[User Aliases]

This section will replace a user name specified in the connect string of a DNS with an internal alias. This alias is used in the third colon delimited field of a mapping rule.

The example below shows how certain users or an empty user are handled. In this case they are rejected.

[User Aliases]
scott|system = insecure
^$           = blank

[Mapping Rules]
*:*:blank:*:*:*:rw     = reject You should specify a username
*:*:insecure:*:*:*:rw  = reject The user is not allowed
