Working with NAC's Facebook registration for guest access, and discussing with some customers, some ideas come up...
I don't know if it's on the roadmap, but some customers asked me about to features they would like to see in the upcoming NAC releases:
1) Goggle Registration: Some customers user Google services for a lot of uses and would like to register guests with Google Auth.
2) Twitter Registration: As Google, some customers would like to see an option to register with Twitter.
3) Social Networks Sponsored guest registration: The customers involved in my last demo asked about the possibility of using social networking registration with sponsorship. In the user guide it shows as not allowed, but should be a good feature.
What do you think about it?
