To the best of my knowledge, you are the 1st Kaseya customer asking about Novell in a context other than SLES/SLED and openSUSE. Since SLES is fully supported, I would expect OES to work correctly and accept support tickets if it did not.
As for our support group saying Novell isn't supported, its not listed as a supported OS and that list is what the support people would be basing what they told you on. Did you tell them Novell owns SuSE? If you had told them that then they should have passed the issue to a higher support tier.
