This global option tells Samba whether or not to allow access from users that have null passwords (encrypted or non-encrypted) set in their accounts. The default value is
no. You can override it as follows:
null passwords = yes
We highly recommend against doing so unless you are familiar with the security risks this option can present to your system, including inadvertent access to system users (such as
bin) in the system password file who have null passwords set.
