Realm names are used for network routing and authentication. They provide the identification required to forward authentication requests to the server that holds the user's credentials. In Windows, a realm name is often an Active Directory® Domain Services (AD DS) domain name. Realm information is used for dial-up connections only.

Realm name (include separator character)

Specifies the text added to the user name before it is sent to the remote server for authentication. Include the separator character that is to be used to separate the realm name from the user name.
