3101ac93e2 netlogon_creds_cli: Avoid a static const struct
Same number of .text bytes, but simpler code.

Yes, this is {{0}} instead of {0}, which I always promote. I've just read a
comment on stackoverflow (which I've unfortunately just closed the tab for :-()
that {{0}} might actually be the correct way to init a struct to zero if the
first struct element is again a struct. I'm lost. 25 years of C coding and I
have no clue of the language :-(

This error code is currently documented by Microsoft under System Error

d139d77ae3 auth: Allow NTLMv1 if MSV1_0_ALLOW_MSVCHAPV2 is given and re-factor 'ntlm auth ='
The ntlm auth parameter is expanded to more clearly describe the
role of each option, and to allow the new mode that permits MSCHAPv2
(as declared by the client over the NETLOGON protocol) while
still banning NTLMv1.

BUG: https://bugzilla.samba.org/show_bug.cgi?id=12252
Signed-off-by: Andrew Bartlett <abartlet@samba.org>

Based on a patch by Mantas Mikulėnas <mantas@utenos-kolegija.lt>:

Commit 0b500d413c ("Added MSV1_0_ALLOW_MSVCHAPV2 flag to ntlm_auth")
added the --allow-mschapv2 option, but didn't implement checking for it
server-side. This implements such checking.

Additionally, Samba now disables NTLMv1 authentication by default for
security reasons. To avoid having to re-enable it globally, 'ntlm auth'
becomes an enum and a new setting is added to allow only MSCHAPv2.
