Certificate Requirements for Mobile Clients

In addition to the certificate requirements for Lync Server 2010 described in Certificate Infrastructure Requirements, if you choose to support automatic discovery for Microsoft Lync 2010 mobile clients, you need to include certain subject alternative name (SAN) entries on certificates to support secure connections from the mobile clients. For details, see Certificate Requirements for Mobility.

Aside from the requirements for installing and configuring certificates on your servers, there are no additional requirements for installing certificates on mobile clients.

Requirements for Automatic Discovery

During the planning phase, you need to decide whether you want to support automatic discovery for Lync mobile clients or use your existing Web Service URLs. To use the automatic discovery feature, you need to configure DNS and create new web publishing rules to support the feature. For details, see Defining Your Mobility Requirements and Technical Requirements for Mobility.

Sign-in Requirements for Mobile Clients

When deploying mobile access to your users, the sign-in information you will need to communicate to your users depends on the following factors:

• The Lync mobile client
  
• Whether Lync Server 2010 is configured to use automatic discovery for mobile clients
  
• Whether users are hosted on an on-premises Lync server or Office 365 and/or Lync Online
  
• Whether a user’s SIP address is the same as the user’s user principal name (UPN)
  

The next sections summarize the sign-in fields required for each mobile client.

 

1. Sign-in requirements for Windows Phone, iPhone, iPad, and Android
   

   The following table describes the sign-in fields required for Microsoft Lync 2010 for Windows Phone, Microsoft Lync 2010 for iPhone, Microsoft Lync 2010 for iPad, and Microsoft Lync 2010 for Android users. If you have not configured automatic discovery for mobile clients, users will also need to turn off Auto-detect server and type the internal and external discovery addresses.
   

   Note:
   The Sign-in address and Password fields are available on the sign-in screen. Users can access the User name, Auto-detect server, internal discovery address, and external discovery address fields by selecting additional sign-in settings from the sign-in screen.
