Subject: a netlogon enum trust query doesn't have a function_code at end.
X-Git-Tag: samba-4.0.0alpha6~801^2~19196
X-Git-Url: http://git.samba.org/samba.git/?a=commitdiff_plain;h=11d999f2bc0c841696bc3ea1ddda48524242482c;p=ira%2Fwip.git

a netlogon enum trust query doesn't have a function_code at end.
a sam_user_info_24 doesn't have a uint16 at end
samr_create_user also creates the unix account now
samr_set_userinfo changes the password.

        J.F.
