Thanks Richard for the reply.

Yes you are correct, joining domain its self will create the builtin
Administrators and Users only on the below idmap settings i.e with DOMAIN
specified.

 idmap config * : backend = tdb
 idmap config * : range = 2000000-2999999
 idmap  config CORP : backend = hash
 idmap config CORP :  range = 10000000-109999999

# id administrator

uid=10000500(administrator) gid=10000513(domain users)
groups=10000513(domain users),10005439(netmon users),10000572(denied rodc
password replication group),10000519(enterprise admins),10000518(schema
admins),10000512(domain admins),10000520(group policy creator
owners),10001149(adtest-group-1),
*2000001(BUILTIN\users),2000000(BUILTIN\administrators)*

But when I give as below I don't see the it get create by default.


 idmap config * : backend = tdb
 idmap config * : range = 2000000-2999999
 idmap config * : backend = hash
 idmap config * :  range = 10000000-109999999

# id administrator

uid=10000500(administrator) gid=10000513(domain users)
groups=10000513(domain users),10005439(netmon users),10000572(denied rodc
password replication group),10000519(enterprise admins),10000518(schema
admins),10000512(domain admins),10000520(group policy creator
owners),10001149(adtest-group-1)

# net sam list builtin  ====> Empty
