Description

RBAC enables administrators to delegate control of specific management tasks in Skype for Business Server. For example, instead of granting your organization's help desk full administrator privileges you can give these employees very specific rights: the right to manage only user accounts; the right to manage only Enterprise Voice components and the right to manage only archiving and Archiving Server. In addition, these rights can be limited in scope: someone can be given the right to manage Enterprise Voice, but only in the Redmond site; someone else can be given the right to manage users, but only if those user accounts are in the Finance organizational unit (OU).

The Skype for Business Server implementation of RBAC is based on two key elements: Active Directory security groups and Windows PowerShell cmdlets. When you install Skype for Business Server, a number of universal security groups, such as CsAdministrator, CsArchivingAdministrator and CsViewOnlyAdministrator, are created for you. These universal security groups have a one-to-one correspondence with RBAC roles, which means that any user who is in the CsArchivingAdministrator security group has all of the rights granted to the CsArchivingAdministrator RBAC role. In turn, the rights granted to an RBAC role are based on the cmdlets assigned to that role (cmdlets can be assigned to multiple RBAC roles). For example, suppose a role has been assigned the following cmdlets:

Get-ArchivingPolicy

Grant-ArchivingPolicy

New-ArchivingPolicy

Remove-ArchivingPolicy

Set-ArchivingPolicy

Get-ArchivingConfiguration

New-ArchivingConfiguration

Remove-ArchivingConfiguration

Set-ArchivingConfiguration

Get-CsUser

Export-CsArchivingData

Get-CsComputer

Get-CsPool

Get-CsService

Get-CsSite

The preceding list represents the only cmdlets that a user assigned a hypothetical RBAC role is allowed to run in a remote session of the Windows PowerShell command-line interface. If the user tries to run the Disable-CsUser cmdlet that command will fail because users assigned the hypothetical role do not have the right to run the Disable-CsUser cmdlet. This applies to the Skype for Business Server Control Panel as well. For example, an Archiving Administrator cannot disable a user by using the Skype for Business Server Control Panel because the Skype for Business Server Control Panel abides by RBAC roles. (Any time you run a command in Skype for Business Server Control Panel you are actually calling a Windows PowerShell cmdlet.) If you are not allowed to run the Disable-CsUser cmdlet, it won't matter whether you directly run that cmdlet from Windows PowerShell or if you indirectly run the cmdlet from within the Skype for Business Server Control Panel: the command will fail.)

Note that RBAC applies only to remote management. If you are logged on to a computer running Skype for Business Server and you open the Lync Server Management Shell, RBAC roles will not be enforced. Instead, security is enforced primarily through the security groups RTCUniversalServerAdmins; RTCUniversalUserAdmins and RTCUniversalReadOnlyAdmins.

When you install Skype for Business Server, Setup creates several built-in RBAC roles that cover common administrative areas such as voice administration, user management and Response Group administration. These built-in roles cannot be modified in any way: you cannot add or remove cmdlets to the roles and you cannot delete these roles. (Any attempt to delete a built-in role will result in an error message.) However, you can use the built-in roles to create custom RBAC roles. These custom roles can then be modified by changing the administrative scopes; for example, you can limit the role to managing user accounts with a particular Active Directory OU.

Any custom roles you create can be deleted by using the Remove-CsAdminRole cmdlet. Note that the Remove-CsAdminRole cmdlet will not delete the Active Directory security group that corresponds to the custom role, nor will it remove any of the members who have been assigned to the group. Instead, the cmdlet simply ensures that this custom role cannot be used to delegate control of Skype for Business Server.

When you delete an RBAC role, Windows PowerShell will respond by asking if you are sure you want to delete this role; if you do not respond to this prompt (or do not respond by saying Yes) then the role will not be deleted. To avoid these confirmation prompts, use the Confirm parameter and set the parameter value to $False:

Remove-CsAdminRole RedmondAdministrators -Confirm:$False

Examples

-------------------------- Example 1 ------------------------

Remove-CsAdminRole -Identity "RedmondHelpDesk"

The command shown in Example 1 deletes the RBAC role with the Identity RedmondHelpDesk.

-------------------------- Example 2 ------------------------

Remove-CsAdminRole -Filter "*Redmond*"

Example 2 deletes all of the RBAC roles that have the string value "Redmond" somewhere in their Identity.

-------------------------- Example 3 ------------------------

Get-CsAdminRole | Where-Object {$_.IsStandardRole -eq $False} | Remove-CsAdminRole

In Example 3, the command deletes all of the custom RBAC roles that have been created for use in your organization. To do this, the command first calls the Get-CsAdminRole cmdlet without any parameters; that returns a collection of the RBAC roles. This collection is then piped to the Where-Object cmdlet, which selects only those roles where the IsStandardRole property is equal to False. By definition, any role meeting that criterion is a custom role. In turn, those custom roles are piped to and deleted by, the Remove-CsAdminRole cmdlet.

Parameters
