354 Chapter 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)
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.
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.
