When logging in using OAuth as a standard user, any attempt to update salesforce fields using the Remote Access REST API fails with the following:

Salesforce is giving response 400 which means "Bad Request". The body of the response has "

{"message"=>"insufficient access rights on cross-reference id", "errorCode"=>"INSUFFICIENT_ACCESS"}

Updating works fine when logged in as a user with Administrator privileges.

Hi All,
