OK, I setup outgoing trust from AD to Samba domain but it stops at 
Validation. When I click on Validate, I get the following error:

Verification of the trust between the domain AD_DOMAIN and the domain 
SAMBA_DOMAIN was unsuccessful because: Access is denied.
To repair a trust to a pre-Windows 2000 domain you must remove and 
re-add the trust on both sides.

On Samba side I have user "domaintrust" with samba flag [I] (added and 
edited trough Ldapadmin tool in ou=People,dc=domain,dc=tld) and the same 
user and password in AD.
What can I do to get this to work?
