Hi,d When trying ntlm auth = no on one of my samba servers it broke all my monitoring because smbclient failed to negotiate. After troubleshooting I found that it was not trying ntlmv2 as it should so I set client ntlmv2 auth = yes and then retried. It worked. However, other samba servers failed to connect (notably those using share level security) as it wanted lanman auth. So I set client lanman auth = yes as well but this didn't seem to help, the ntlm client setting was probably overriding it. So now it seems I have hit a circular dependency in the I cannot use ntlmv2 anywhere without the smbclient access breaking, and if I set smbclient to allow ntlmv2 to work, it breaks backwards compatibility. I cannot upgrade one of the servers out of share level security at the moment (it broke when I tried making it user level security). I don't understand why allowing ntlmv2 in the client must be mutually exclusive to using down level protocols. I understand that in most cases you want a way of preventing downgrading, but in my specific case I cannot do that just yet. Is there a way of allowing smbclient to connect to ntlmv2 or downward protocols optionally as this makes sense in this specific case? I understand that what I'm asking for may be considered non-ideal but I'd still like to know... -h -- Hari Sekhon
