ntlm_auth can also do negotiate (which is much more efficient if
Kerberos is selected, I agree), however it looks like --require-
membership-of isn't hooked up to that (drat).
The easiest way past the escaping issue is to pass the SID as S-x-y-z.
The reason --require-membership-of was implemented is that it can be
much more efficient, as at this point Samba knows the group memberships
so can look them up from the authentication reply, rather than starting
new LDAP traffic.
