[Building Sakai] Internal users being redirected to CAS login for Samigo Test Links

[Mustansar Mehmood]

Hi,
On our Sakai 10 installation users are being redirected to CAS login 
despite the fact their accounts are internal(Non CAs/Container login 
based).
Links generated for tests such as
https://myhost.edu/samigo-app/servlet/Login?id=xxxxxxx-6f24-45b8-80ba-xxxxxxxxxxxxxxx
Any ideas if there is a way to fix this?
Regards,
Mustansar
