Multiple challenges to login

[Maria Sanchez]

We are having problems when accessing our sites. No matter which browser we use to access it always requests authentication twice.
We have an Apache web server (v.2.2) with mod_auth_radius 2.0 installed. And we have mounted a Jboss application using mod_jk module and protected access to it.

I am not able to find any information about this and this is becoming a big problem.

This is the configuration for radius.conf:

<Location />
AuthType Basic
AuthName "RADIUS authentication"
AuthBasicAuthoritative Off
AuthRadiusAuthoritative on
AuthRadiusCookieValid 0
AuthRadiusActive On
require valid-user
</Location>

I have been playing with the values of the cookies, I originally had it in 5 and changed it to 0 but didn't help.

Any ideas why this can be happening?

Thanks,
    Maria
