at com.pega.pegarules.session.internal.mgmt.authentication.SchemePRExternal.getInstance(

Steps to Reproduce

Not Applicable

Root Cause

A defect or configuration issue in the operating environment : PRExternal scheme is being used for custom authentication, this option instructs PRPC to locate an authentication service data object in the PegaRULES database and to use the activities specified in that object rather than standard authentication processing

When the login activity is running it's running in an unauthenticated requestor context using the default AccessGroup used for unauthenticated users. This is the AccessGroup defined in the Data-Admin-Requestor.<SystemName>.Browser instance where <SystemName> is equal to the current system name. Check the landing page under System -> General -> Systems, Nodes and Requestors.  This will show the current system name plus what default AccessGroup your browser requestor type for the System Name is currently using.
Add the Role to that AccessGroup that will grant permission to open instances of the data tables classes. Then during the authentication this issue will not occur


Perform the following local-change: Add the right role to the AccessGroup that will grant permission to open the data table classes.
