Authentication

The SOCKS daemon can be configured to require authentication to use its services. Authentication is based on the host name and port of the connecting client. If you choose to require a user name and password, the information is authenticated against a user name and password file referenced by the socks5.conf file. If the provided user name and password do not match a listing in the password file, access is denied. The format for user names and passwords in the password file is username password, where the user name and password are separated by a space. .

You can also ban users. To require user name and password authentication, the SOCKS5_PWDFILE directive must be added to socks5.conf. For more information about the directive and its syntax, see the socks5.conf section in the Proxy Server Configuration File Reference

User name and password authentication can also be performed against a configured LDAP server, and not just a file.
