Hi all, I have gotten this working; However, I am just curious about a few things and wanted to see if anyone on this list might know. My setup is Fedora/Linux based - but I believe these comments to be valid for any OS. When joining the computer to the domain using net join I am unable to do a: # net ads join -U Administrator Gives me ads_join_realm: Insufficient access so we try net rpc join -U Administrator Which works fine - Any thoughts why??? Question #2 Joining a computer to an AD domain like this works - but we see a great deal of pre-authentication errors in our Domain logs - I have seen the MS KB articles that talk about not requiring preauth to get rid of this message - but the problem is that the option to Not require pre-auth is valid for a user object not a computer object -so setting this option still does not get rid of the errors claiming the machine object is failing pre-auth.
