CVE-2020-25717: s3:auth: remove fallbacks in smb_getpwnam()
So far we tried getpwnam("DOMAIN\account") first and
always did a fallback to getpwnam("account") completely
ignoring the domain part, this just causes problems
as we mix "DOMAIN1\account", "DOMAIN2\account",
and "account"!
As we require a running winbindd for domain member setups
we should no longer do a fallback to just "account" for
users served by winbindd!
For users of the local SAM don't use this code path,
as check_sam_security() doesn't call check_account().
The only case where smb_getpwnam("account") happens is
when map_username() via ("username map [script]") mapped
"DOMAIN\account" to something without '\', but that is
explicitly desired by the admin.
Note: use 'git show -w'
