[2.1 scala] OpenID Simple Registration...

[Mike Bryant]

Hi all - I'm currently using the OpenID API with Play 2.1 and it's all working fine... as long as I use Google to log in. The problem is I really need an email from users, and I can't get attribute exchange working with some other major providers (Yahoo, MyOpenID). 

First of all, if anyone knows of any tricks to get this to work with attribute exchange as outlined in the Play docs I'd be very grateful. Is there a specific URI which most accept? I've already tried:

http://schema.openid.net/contact/email

http://openid.net/contact/internet/email

Secondly, I was looking into the Simple Registration extension; apparently this is what Stackoverflow use since attribute exchange is flaky (due to disagreements on the attribute urls.) Is SReg currently possible with the Play 2.1 libs? I've had a glance through the code and I couldn't see anything obviously pointing to it, and since I find OpenID pretty complex anyway I'm afraid of disappearing down a wormhole if I look into it any further.

Many thanks!

Mike
