Log in as a user who has permissions to change the maps.
For each client, become superuser or assume an equivalent role.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
Notify your users of the changes.
Notification is required so that the users can also run the automount command as superuser on their own computers. Note that the automount command gathers information from the master map whenever it is run.
