Thank you Gordon for this tip but it does not solve my problem. From smb.conf: workgroup = NT4DOMAIN netbios name = NT4MEMBER I am able to connect to smb share from linux client: smbclient //NT4MEMBER/share1 -U NT4MEMBER\\user1 but from windows machine it is not possible. Correct command from linux client should be smbclient //NT4MEMBER/share1 -U NT4DOMAIN\\user1 (user is from NT4DOMAIN, not from NT4MEMBER) This command is not working after upgrade. Logs say something about crap domain: [26721]: pam auth crap domain: [NT4DOMAIN] user: user1 [26699]: pam auth crap domain: NT4DOMAIN user: user1 set_dc_type_and_flags_connect: DC for domain NT4DOMAIN claimed it was a DC for domain NT4MEMBER, refusing to initialize NTLM CRAP authentication for user [NT4DOMAIN]\[user1] returned NT_STATUS_NO_MEMORY From Windows clients there is no way how to connect. It looks like winbindd should use NT4DOMAIN but using NT4MEMBER.
