Installing MDM v11.6 and MDM v11.5 on WebSphere Application Server v8.5.5.12 using IM GUI

When an attempt is made to install MDM v11.6.0.2 or below on WebSphere Application Server v8.5.5.12 using the Installation Manager GUI, certain exceptions are noticed in the WAS Config Panel and in the Panels that correspond to the MDM User Interfaces.  To overcome this exception and continue installation using IM GUI, the below steps have to be performed:
1. When the installation is on WAS ND, go to System Administration -> Deployment Manager -> Java And Process Management -> Process definition -> Java Virtual Machine -> Custom Properties
When the installation is on WAS Base, go to Servers -> Server Types -> WebSphere Application Servers -> <SERVER> -> Java And Process Management -> Process definition -> Java Virtual Machine -> Custom Properties
2. Add property com.ibm.ws.management.connector.soap.disableSOAPAuthCheck with value as true
3. Restart the Deployment Manager

Setting value for JVM Custom property com.ibm.ws.management.connector.soap.disableSOAPAuthCheck

This property can be removed from the JVM Custom properties and the server can be restarted after the Installation Manager completes extraction of MDM.

The other alternatives to proceed with installation of MDM v11.6.0.2 and below on WAS v8.5.5.12 are:
1. Install using silent mode by providing the inputs through a response file
2. Install MDM on a lower fixpack of WAS and upgrade WAS after MDM installation and configuration.
