SMA is asking for credentials and whenever user enter the credentials, it is asking again. User has also observed few error in PegaRULES log file.

Error Messages the attempt to distribute application "prsysmgmt" while the application is running.

Steps to Reproduce

Launch SMA with Pega 7.1.7.

Root Cause

User is accessing the System Management Application in Process Commander must be assigned the role PegaDiagnosticUser.

If the user does not have this role, user will be challenged for authentication when attempts to access the System Management Application from Process Commander.

By default, the deployment configuration for Process Commander assigns the PegaDiagnosticUser role to administrative users.

To restrict access to the System Management Application, use the application server tools, to assign the PegaDiagnosticUser role to any other users who must be able to access the System Management Application.


The role PegaDiagnosticUser is associated with the System Management Application (SMA) through a securityconstraint element on the DiagnosticData Servlet defined in the prweb.war application’s web.xml file.
