KB-40993: How does CentrifyDC agent determine the operatingSystemVersion attribute on a *nix computer object in AD?

Question: When looking at the Operating System tab of a *nix machine joined to AD using Centrify, there is a version number listed there. How does that value get determined?

For example, on a computer object in ADUC:

User-added image

Answer: Most Linux distributions list the OS version in the /etc/os-release file. Centrify will first use what is in this file. If this file does not exist, unreadable, etc., Centrify will then look for /etc/redhat-release, and other various OS identification files.
