Users and groups allow you to control access and permissions in vSphere. Users are individuals authorized to log into hosts or vCenter Server, and can be added, removed, or have their passwords and group memberships changed. Groups are sets of users that share common permissions, and users can belong to multiple groups to streamline permissions setup. Removing or modifying users and groups also removes any associated permissions.

2. AGENDA
• Creating a virtual machine
• Managing Users, Groups, Roles, and Permissions

3. Users and Groups
Defining users, groups, roles, and permissions lets
you control who has access to your vSphere
managed objects and what actions they can
perform.

4. Users

A user is an individual authorized to log in to a host or vCenter
Server.

If you log in to an ESX/ESXi host as root using the vSphere
Client, you can use the Users and Groups tab to perform
management activities for these users.

You can add users, remove users, change passwords, set group
membership, and configure permissions.

You can also use Active Directory to manage users and groups for
an ESX/ESXi host.

5. Groups

A group is a set of users that you manage through a
common set of permissions.

A user can be a member of more than one group, Using
groups can reduce the time it takes to set up your
permissions model.

6. Removing or Modifying users and groups:

When you remove users or groups, you also remove permissions
granted to those users or groups.

Modifying a user or group name causes the original name to
become invalid.
