    We would like to use the student id attribute of our student users in LTI linked systems. To do so we need a context variable for student id which we can use in the Tool Provider Custom Parameters part of the LTI-setup. For a students username the variable is available and we would love to have something like for student id.

    This is because the student id is used as the primary identification attribute for our users across the various systems we use (and in our SIS).
