Step 1: Configuring Roles

Configuring roles for users is a two-step process:

1.Create roles.

2.Assigning roles to users or groups.

Creating Roles

Use the roleadm command to create roles and assign them to users or UNIX groups. You must first add roles that do not already exist, and then assign users to those roles. The following shows the roleadm command syntax:

roleadm add role

[comments]

delete

role

modify

oldrolename newrolename

assign

user role

revoke

user [role]

list [user=username][role=rolename][sys]

The following is a list and brief description of the roleadm command arguments:

add Adds the role to the system list of roles in /etc/rbac/roles. delete Deletes the role from the system list of roles in /etc/rbac/roles.

modify Changes role names in all three role-related database files: /etc/rbac/roles, /etc/rbac/user_role, and /etc/rbac/role_auth.

assign Assigns a role to a user or group, and updates the /etc/rbac/user_role. revoke Revokes a role from a user or group, and removes the entry from

/etc/rbac/user_role.

list Lists the valid system roles (sys), or the user-to-role mappings.

NOTE: Refer to the roleadm(1m) manpage for more information.

The following are two examples of the roleadm command adding new roles:

#roleadm add UserOperator roleadm: added role UserOperator

#roleadm add NetworkOperator roleadm: added role NetworkOperator
