Optional: Create an LRS Administrator Group in Active Directory

Each LRS client that joins the domain can be fully managed by a domain user with local administrator rights on the LRS appliance PC. Therefore, you can create a dedicated administrators’ group in Active Directory and give this group administrative rights during set up of the new LRS machine.

Conferencing Policy for the LRS Account

The conferencing policy assigned to the LRS account must have certain characteristics. Most of the time, the LRS client joins a scheduled meeting, and therefore the conferencing policy of the meeting organizer will affect the conference. However, in Lync Server 2013, certain capabilities depend on the participant’s configuration. For example, if the participant’s policy allows a maximum video resolution of 1080p, the participants will experience this higher resolution video capability in the conference even if the organizer’s policy doesn’t allow it. The following table describes several such settings which you should be aware of when setting up conferencing policies for LRS accounts in your organization.

TRUE

Must be TRUE for LRS to ensure multi-view video streams

*   For information about bandwidth planning, see Network Bandwidth Requirements for Media Traffic at http://technet.microsoft.com/en-us/library/jj688118(v=ocs.15).aspx.

Note:

If the LRS client tries to join a scheduled meeting organized by a user who is homed on a Lync Server 2010 pool, the meeting organizer’s conferencing policy could prevent the LRS client from performing collaboration.  

Meeting Authentication

LRS prompts users for authentication when they use the meeting join link to join a restricted meeting; for example, a meeting for which meeting lobby options have been configured in Outlook. This setting is always on for customized meetings, and users are always prompted. However, for unrestricted meetings, users can join the meeting without authentication.

The following cmdlet enables administrators to require authentication for all meetings, including unrestricted meetings:

Set-CsMeetingConfiguration –RequireRoomSystemsAuthorization $TRUE

By default, RequireRoomSystemsAuthorization is FALSE.
