All logon failures return a Logout message with an appropriate reason code and may include additional text which provides additional information regarding the failure. If the session initiator fails to authenticate with the system within a defined number of attempts, the account will be locked and all subsequent logon attempts will be rejected. If logons are disabled by the marketplace, a failure to logon will not cause the account to be locked but only rejected. Any other causes for authentication failure will cause the account to be locked after a defined number of failed attempts. To unlock the account requires marketplace operations to reset the account and assign a new password.
