public class EPPLoginCmd extends EPPCommand
The EPP <login> command is used to establish a session with an EPP server in response to a greeting issued by the server. A <login> command MUST be sent to a server before any other EPP command to establish an ongoing session. A server operator MAY limit the number of failed login attempts N, 1 <= N <= infinity, after which a login failure results in the connection to the server (if a connection exists) being closed.
A client identifier and initial password MUST be created on the server before a client can successfully complete a <login> command. The client identifier and initial password MUST be delivered to the client using an out-of-band method that protects the identifier and password from inadvertent disclosure.
In addition to the standard EPP command elements, the <login> command contains the following child elements:

  • A <clID> element that contains the client identifier assigned to the client by the server.
  • A <pw> element that contains the client's plain text password. The value of this element is case sensitive.
  • An OPTIONAL <newPW> element that contains a new plain text password to be assigned to the client for use with subsequent <login> commands. The value of this element is case sensitive.

  • An <options> element that contains the following child elements:
  • A <version> element that contains the protocol version to be used for the command or ongoing server session.
  • A <lang> element that contains the text response language to be used for the command or ongoing server session commands.

The values of the <version> and <lang> elements MUST exactly match one of the values presented in the EPP greeting.
  • A <svcs> element that contains one or more <objURI> elements that contain namespace URIs representing the objects to be managed during the session. The <svcs> element MAY contain an OPTIONAL <svcExtension> element that contains one or more <extURI> elements that identify object extensions to be used during the session.

The PLAIN SASL mechanism presented in [RFC2595] describes a format for providing a user identifier, an authorization identifier, and a password as part of a single plain text string. The EPP authentication mechanism is similar, though EPP does not require a session-level authorization identifier and the user identifier and password are separated into distinct XML elements. Additional identification and authorization schemes MUST be provided at other protocol layers to provide more robust security services.
