When Zimbra proxy is configured, the Zimbra proxy config performs keyword substitution as necessary with values from the ZCS LDAP configuration and localconfig.
If changes are required after the Zimbra Proxy is set up, you modify the Zimbra LDAP attributes or localconfig values, and run
zmconfigd to generate the updated Zimbra Proxy configuration. The Zimbra proxy configuration file is in
/opt/zimbra/conf/nginx.conf. The nginx.conf includes the main config, memcache config, mail config, and web config files.
