Nortel Networks 4050 manual User rights and group membership, Managing system users and groups

354Chapter 8 Managing system users and groups

User rights and group membership

There are three groups of system users who routinely access the system for configuration and management:

•admin (administrator)

•certadmin (certificate administrator)

•oper (operator)

Note: There are two additional types of users with specialized

functions: boot and root. For more information, see “Accessing the Nortel SNAS 4050 cluster” on page 775.

Group membership dictates user rights, as shown in Table 68 on page 354. When a user is a member of more than one group, user rights accumulate. The admin user, who by default is a member of all three groups, therefore has the same user rights as granted to members in the certadmin and oper group, in addition to the specific user rights granted by the admin group membership. The most permissive user rights become the effective user rights when a user is a member of more than one group. For more information about default user groups and related access levels, see “Accessing the Nortel SNAS 4050 cluster” on page 775.
