Common Issues From Users With UC Browser With Certificate Problems

As an IT professional, you are dealing with both the administration and management side as well as addressing issues that users may be having in connecting to the system with a variety of different devices.

This can result in a lot of unusual phone calls and questions about error messages or problems with any UC browser with certificate combination. The good news is that the UCC or Unified Communications Certificate that is designed to work effectively with the Microsoft Exchange and Office Communications servers removes a lot of the issues that may have occurred if you have used a Wildcard or other SSL/TLS product in the past.

Most users don't realize they have a UC browser with certificate issue, they just see the unsecured website warning and immediately call into the in-house IT department. Some of the more savvy users may understand the issue if they read the information provided on the warning, but this will also be a factor of the browser they are using and how much information is provided.

This is most commonly found when users are trying to use the UC browser with a certificate from an old device. This is not just true with the UCC products it was also a very real issue with mobile devices and Wildcard SSL certificate options prior to the Windows Mobile version 6. These devices were equipped with a browser that was modified to work the device systems and therefore did not support the recognition of the Wildcards from any Certificate Authority (CA).

That issue has been resolved and is no longer an issue provided users have either upgraded their devices or are no longer using those old systems. As the UCC products are new and designed specifically to include the use with mobile devices the UC browser with certificate calls should be minimal if they happen at all.

It is also important to note that Comodo is recognized and trusted by 99.9% of browsers and devices. As we were also one of the few CAs initially approved by Microsoft to be vendors of the UCC product, we have the experience and the expertise to assist with any issues that may occur before, during and after the installation.

The Basic Information

The UCC works with more than just the Microsoft Exchange and Office Communications servers and can be used for any servers that may be included in the system. As with all of the SSL/TLS products the UCC provides secure transfer of information between a client and a server or, in some cases, a server and a server.

It uses the same definition of SSL as all other certificates. There is a public key and a certificate that is used to create the secure pathway between the client and the server or the server and server. The private key, only on the server, is then used to decrypt the information. This is identical to the other basic operations of any SSL/TLS product sold by Comodo or any other CA.

The difference with the UCC is in the ability of the certificate to work within the Microsoft Exchange and Office Communications servers environments. As it is able to incorporate the features and functions such as autodiscover, which takes a lot of the manual entry requirements within the systems.

This also makes it easier for users signing on with new devices to the network. As with all of the Comodo products the root certificate is embedded with the device and browser, so there are no UC browser with certificate issues.

The one possible complication may be with very old devices that are not able to read the SAN component of the certificate. To avoid this issue, we recommend choosing the primary common name on the UCC as the name used by those with older, mobile devices accessing the server. All other devices will be able to access the SAN feature of the certificate and this will avoid these issues.

The SAN feature of the UCC allows the IT administrator to add up to a total of 100 names to the certificate. This can include both domains and subdomains, making it a highly effective option to secure multiple sites without the need for separate IPs and individual certificates. It also eliminates the need to use the problematic Wildcards, a perfect way to cut down on user issues.
