basic authentication - explorer 7

[giampietro.berti]

Hello all,
i' ve got a problem with the apache basic authentication....only with
explorer 7.

From a link i must do a SSO with an application under basic

authentication.
- I can not use usersw@url
- i can't modify the application under basic auth.

I've tray to use everything (ajax - activeX - etc..)... nothing!
All is OK....but is necessary to modify the explorer level of
security :-(

Help me!
