Computer Objects in Active Directory have the "RHEL Version String" Instead of "Linux" as the "operatingSystem" attribute. -
Descrizione
Some computer objects in Active Directory (AD) have the Red Hat Enterprise Linux (RHEL) version string instead of "Linux" as the "operatingSystem" attribute. -
Causa
This is by design.
When joining a server to the domain Authentication Services (AS) uses “uname –s” to determine the operating system and populates the "operatingSystem" attribute in AD with the output.
However if "redhat-lsb" packages are installed on the server then AS runs “lsb_release –s –d” and it’s this command that is determining the content of the “operatingSystem” attribute.
Every 24 hours AS will update this attribute so if it has been manually updated in AD it will revert to the original setting daily. The same applies if vasd is restarted or the server is rebooted. Please note that these permissions are not set by default during installation, they must be manually set. -
Risoluzione
If there is a requirement to display the output from "uname -s" instead of “lsb_release –s –d” then the "operatingSystem" attribute in AD would need to be updated manually and the permissions which allow the daily update would have to be unset.
The specific permission’s which are set in AD to allow this update to happen and are detailed in the following KB article.

The value of the "operatingSystem" attribute can be either changed directly in AD by editing the attribute for the computer object concerned.
or
It can be edited from the Linux server by running the following command.
/opt/quest/bin/vastool -u setattrs -s host/ operatingSystem "Linux"
