How do I change administrative control in LDAP?

To change the special system administrator assignment, go to the ROOT.xml configuration file at $INSTALLDIR/tomcat/conf/Catalina/localhost/ROOT.xml. Near the bottom of that file is a line:

   <Parameter description="The name of the Code Collaborator system administrator who is always allowed to log in." name="system-administrator" override="false" value="admin"/>

Change the value to the login name you'd like to set the account to:

   <Parameter description="The name of the Code Collaborator system administrator who is always allowed to log in." name="system-administrator" override="false" value="XXXXXXXXXXXX"/>

where XXXXXXXXXXXX is the login name of the System Administrator. Then restart the service.
