Sametime 12.0.3 chat server is available on Windows. You may want to have SSO, for example with Domino to have awareness status in email.
You then need a LTPA key, which is very easy to create if you use Docker as referenced in the documentation here https://help.hcl-software.com/sametime/v1203/admin/ltpa_generate_key.html
But what if you don’t use Docker? You need a way to generate a LTPA key in Windows. I found out that is not hard as it may seem and in this post I will explain how to do this.
