Hi,

When users log in to Salesforce via frontdoor.jsp (http://docs.releasenotes.salesforce.com/en-us/winter14/release-notes/security_frontdoorjsp.htm), they are unable to access Saleforce Canvas apps. 

The exact error is:

Oops, there was an error rendering Force.com Canvas application [Cavnas_App_Name].
Your browsing session has ended or is invalid. Please re-login to Salesforce.com again.

Everything else within Salesforce appears to be working fine, so we know the session is valid.

We have tried adding all OAuth scopes (including full and web) to the Canvas app, but still get the same error.

Any ideas?
