	      eurephiadm  config  file and all configuration parameters in the database. The config command is used to set or delete configuration
	      parameters in the database.

       useradmin
	      This provides access to the eurephiadm users and eurephiadm usercerts commands, which is used to create or delete user accounts  and
	      link the user accounts together with a certificate and a firewall access profile.
