Infopath\Sharepoint Rights

[Gailc]

Hi,

I have an InfoPath form published on a Sharepoint Portal Server. I have
access limited to the form based on the user roles in Infopath but I need to
limit access to the form on sharepoint. Here's what I need to accomplish --
even though a member from Group "A" in Infopath created the form I don't want
that member to be able to edit the form after it is published to a Sharepoint
server. Is this possible?

I assume it is possible but for some reason I cannot get this to work.
