Subject: Changes to help the kerberos change password code work on systems that
X-Git-Tag: samba-4.0.0alpha6~801^2~11793^2~1717

Changes to help the kerberos change password code work on systems that
have some of the labels 'duplicated' (ie, the defines double-up).

Also, to an ads_connect() to try and find our KDC. (So we don't segfualt
*every* time)
