A way for admins to edit users' external IDs

[Falco]

@sudoman

However the issue here isn’t updating the user name of someone who logs in with an External ID of ‘bob’, but allowing Bob to log into the same account with the a new External ID of ‘alice’. In order to do so, it looks like the External ID of Bob’s account needs to be changed from ‘bob’ to ‘alice’.

Why are you updating the external_id? The external_id is supposed to be a immutable identifier of the user in the auth source, like the ID column from the database or a long UUID, or anything stable.

From the documentation:

@sam

external_id is any string unique to the user that will never change, even if their email, name, etc change. The suggested value is your database’s ‘id’ row number.
