I have select p for logins and extrep in the assigned user group. The error is U00000009 'LOGIN.RDW': Access Denied. This is also showing for LOGIN.RMS.
We just hit this on 12.3.2 HF1. We found for active jobs, even for a read only role, the UserGroup requires "Execute" for Login objects for this to work. Which seems odd for just viewing the report but it fixed the issue.
Just documenting for future reference as this thread is old.
