#* The server renders this HTML page whenever the Domain Authentication Selector is invoked. In such a event, the authentication selector logic will be invoked to evaluate which authentication source. This HTML page will prompt the user to input an email address or complete domain name. From the provided domain name or email address, PingFederate can determine what authentication source to send their request to. Velocity variables (identified by the $ character) are generated at runtime by the server. *# #set( $messageKeyPrefix = "sample.authn.selector.email.template." )
