interdomain trust problem

[Lin Li]

I have a samba (3.0.20b) domain and NT4 domain trusted each other. My 
samba (3.0.20b) client machine joined the samba domain. When I try to 
authenticate an nt domain user on the client machine, I got error 
NO_SUCH_USER. The log on the samba pdc shows:

It seems in the make_server_info_info3 call , samba tries to look for 
the user on the samba pdc. If I add a user with the same name but 
different password on the samba pdc, the authentication suceded. I see 
similar question asked in the samba mail list. Any help?

Thanks,
Lin
