Hello, 

despite my previous answer (https://pitstop.manageengine.com/portal/en/community/topic/sdp-doesnt-fill-domain-name-in-users-details-during-ldap-import) marked as "Answered", I stil can't resolve this issue.

As Dinesh said, I can configure default attributes, which (as said in refered documentation) include domain name, on the Admins -> Users -> LDAP page, but there is literally NOTHING about domain name.

So, I tried to use sdldapfieldmap, but stumbled that I do not know what to write in sdfieldname. Is there a document describing visible user attributes and their internal name? The one I need I attached in a screenshot.
