request.getRemoteUser() gives null | tomcatAuthentication attribute on the AJP connector

Hi Team,

We are using JBoss EAP 7.4.0.GA and apache with LDAP authentication. After installation and configuration. When we are trying to access application it prompts for LDAP authentication, after passing ID and password, it gets logged in, but "request.getRemoteUser() gives null". We are using standalone-ha.xml.

Please help us to fix this issue, as we are stuck and not able to move it to production.
