The definition of the group in a user's registration form serves to define that a specific user who has access to the corporate portal of the public employee of the Generalitat can access EACAT with the same access credentials that they use for ATRI.
If the user who wants to register does not have access to ATRI, the option marked by default as local user, which is the usual group of EACAT, must be left selected, regardless of the type of entity in which they are registering.
