This option specifies the maximum number of client connections that a share can have at any given time. Any connections that are attempted after the maximum is reached will be rejected. The default value is
0, which means that an unlimited number of connections are allowed. You can override it per share as follows:
[accounting]
max connections = 30
This option is useful in the event that you need to limit the number of users who are accessing a licensed program or piece of data concurrently.
