. nothing more!

and so the site is forever denied.

can anybody explain & help me?

regards
Andrew
