[Samba] Is this group mapping good?

[Joel Rosental R.]

Hello, i have a doubt, i'm trying to setup a Samba server using a ldap
passdb backend using debian sarge.

when i configure /etc/smbldap-tools/smbldap.conf
and /etc/smbldap-tools/smbldap-bind.conf right, and do:

smbldap-populate

ok, it creates default windows group, but when i do a 'net groupmap
list' it shows me something like this:

Domain Admins (S-1-5-21-1085031214-299502267-1801674531-512) -> 512
Domain Users (S-1-5-21-1085031214-299502267-1801674531-513) -> 513
Domain Guests (S-1-5-21-1085031214-299502267-1801674531-514) -> 514
Domain Computers (S-1-5-21-1085031214-299502267-1801674531-515) -> 515
Administrators (S-1-5-32-544) -> 544
Print Operators (S-1-5-32-550) -> 550
Backup Operators (S-1-5-32-551) -> 551
Replicators (S-1-5-32-552) -> 552

So i don't know if it's good.. i don't understand why it doesn't put
names, but anyway, will this mapping cause me problems when migrating?

Thanks and hoping an answer.. :)
