It is recommended that users making administrative connections to the EMS server are not defined in both the EMS server’s user configuration file and externally through JAAS. Administrative users should only be defined in one place.
An exception is the default administrative user, admin, which is always defined locally by the EMS server. If the default administrative user is to be defined elsewhere and authenticated through JAAS, one can set an undisclosed password for the default administrative user in the EMS server's user configuration file (
users.conf) so that local authentication of the
admin user never succeeds, thus allowing JAAS to handle authentication.
