commit 75eacdd7e0faa72775c4a143193edd594bd99ee7
Author: Jim McDonough <jmcd at samba.org>

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.
