[SSSD] SSSD (another) wish-list

Hi list, Currently, we are using Centrify for Linux&AD integration so I was thinking we could soon save some $$$ and use sssd for the same purpose. There is still one thing (among others to which a RFEs have already been submitted) I am missing: Would it be possible for sssd to maintain the OperatingSystem attribute in AD updated? I know that IPA uses quite minimalistic LDAP schema so it is pity that it does not have any such an attribute, but if it had (comments needed), the same code could be used for IPA and AD domains. I am asking for auditing purposes - currently with Centrify it is easy to query AD just for OperatingSystem attribute and one can immediately see which OSes have been installed in the company. Many thanks, Ondrej
