LightOpenID - Provider issued an assertion for an

Question

This is the error I get after logging into Stack with my LightOpenID provider script.

The OpenID Provider issued an assertion for an Identifier whose discovery information did not match.

Assertion endpoint info: 
ClaimedIdentifier: http ://sub.mydomain.net/?cgillis 
ProviderLocalIdentifier: http ://sub.mydomain.net/?cgillis 
ProviderEndpoint: http ://sub.mydomain.net/ 
OpenID version: 2.0 Service Type URIs: 

Discovered endpoint info: [{ 
ClaimedIdentifier: http ://specs.openid.net/auth/2.0/identifier_select        
ProviderLocalIdentifier: http ://specs.openid.net/auth/2.0/identifier_select    
ProviderEndpoint: http ://sub.mydomain.net/ 
OpenID version: 2.0 Service Type URIs: http ://specs.openid.net/auth/2.0/server },] 

Provider script: https://gist.github.com/1072612

I should note the provider has select_id set to true. Everything works if it's set to false.

Basically, the problem is that you set select_id = true for the identity urls. If you set it to false for only the urls returned by checkid(), it will work as expected.

See __construct() in example.php from the repository for an example on how can this problem be solved.
