Hi Crack, just what are you connecting with that needs lanman auth ? 

Rowland

Hi Rowland,
I am testing lanman auth option as I cannot login to Samba server with
correct samba user name & password
I created Unix user & samba user .. but cannot login to Samba ..
This is why I use this option to find a way to login to Samba

Best Regards,
Mr Linux CZ
