We've been running 4.2 on Windows for a while and we're testing ACS 5.1. In 4.2 there was the ability to create internal users and have them auth to an external source such as an RSA SecurID server, I haven't been able to do this in 5.1 successfully. Does anyone know if you can create internal users and have them auth via RSA SecurID?
If it's not possible is there any way to segregate external users into groups to limit access?
