I'm trying to speed up the loading of all the groups->users mapping. some of the sAMAccountName have the periods in it which are getting rejected because of the periods. We're just going to have to make a separate uuid to real lookup pgsql or spanner table for humans I think for the admin ui side of things. I've got the group names being stored with uuidv5 values, but we can convert them on the fly in the admin tool.
