Indicate whether an authentication attempt succeeded. The Junos XML protocol server returns the tag element in response to the <request-login> tag element emitted by a client application that uses the clear-text or Secure Sockets Layer (SSL) access protocol.



Specifies the username that the client application provided to an authentication utility such as RADIUS or TACACS+. This tag element appears only if the username that it contains differs from the username contained in the <message> tag element.


Names the account under which a connection to the Junos XML protocol server is established, if authentication succeeds. If authentication fails, explains the reason for the failure.


Indicates whether the authentication attempt succeeded. There are two possible values:

  • fail—The attempt failed. The Junos XML protocol server also emits the <challenge> tag element to request the password again, up to a maximum of three attempts.

  • success—The attempt succeeded. An authenticated connection to the Junos XML protocol server is established.
