Annotation of loncom/html/adm/help/tex/ForceIDChange.tex, revision 1.1
1.1 ! raeburn 1: \label{ForceIDChange}
! 2: Although the username is the principal unique identifier for a user in LON-CAPA, the student/employee ID
! 3: is a secondary identifier, which needs to be defined (and unique) for certain applications.
! 4:
! 5: The default is not to allow the student/employee ID for an existing user to be changed when
! 6: modifying a user's information in course, author or domain context.
! 7:
! 8: This default can be overridden by checking the ``Force change of existing ID'' checkbox. If that is
! 9: done the old ID will be replaced with the new ID. (Note: the new ID can not be blank; i.e., once an ID
! 10: has been set for a user, it can be changed to a different ID, but not set to be null).
! 11:
! 12: A side effect of updating a student/employee ID is that the database file used for the quick
! 13: look-up of uername for a specified student/employee ID will be updated. This can potentially impact
! 14: bubblesheet grading, if there is a possibility that student/employee IDs are not unique.
! 15:
! 16: However, there is no requirement to set a student/employee ID for a user, and you will not encounter
! 17: issues doing that unless you attempt bubblesheet grading or uploading scores from a csv file
! 18: containing IDs and points as column data. If either of those actions are likely to occur in courses
! 19: in your domain you should attempt to ensure that student/employee IDs are unique.
! 20:
! 21: Your domain may have been configured to automatically update student/employee IDs from an institutional
! 22: data source, and similarly, IDs may be retrieved (and set) automatically when creating a new user, if the
! 23: username is for an institutional user, and your domain has been configured to support that.
! 24:
! 25: Individual courses contain their own database files of class rosters, which include a copy of each student's ID. If a student/employee ID is changed by a Domain Coordinator, there is an option to propagate that change to the individual classlist database files for courses in which the student has a role that is currently active, or one that will become active in the future.
