Changing UID breaks group associations

[agrieco]

If you change the UID of an existing user that is associated with groups already, the appropriate tables are no updated to ensure the new UID is a member of all the groups.

Steps to reproduce:

1. create a user
2. associate the user with a group (e.g. GROUPA)
3. change the user UID

At this point, the user will no longer be a member of GROUPA.

Hi thanks for reporting and yes this is to be expected atm because they are joined in the db using that id.
A better solution would be to join groups and user accounts by an independent ID that isnt exposed to the enduser.
Not a big change but i will have to put together some special migration code to handel existing databases.
