Creating Roles to Follow Organizational Structure

Often, the administrators within an organization are placed into a hierarchy in which subordinate administrators must assign rights independently of ranking administrators. In this case, it is useful to have one role that represents the rights assigned by higher-level administrators and to allow the subordinate administrators to create and manage their own roles.

Restricting Roles

Restrictions allow administrators to limit the scope of a role. A role only grants rights to those users that satisfy the role's restrictions. Using restricted roles results in users with dynamic rights that change based on the time of day or network address of the client.

For step-by-step instructions on how to create network and time restrictions on a role, refer to "Active Directory Role Restrictions (on page 165)" or "eDirectory Role Restrictions (on page 179, "Role Restrictions" on page 178)" sections.

Role Time Restrictions

Administrators can place time restrictions on LOM roles. Users are granted the rights specified for the LOM devices listed in the role, only if they are members of the role and meet the time restrictions for that role.

LOM devices use local host time to enforce time restrictions. If the LOM device clock is not set, the role time restriction fails unless no time restrictions are specified on the role.

Role-based time restrictions can only be satisfied if the time is set on the LOM device. The time is normally set when the host is booted, and it is maintained by running the agents in the host operating system, which allows the LOM device to compensate for leap year and minimize clock drift with respect to the host. Events, such as unexpected power loss or flashing LOM firmware, can cause the LOM device clock to not be set. Also, the host time must be correct for the LOM device to preserve time across firmware flashes.
