The client application begins the authentication process by emitting the <request-login> tag element within an <rpc> tag element. In the <request-login> tag element, it encloses the <username> tag element to specify the JUNOS account (username) under which to establish the connection. The account must already be configured on the JUNOScript server machine, as described in Prerequisites for All Access Protocols. You can choose whether or not the application provides the account password as part of the initial tag sequence.
