Cannot modify or delete user roles.

Products

• VMware Smart Assurance

Issue/Introduction

• Cannot make any changes to the role, for example, give access rights to templates etc. When clicking 'save' the action is acknowledged, but when opening the role again,  nothing has been saved/changed. Also the delete is acknowledged, but the role is not removed.
• Saving changes to role causes role to be 'not specified' and all permissions set to 'no access'.

Environment

Watch4net/MnR - 7.X.X

Cause

This issue will be seen when there is a large number of users in that particular environment.

In catalina.log you will see this below error;

INFO: More than the maximum number of request parameters (GET plus POST) for a single request ([10,000]) were detected. Any parameters beyond this limit have been ignored. To change this limit, set the maxParameterCount attribute on the Connector.

Resolution

Add this parameter  "maxParameterCount" and the value to this in /<APG base dir>/Web-Servers/Tomcat/Default/conf/server.xml as shown below in the Frontend host, restart tomcat and observe the behavior.
