Security Task and Security Role for DRM

In the User Security Setup window, I have Alternate/Modified Forms and Reports ID showing DEFAULTUSER. What else does a User need for access to DRM?

Please be sure that each User that needs access to DRM has the DEFAULTUSER Security Task in at least one Security Role that they are assigned to.

Note that the DEFAULTUSER Alternate/Modified Forms and Reports ID is different from the DEFAULTUSER Security Task.
