I have an OpenShift account and now I'm shown an "additional action needed" page on login. When i complete it and hit submit, it tells me that email already exists.
I'll see if we can get a fix pushed out for this today/ASAP. The issue currently occurs when you have multiple Red Hat accounts that use the same email address (or a sub-addressed version of the same email address, like "chris@gmail.com" and "chris+123@gmail.com".

Is this a special case for Google mail or do you assume foo+bar@example.domain is the same as foo@example.domain ? Why?
It's an abuse prevention mechanism. We do not permit users to have multiple OpenShift Online accounts. See 2.1 in the OpenShift Online terms of service: https://www.openshift.com/legal/terms.html
"You may not (or permit third parties to) create multiple accounts or otherwise access the Services in a manner that is intended to avoid Fees or to circumvent maximum capacity thresholds for the Services."
No, I don't think what google does is standard behavior (not trying to say anything bad about Google; I love Google). However, as far as I know, disallowing + is not a particularly good way of preventing abuse. I won't go as far as to say it semms like bad code but it is pretty close.
I think it is OK to make a special case for Gmail and Google mail but it is counterproductive to try to crown it as a de facto standard.
