rpxnow vs dotnetopenid, What do you think ?

Question

I read a couple of posts about this but i was really more confused about what shall i use or what would be better, or even am i missing some other solutions ?

Please advice, Thanks

Answer 1

DotNetOpenID works great, and you'll have a decent amount of control over the process. RPXNow charges you if you want to customize the login screen or synchronize profile data. I would rather not be tied to a company for OpenID.

Answer 2

The problem with using a library like DotNetOpenAuth or openid4java is that you still have to implement a lot of additional security. For example, Yahoo requires some additional XML files to properly work without warnings.

RPXNow is free or cheap. And if you you implement it correctly you won't be locked in to them in case you decide to switch.

Answer 3

But with RPX, when your use gets to the OpenId provider, the provider reports the RPX URL instead of yours. I would think that would make end users reluctant to authenticate.
