Error: Invalid Login Credentials

[error] security : Authentication failure:Invalid login credentials

Solution: Verify the following:

• The user ID and password are valid and spelled correctly.
• Your authentication method is set up correctly. SAP Event Stream Processor supports a variety of authentication providers, all of which require configuration. To identify the configuration method or methods enabled on this node, open STREAMING_HOME/cluster/config/<cluster-name>/cluster.xml and look in the <Security> element. Compare the <Authenticator> elements here with the examples located at STREAMING_HOME/cluster/config/<cluster-name>/auth_*.xml.
• If you are using UNIX authentication, you have configured a pluggable authentication module.
• If you are using multiple cascading authentication methods, you have set controlFlag="sufficient" on each <authenticationProvider> or <config:authenticationProvider> element in the CSI file. This flag allows you to authenticate using only one authentication provider. Anyone who tries to log in using an authentication provider that lacks controlFlag="sufficient" must authenticate multiple times. ESP cycles through the authentication providers in the order in which they appear in the file; you cannot log in until you have authenticated against a provider whose definition includes controlFlag="sufficient".
