DotNetOpenAuth - Google Apps OpenID login failed, x is not a secure Identifier

We are testing an OpenID DotNetOpenAuth ASP.Net website on a subdomain named like test.xyz.com, and both http and https are enabled. We also enabled "requireSSL". We are getting this error when we try it with the Google Apps OpenID endpoint:

Login failed: Sorry. This site only accepts OpenIDs that are HTTPS-secured, but http://xyz.com/openid?id=102043883906843397279 is not a secure Identifier.

I'm not sure what we are doing wrong. Maybe I forgot to se开发者_运维知识库tup something?

Am I right if I say that http://xyz.com/openid?id=102043883906843397279 is just an ID, not a functionning link?

We simply disabled requireSSL in DotNetOpenAuth and it now works. Not yet sure of it's use. Carl
