So certificate planning is a must. Now, let's look at a list of some of the things you need to keep in mind when requesting certificates:.
All certificates must be signed using a signing algorithm supported by the operating system. Skype for Business Server supports the SHA-1 and SHA-2 suite of digest sizes , , and bit , and meets or exceeds the operating system requirements.
Encryption key lengths of , , and are supported. Key lengths of and greater are recommended. The default digest, or hash signing, algorithm is RSA. That's a lot to think about, and there are a variety of comfort levels with requesting certificates from a CA.
We'll give you some further guidance below to make your planning as painless as possible. You'll need certificates for most of your internal servers, and most likely, you'll get them from an internal CA that's a CA located in your domain. If you want to, you can request these certificates from an external CA one located on the Internet. If you're wondering what public CA you should go to, you can check out the Unified Communications certificate partners list.
You're also going to need certificates when Skype for Business Server communicates with other applications and servers, such as Microsoft Exchange Server. This will, obviously, need to be a certificate that these other apps and servers can use in a supported way.
Skype for Business Server and other Microsoft products support the Open Authorization OAuth protocol for server-to-server authentication and authorization. If you're interested in this, we have an additional planning article for OAuth and Skype for Business Server Skype for Business Server also includes support for without requiring certificates signed using the SHA cryptographic hash function. To keep things straightforward, we've put the certificate requirements for Standard Edition servers, Front End pools, and other roles, into the following tables, with the fictional contoso.
These are all standard web server certificates, with private keys that are non-exportable. Some additional things to note:. Server enhanced key usage EKU is automatically configured when you use the certificate wizard to request certificates.
As per the sample names below, if you've configured sipinternal. Your Edge internal interface will typically use a private certificate issued by your internal CA, but if you'd prefer, you can use a public certificate for this as well, if it's from a trusted CA. If you're deploying mobility and you're supporting automatic discovery for mobile clients, you're going to need to include some additional subject alternate name entries on your certificates to support the secure connections from the mobile clients.
This is where a little pre-planning is good, but sometimes you've deployed Skype for Business Server without intending to deploy mobility, and that comes up later when you already have certificates in your environment. Reissuing them via an internal CA is typically pretty easy, but with public certificates from a public CA, that can be a little more pricy. The Plan for Mobility article has more information on this. Skype for Business Server can use the same file share for all file storage.
You do need to keep the following in mind:. We recommend a shared cluster for the file share. If you're already using one, you should cluster Windows Server or higher versions. Why the latest Windows? Older versions may not have the right permissions to enable all features.
You can use Cluster Administrator to create the file shares. See this support article How to create file shares on a cluster for more details. You should know that using network attached storage NAS as a file share isn't supported, so use one of the options listed above. This support limitation is caused by the variable design of NAS devices that have to provide file system adaptability to the Windows Server-based computer that accesses the devices' shared file system.
