I have been googling all over the place and can't find an answer to this problem.


I am testing Mac 10.8 with our product.  I have tested NTLMv2 and Kerberos both work. But I can't get NTLMv1 to work.


Does Mac 10.8 still support NTLMv1?  If so, how do I configure it?


It used to be I did "sudo vi /private/etc/nsmb.conf", made "minauth=ntlmv2_off",

this enabled ntlmv1. But the nsmb.conf file nolonger exists. Any ideas?


If it turns out that Mac not longer supports NTLMv1, that's ok. I just need to know.


Thank you,


Mac mini, OS X Mountain Lion (10.8.1)

    So not having a clue what NTLMv1 is or was, was it a Power PC Application?

    I am fairly certain Lion and Mountain Lion no longer support NTLMv1 authentication. When Lion was introduced Apple replaced the previously used Samba software with their own SMBX software which uses the SMB2 protocol. The main reason for replacing Samba was due to the Samba project moving to a GIT3 licensing scheme which Apple was unable to use.


    Apple's SMBX appears to use a plist configuration file for its settings which is located at /Library/Preferences/SystemConfiguration/


    Note: It is in theory possible to leave Apple's own SMBX turned off and then to personally install a version of Samba. You would then be able to use the same preferences as Snow Leopard and other Samba implementations and would be compatible with NTLMv1. A Mac friendly build of Samba for use on Lion/Mountain Lion is availble here

    10.7 Lion and 10.8 Mountain Lion both use the new SMBX and hence would have the same results.
