[Samba] Samba 3 - Can't create trusted domain account

[Ganael LAPLANCHE]

Hi !

I'm using Samba 3 - simple smbpasswd backend, no winbind.
I try to use interdomain trusts between (samba) domains TRUSTED and
TRUSTING.

I get an error while creating the TRUSTED domain account :
smbpasswd -D 10 -a -i TRUSTED
>Get_Pwnam_internals didn't find user [TRUSTED$]!
>Failed initialise SAM_ACCOUNT for user TRUSTED$.
>Failed to modify password entry for user TRUSTED$
Samba can't find the entry, isn't it supposed to CREATE it ? How can I do
that ?
Did someone manage to do it ?

Thank you,
Ganaël.
