Ok,

try out with objectclass sambaGroupMapping.
Get
adding new entry "uid=test,ou=people,dc=xxx,dc=xx"
ldapadd: Object class violation (65)
additional info: object class 'sambaGroupMapping' requires attribute 'sambaSID'

and that´s what I searching for!

try out with objectclass sambaAccount
Get
adding new entry "uid=test,ou=people,dc=xxx,dc=xx"
ldapadd: Invalid syntax (21)
additional info: objectClass: value #2 invalid per syntax

value #2 is the objectclass sambaAccount

This should normally work.
Do not know why getting a Invalid syntax error.
Objectclass sambaAccount have only uid and rid as MUST attribute and is AUXILARY.
I have post it to openldap-technical list.
Hope they know what´s going wrong.

Also try out remote console access and api configuration.
But both terminals have a limited command set.
Nothing like net getlocalsid / getdomainsid.
Access from outside with the commands also want work.

Can't fetch domain SID for name: xxx.xxx.xx.xx


Any other suggestions?
Thanks
