We need to have an option for a user to change their username. This is critical for auto-generated login ids (from the internal store, etc.)
Seems like this would be tricky as we currently have a unique constraint on login.
This is definitely an issue which should be revisited. Are people actually complaining about their userids? This something that we might want to think about for the next cut of RHN?
This is definitely something that we should look into. Don't really know how big of a problem it is, so guess that we should find that out first.
