Hi Tom,

Grouper does membership mapping against a row in grouper_members. You can change the subject id there and all the group memberships / privileges still work because they map to a group using the member uuid.

There is a Member.setSubjectId method which allows GrouperSystem to do this change via the API.

I'm having an issue with changing the underlying name that Grouper is
using to identify a user. We have an attribute called OfficialName that
we want to use as the unique identifier in Grouper. Changing this value,
as might happen if someone has a legal name change, seems to be
problematic for Grouper. It recognizes the change if you do another
search, but if you try to list members in a group where one of the names
has been changed, Grouper spits back a Runtime Exception.

Anyone else dealt with this at all? How do you deal with a changing id in
your implementation?
