samba - Feb 2011 - Samba 3.5.6 - Windows 2008r2 domain trust fail

Hi,
 I'm trying to configure a Domain trust between Samba 3.5.6 (TEST domain)
and Windows 2008 r2 (WTEST Domain). Samba is the trusting side and Windows
is the trusted side. I created the "incoming trust" in the W2K8 called
TEST.
Then I executed the "net  rpc trustdom establish WTEST" and got:

Enter TEST$'s password:
Could not connect to server W2K8SERVER
Could not initialise lsa pipe. Error was NT_STATUS_ACCESS_DENIED

I tried with "net -d3 rpc trustdom establish WTEST" and got:

I haven't found information about trust between 2008 and Samba. May be
it's
not supported.
