In the first start of eXo Platform, the Account Setup and Greetings! screens will appear by default. However, in some scenarios, these screens are not necessary, for example:
When you have an extension that declares sample users.
When you want to connect to an existing user directory.
To skip these screens, simply open the file:
$PLATFORM_TOMCAT_HOME/gatein/conf/configuration.properties (in Tomcat).
$PLATFORM_JBOSS_HOME/standalone/configuration/gatein/configuration.properties (in JBoss).
Then, change the default value from "false" into "true" and restart the server.
