[Samba] I can't see users on a AD domain, how to fix it?

[Mr Vampire]

/usr/local/samba/bin/wbinfo --sequence

AD1 : DISCONNECTED
AD2 : 10074

 /usr/local/samba/bin/smbpasswd -j AD2 -r PDS -U Administrator%password

Joined domain AD2

AD2 and AD1 are both child of an AD. I also have manually trusted AD1 with
AD2 but doesn't seem to work

any suggest?

thank you!
