Configuring User Accounts And Privileges; Types Of Users - Dell EMC PowerEdge VRTX User Manual

Configuring User Accounts and Privileges

You can set up user accounts with specific privileges (role-based authority) to manage your system with CMC and maintain system
security. By default, CMC is configured with a local administrator account. The default user name is rootand the password is
calvin. As an administrator, you can set up user accounts to allow other users to access the CMC.
You can set up a maximum of 16 local users, or use directory services such as Microsoft Active Directory or LDAP to set up additional
user accounts. Using a directory service provides a central location for managing authorized user accounts.
CMC supports role-based access to users with a set of associated privileges. The roles are administrator, operator, read-only, or
none. The role defines the maximum privileges available.

Types of Users

There are two types of users:
• CMC users or chassis users
• iDRAC users or server users (since the iDRAC resides on a server)
CMC and iDRAC users can be local or directory service users.
Except where a CMC user has Server Administrator privilege, privileges granted to a CMC user are not automatically transferred to
the same user on a server, because server users are created independently from CMC users. In other words, CMC Active Directory
users and iDRAC Active Directory users reside on two different branches in the Active Directory tree. To create a local server user,
the Configure Users must log in to the server directly. The Configure Users cannot create a server user from CMC or vice versa.
This rule protects the security and integrity of the servers.

Description
User can log in to CMC and view all the CMC data, but cannot add or modify data or execute
commands.
It is possible for a user to have other privileges without the CMC Login User privilege. This feature is
useful when a user is temporarily not allowed to login. When that user's CMC Login User privilege is
restored, the user retains all the other privileges previously granted.
User can add or change data that:
• Identifies the chassis, such as chassis name and chassis location.
• Is assigned specifically to the chassis, such as IP mode (static or DHCP), static IP address, static
gateway, and static subnet mask.
• Provides services to the chassis, such as date and time, firmware update, and CMC reset.
• Is associated with the chassis, such as slot name and slot priority. Although these properties apply to
the servers, they are strictly chassis properties relating to the slots rather than the servers
themselves. For this reason, slot names and slot priorities can be added or changed whether or not
servers are present in the slots.
When a server is moved to a different chassis, it inherits the slot name and priority assigned to the slot it
occupies in the new chassis. The previous slot name and priority remain with the previous chassis.
NOTE: CMC users with the Chassis Configuration Administrator privilege can configure power
settings. However, the Chassis Control Administrator privilege is required to perform chassis
power operations, including power on, power off, and power cycle.
