I have attribute flows for AD groups to the FIM DB which worked under RC1 U3 but don't seem to work under RTM, now get "failed creation via web services" - under the detail the attribute membershipaddworkflow errors with "The specified attribute value does not satisfy the regular expression" Did the FIM requirements for the attribute membership add workflow change? I'm trying to set to "none". Thanks.

D'oh. Attribute is case sensitive. "None" works, "none" does not.
