To use SSO with Apache TomEE+
To make SSO work with the way the Apache TomEE+ server handles iconmail attachments and page history, use the following setting:
<context-param id="ContextParam_#">
<param-name>ematrix.server.domain</param-name>
<param-value>DOMAIN_NAME
</param-value>
</context-param>
This setting is required only for the Apache TomEE+/SSO environment.
