Java GAE, openid4java fails while doing discovery on google, Permission Denied

[Rashmi Phatak]

I am using Openid4Java to implement Openid for my app on GAE. I am also using Shiro for security. The day before i had reached a stage where things were failing for credentials matching, i.e discovery, making auth request, getting claimed_id were all working. Yesterday all hell broke lose and since then discovery on Google is failing. things that i have verified:

• Yahoo is working fine (end to end)and
• Discovery for google is working fine on my local dev box(it ofcourse fails while returning to my localhost URL).
• The application on appengine has billing enabled so that internally Yadis can open socket connections.

I have tried the following discovery urls for Google:

• https://www.google.com/accounts/o8/id
• https://www.google.com/accounts/o8/ud (https://developers.google.com/accounts/docs/OpenID?hl=es-ES#endpoint)

A few interesting logs before the stack trace:

the relying party code is pretty similar to the SampleConsumer (part of openid4java) but is actually a patch on shiro(openid4j). It seems to be in accordance with Sample Consumer.

Seems to me that i am missing something basic here. Any pointers will really help.

This error message does not come from openid4java, try checking with
shiro.openid4j to see what the cause for this error is.

Its a limitation of the sockets on GAE. As of now have using an appengine friendly HTTPFetcher.
