SSO fails when the vpn is off.

Hi,

We are setting up a SSO in ADFS for a partner compnay we use. If I use the vpn we are able to get in fine.

If I take the vpn off I asks the user to login using their UPN

Any ideas where i can look for this ?

Sounds like the normal behavior.

When connected externally, you get internet DNS resolution and you end up on the WAP instead of the ADFS. So you get Form Based Authentication.
When the VPN is on, you get the intranet DNS resolution and you end up on the ADFS. So you can get SSO because of the authentication policy.
