How to configure server password?

Hi, I set up a dedicated server with password, but the clients do not need to specify the password to join. Am I doing it wrong?

```
sv_port 8303
sv_rcon_password rconPassword
sv_name "Ninslash Server (0.4.10)"
password serverPassword
sv_motd ""
```

The clients show the server with "Password: Yes" but they can join without pw.

Thx!
