I think what Andrew is trying to say is that the gid may be incorrect.

The line that is causing the error is this:

smbd.set_simple_acl(file.name, 0o755, system_session_unix(), gid)

if you look at the code for that line, you will find this above it:

:param gid: The GID of the "Domain adminstrators" group

Which, now I think about it, is also a bug, there isn't a 'Domain 
administrators' group, but there is a domain 'Administrators' group.

so if you look in idmap.ldb , you should find this:

dn: CN=S-1-5-32-544
cn: S-1-5-32-544
objectClass: sidMap
objectSid: S-1-5-32-544
xidNumber: 3000002
distinguishedName: CN=S-1-5-32-544

S-1-5-32-544 is the SID the domain 'Administrators' group and, from the 
example above (taken from my DC), the 'gid' is '3000002'. Yours may be 
slightly different, but it should be in the '3000000' range.
