It looks like the AD information is only collected for Windows and Mac machines. I took a look at the property and the Relevance it uses. and then I looked up the “distinguished name of local computer of active directory” in the Inspector Search, and it shows this is only for Windows and Mac.
Has anyone else figured out how to use AD directory path for computers that are not mac or windows, such as Linux?
Is there another approach that can be taken?
Has a PMR been written for this enhancement?
That would be dependent upon your client-side implementation (OpenLDAP? Samba? Quest Authentication Service? Likewise? Centrify?)
That is part of the reason why its not yet done due to the complexity 
And you’d want an RFE filed not a PMR
So, on your client, how would you determine this info from the command line or config file entry?
Was looking to do this very thing with the product Centrify? Basically, windows we can use AD, but it would be great with Linux also. Is there a guide for creating groups using Centrify (as AD)?
I'm afraid not, I haven't looked at Centrify in quite a while.
The approach I think you'd likely need to take, is to use some Centrify command to output the text you want to a file, and then read the results in an Analysis.
If you know the commands to run and can give samples of the data we could help you with how to parse it.
Thanks. I’m still a little confused on “a file”. Is this a single file that has all the computers? Or a single file per computer?
I did read this post (seems Jason you were helping out then too! lol) Active Directory OU computer object automatic Groups - Usage and Config / Platform - BigFix Forum
Is there a ‘custom’ field I could use in bigfix to use as an identifier? IE:
101 linux prod servers to patch and reboot
102 linux prod servers to patch only
103 etc….
I’m open to ideas! 
How does Bigfix get the Active Directory Path? Is it from the agent installed doing a query? If I knew ‘how or where’ it stored it - I could have each linux machine put the information there for the agent?
