Hi Guys 

JUsta  newbie question. I've been reading Cap 11 from Samba-HOWTO, and
when I follow the example:
group domadm=root,Administrador and make

net groupmapp add ntgroup="Domain Admins" uxingroup=domadm itś ok, but I
received the following answer:

hercules:~# net groupmap list
System Operators (S-1-5-32-549) -> -1
Domain Users (S-1-5-21-3939155289-3141390475-2008170846-513) -> -1
Replicators (S-1-5-32-552) -> -1
Guests (S-1-5-32-546) -> -1
Domain Admins (S-1-5-21-3939155289-3141390475-2008170846-1001) ->
Administrador
Power Users (S-1-5-32-547) -> -1

                                                         ^^^^^^^^^^^^^^^
Backup Operators (S-1-5-32-551) -> -1
Users (S-1-5-32-545) -> -1

Question: How can I make this?? ( as the Howto says..80))
Domain Admins (S-1-5-21-3939155289-3141390475-2008170846-512) -> domadm
????                                                     ^^^^^^^^^^^^^


Thanks in advanced
