A third item you will need to be aware of is the usage of Hesiod clusters to control login permissions. This is managed in the same way that Solaris login permissions are managed – you will need to add a record to the Hesiod database, effectively “clustering” the new Realm Linux machine. The Hesiod information can be overridden through the use of local accounts or inserting user ID's into the /etc/users.local and /etc/hosers.local, just as with the Solaris kit.
