SSL Certificate Names

Site Logo

In a discussion about SSL certificates for Exchange servers the question of whether to include server names in the SSL certificate often comes up. However, that is not best practice. In addition to using as few certificates as possible, you should also use as few host names as possible.

This practice can save money. Many certificate providers charge a fee based on the number of host names you add to your certificate. As Rajith points out here this best practice is important for larger organizations to reduce costs, reduce administrative overheads, and because in larger scale environments services are configured with namespaces that resolve to load-balanced IP addresses and so on. In addition, using server names in URLs is going to cause problems for you with future migrations.

Since those issues apply to almost every Exchange Server environment, this is a topic worth covering in more detail. The host names you must include in your Exchange certificates are the host names used by client applications to connect to Exchange. Those services include:. Sticking to a simple scenario we will plan to use one namespace for all of the services.

Split DNS allows your internal clients to receive a different answer to their DNS lookups than an external client would receive. In effect you have your Exchange namespace in this example exchangedemo. Meanwhile you also have the Exchange namespace hosted on your public DNS servers, with records configured to point to external IP addresses.

So for the sake of simplicity I will use PowerShell to configure all of the services. Remember we are looking at a simple scenario of two servers in a single site as shown in the diagram above, so you will see me piping commands such as Get-OWAVirtualDirectory into other commands to administer multiple objects at the same time.

Note: If you have multiple servers in different sites then you may wish to configure servers individually instead of in bulk, as different sites may have different namespace requirements in your organization. To review the current configuration use Get-OutlookAnywhere. To configure the internal and external host names use Set-OutlookAnywhere. Note that in addition to setting the host names you must also explicitly set the SSL requirement for both internal and external clients default for internal is False, which is fine, but I am enforcing it in this example , and either a default authentication method or an external authentication method set to NTLM in this example.

The final configuration is the AutoDiscover service connection point. He works as a consultant, writer, and trainer specializing in Office and Exchange Server. Useful article, thanks — still helpful in ! Also, it may be semi-related to the issues the other comment-writer mentioned about errors they hit. I changed my Exchange access urls to be the same internally and externally mail. It turns out that SIUS uses autodiscover to find the appropriate urls to perform its work.

From my investigation, it also seems like other tools such as some spam checkers might do the same. The event viewer showed the unauthorized error in the logs for Exclaimer, as did running Test-OutlookWebServices PowerShell cmdlet from the Exchange server. It turns out that since Server , there is a security feature called Loopback Check, which prevents access to a server using its FQDN, from that server itself. It mentions UNCs specifically, but it applies here as well. Alternatively you could manually set the Exchange urls in your affected software.

I recently migrated from exchange to servers and after doing so, this certificate disappeared. I followed instructions to re-create the self signed certificate and published it. This crashed all my client connections! I went through the instructions again and created yet another certificate with server. This fixed the issue. The problem is this self signed certificate is now synced across all exchange servers.

Please advise. And the both servers ssl applied successfully and autodiscover is giving profile to outlook clients internal and external. When I run HCW it changes my default receive connector to use the internal server name fqdn.

So do I need another third party certificate for my exchange servers internal name to use with my default receive connector to accept messages from ?

I have a single server, on premise, Exchange server. Currently, I have just one domain running—domain. I would like to add a couple of additional domains to the server—domain1. I would also add additional zones to my internal DNS servers pointing the mail. My question, is if I would need to modify the certificate to reflect the new domains, so that users are able to send, and receive, externally, as well as connect to the server from any mobile devices.

Currently my SAN cert includes mail. Do I need to add mail. External clients e. Ok…so the additional domains do not need to be added to the SAN certificate—if I create an SRV record in original, and additional, domains public DNS zones, pointing to the primary domains autodiscover record? Short answer, yes. This was requested by security. I have made a simple addition to our Cert, we added oa. Issue is i am the only user on exchange that is getting the new URL.

Everyone else is getting the old one, positive they still function properly. Do you have an idea on why this would happen? Clients discover the URLs via Autodiscover. New profiles should pick up the new URL fine though. Not sure what security benefit your team sees in this change, but test the above conditions and you might just find you need to wait a little longer, or possibly start recreating Outlook profiles.

All my servers have the DNS suffix ad. Can I change the SCP to autodiscover. I am already using mail. Should be fine as long as your SSL certificate has the name on it.

Hi, I have few queries. Considering Exchange has only one Mailbox roles and rest all roles in the form of services. I have migrated over about mailboxes to exchange First thing to check is whether the clients are fully patched, as there are a number of compatibility issues that can arise for outdated Office builds.

FYI — my domain is domain. But I just got a cert error for the main domain. Any suggestions to block this security alert. Thanks for your help,. Any suggestions? If you enable this policy setting, you can select one or more of the following options to disable in the AutoDiscover feature. If you have reconfigured all your virtual directories and autodiscover SCP to mail. Non-domain joined devices e. Thanks for the quick reply Paul, Would this include a non-domain remote workstaion trying to link through Outlook Anywhere?

If so, should I have a public dns record for autodiscover? You can implement one or several of those. When i delete the secondary replication and start a Primary zone the internal DNS Server is authoritative but cannot resolve all the other external names. I ran the powershell command to update the Outlook Anywhere settings for a new server.

I made a typo. I found the error within hours and corrected it, but clients are still getting proxy errors that reference the typo.

How long does it take to get the erroneous virtual directory setting out of the system? In a multiple server environment though, setting multiple servers to have the same internal and external URL will break proxying wont it? No, proxying will work fine. That works fine as well.

Split DNS is used to differentiate internal and external name resolution. I have setup all the internal and external uris to be the same mail.

The Autodiscover SCP should point to a name that is resolvable internally. I have split dns and the external name i set for autodiscover resolves to the internal IP address of the exchange server i have just tried setingg up NAT loopback and changing the DNS to the external IP address but it still comes back with error on autodiscover when i change the autodiscover SCP to the external name.

If your AD is domain. All mailboxes are still on I moved a test mailbox to server, but the server setting in the outlook client did not change. Autodiscover is just Autodiscover. When I ran the get-outlookanywhere command it returned both servers. I want to keep the old server fully functional with the remote.

When I run the commands to set the host names how do I target just the new Exchange server? Will the commands only target the server that EMS is explicitly connected to?

Thanks in advance.

What is the SSL Certificate Common Name?

In a data center, a friendly name is a title given to an application file, certificate or other IT asset so that a human being can easily remember the name and perhaps even understand some basic information about the asset's purpose. Friendly names are assigned to complement unique identifiers that are comprised of numeric or alphanumeric code by default. For example, if an administrator creates a new VMware virtual disk and the disk is named Windows 8-f Please check the box if you want to proceed.

Avoiding Server Names in SSL Certificates for Exchange Server

Microsoft Exchange Server is one of the most widely-used and most popular server platforms in existence. Step 3 — In the sidebar menu on the left, select Servers and then select Certificates from the menu. Step 4 — On the certificates page, select your server from the drop-down menu. Step 6 — Type the friendly name for the certificate and click Next.

The certificate is valid only if the request hostname matches the certificate common name.

An SSL certificate is must be associated with one or more host names. Selecting the correct names is very important, because the certificate will be valid only if the request matches the host name or host names associated with the SSL certificate. The Common Name allows specifying a single entry either a wildcard or single-name , whereas the SAN extension supports multiple entries. At DNSimple we like to simplify your experience, therefore we hid the technical details and implementation behind a simple interface.
