About target device access rights
When you assign access rights to a target device, any available session types may be selected, even
if the target device does not support them. For example, you may enable Video Viewer and virtual
media sessions to a target device that is attached to a CCM appliance, which does not support
virtual media. The target device access rights are not based on the valid type of connection to that
target device - the ability to establish a particular session type exists only when the target device
(through its managed appliance) supports it. Using the above example, if the target device that was
attached to the CCM appliance was later moved to a managed appliance that supported virtual
media sessions, the target device could then be accessed by that method.
Each access right is independent of other access rights. For example, you may enable virtual media
session access to a target device that supports it, but not enable KVM (Video Viewer) session
access to that target device. Since a virtual media session is launched from a KVM session, that
user would, in fact, not be able to open a virtual media session with that target device. The access
right only indicates that the user is allowed to perform the operation; it does not mean that the
operation can actually be performed.
How access rights can be assigned
There are several ways you may assign access rights.
• You may assign access control rights from a unit perspective. From this perspective, you select
one or more units, specify the users/user groups for which rights will be assigned, then allow/
deny the permission to perform the action for each user/user group. See
Unit Access Rights on
page 121.
• You may also assign access control rights from a unit group perspective. This is similar to
assigning access control rights for a unit, except all units that belong to the selected unit group
will be affected. See
Changing the name, members or access rights of a unit group on
page 175.
• You may also assign access control rights from a user perspective. You select a user account,
specify the units for which rights will be assigned, then indicate the permission to perform the
action (none, allow, deny or inherit) for each unit. See
User Access Rights on page 189.
• You may assign access control rights from a user group perspective. This is similar to
assigning access control rights for a user, except all users who are members of the selected user
group will be affected. See
User group access rights on page 194.
