[Zope] Why require "Manager" for changing Z SQL Method?

I'm using Zope 2.3.0 and ZOracleDA 2.2.0b1. Users are starting to take advantage of the Oracle connections, but have been frustrated because they are unable to change Z SQL Methods. (They just keep creating new ones.) I think I've determined that a user *must* have "Manager" role in order to edit a Z SQL Method. The setting of "Change Database Method" doesn't seem to matter. I even gave it to Anonymous and it wouldn't go. Does someone have a quicky patch/kludge to get around this for awhile? It's not immediately obvious to me how to bypass it. Thanks. --kyler
