commit 880d1a3f83a0834225d5a7c0f179c236b0e59ef8
Author: Jim McDonough <jmcd at samba.org>
Date:   Mon Jun 29 10:06:14 2009 -0400

    Don't require "Modify property" perms to unjoin (bug #6481) "net ads leave" stopped working when "modify properties" permissions were not granted (meaning you had to be allowed to disable the account that you were about to delete).
    
    Libnetapi should not delete machine accounts, as this does not
    happen on win32.  The WKSSVC_JOIN_FLAGS_ACCOUNT_DELETE flag
    really means "disable" (both in practice and docs).
    
    However, to keep the functionality in "net ads leave", we
    will still try to do the delete.  If this fails, we try
    to do the disable.
    
    Additionally, it is possible in windows to not disable or
    delete the account, but just tell the local machine that it
    is no longer in the account.  libnet can now do this as well.
    
    Don't use ads realm name for non-ads case.  #6481
    
    Also check that the connection to ads worked.
