[Samba] wbinfo -u fails (but not wbinfo -t and wbinfo -g)

[Mauro (INTERFREE)]

Hi all,
I'm tring to configure samba 3.0.10 on hpux machine as domain member.
Unluckly I got some error.
When I try to open my server froma a windos machine it seems all ok:

[2005/07/25 15:42:19, 0] smbd/server.c:open_sockets_smbd(383)

  check_ntlm_password:  authentication for user [mgatt] -> [mgatt] -> [mgatt] succeeded

but when i open a share, even if I  reach to do it, i got some errors. It seems  samba looses user and domain info.

wbinfo -t and wbinfo -g work fine but wbinfo -u gives me error:
Error looking up domain users

Please could you help me to find correct way to solve my problems?

Thank You
