Estou tentando acessar o recurso SMB/CIFS no NetApp, usando o seguinte e obtendo o erro:

$ cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core) 
$ rpm -qa | grep ^samba-
samba-client-4.2.10-6.el7_2.x86_64
samba-libs-4.2.10-6.el7_2.x86_64
samba-common-libs-4.2.10-6.el7_2.x86_64
samba-common-4.2.10-6.el7_2.noarch
samba-client-libs-4.2.10-6.el7_2.x86_64
samba-common-tools-4.2.10-6.el7_2.x86_64
$ smbclient //X/Y$ -U DOMAIN/user -L
Enter DOMAIN/user's password: 
ntlmssp_handle_neg_flags: Got challenge flags[0x60898205] - possible downgrade detected! missing_flags[0x00000010] - NT code 0x80090302
  NTLMSSP_NEGOTIATE_SIGN
SPNEGO(ntlmssp) login failed: NT code 0x80090302
session setup failed: NT code 0x80090302
$

Estou tentando usar o seguinte com o meu smbclient:

--opção==

Set the smb.conf(5) option "<name>" to value "<value>" from the command line. This overrides compiled-in defaults and options read from the configuration file.

no entanto, ainda não consigo acessar o recurso no servidor porque estou fazendo errado:

$ smbclient //X/Y$ -U DOMAIN/user -L --option='client ntlmv2 auth'=no
Enter DOMAIN/user's password: 
Connection to --option=client ntlmv2 auth=no failed (Error NT_STATUS_UNSUCCESSFUL)
$

Qual é a maneira certa de definir client ntlmv2 auth=novia --optionin smbclient?

    Você pode desabilitar o spnego no ntlmssp, com os parâmetros padrão:

    # smbclient -L //MY_SERVER -U MY_USER Enter MY_USER's password: ntlmssp_handle_neg_flags: Got challenge flags[0x60898205] - possible downgrade detected! missing_flags[0x00000010] - NT code 0x80090302 NTLMSSP_NEGOTIATE_SIGN

    com spnego desativado:

    # smbclient -L //MY_SERVER -U MY_USER --option='client use spnego=no'

    funcionou para mim.
