If you are trying to use SPNEGO as the means for authenticating HCL Notes Connections Plug-In and you run into an issue, check if "Use the alias host name for the application server" option is used on Websphere Application Server and if that is the case try turning it off.

I came across an HCL Domino environment with HCL Sametime where the Sametime embedded clients were logging in via LTPA but with a different authentication server than the Sametime Community server. As you can imagine, this was important to keep in mind during a Sametime migration. The Domino server used for authenticating Sametime clients is also hosting multiple websites and using multiple LTPA tokens, so the question was, which LTPA token is actually used for authenticating the Sametime clients.

Recently I was installing an HCL Sametime 11 environment from scratch. I always tend to implement a single LTPA Token across the Domino, Sametime and/or Connections environment. It is also a very good idea to use only the LTPA Token version 2, as it is more secure, but this also means that the LTPA Token has to be created by a WebSphere server.

If you experience the issue with HCL Sametime 11 Proxy, where the WebClient just loads endlesly after a user logs in, and the following error is present in "catalina.out" log file (of the Sametime Proxy component): CLFRX0049E: Failed to query the user info: <username>, reason 80000005 Check the "UserInfoConfig.xml" file, on the Sametime Community Server,

In the HCL Sametime version 11 there is no System Console, which means that the Name Change tasks have to be created directly in the "stnamechange.nsf" database. This process is not documented. After trying to reinvent the wheel and failing gloriously, I decided to write a blog post about it. :-)

If you have implemented or planing to implement the "URL Preview" feature for HCL Connections, make sure you import the Root Certificate for "Let’s Encrypt" certificate authority inside the java trust store. By default, the root certificate of "Let’s Encrypt" certificate authority is not in the java trust store which the HCL
