Configuring Pulse Authentication

Pulse requires all users to authenticate themselves before they can use the Pulse Web application.

If you run Pulse in embedded mode, the Pulse application runs on the JMX Manager node and no JMX authentication is required. You do not need to specify valid JMX credentials to start an embedded Pulse application.

If you host Pulse on a web application server (non-embedded mode) and you configure JMX authentication on the Tanzu GemFire manager node, then the Pulse Web application must authenticate itself with the manager node when it starts. Specify the credentials of a valid JMX user account in the pulse.properties file, as described in Hosting Pulse on a Web Application Server.

Note: The credentials that you specify must have both read and write privileges in the JMX Manager node. See Configuring a JMX Manager.

Configuring Pulse to use HTTPS

You can configure Pulse to use HTTPS in either embedded or non-embedded mode.

Embedded Mode

In embedded mode, Tanzu GemFire uses an embedded Jetty server to host the Pulse Web application. To make the embedded server use HTTPS, you must enable the http SSL component in gemfire.properties or gfsecurity.properties. See SSL for details on configuring these parameters.

These SSL parameters apply to all HTTP services hosted on the JMX Manager, which includes the following:

Developer REST API service
Management REST API service (for remote cluster management)
Pulse monitoring tool

When the http SSL component is enabled, all HTTP services become SSL-enabled and you must configure your client applications accordingly. For SSL-enabled Pulse, you will need to configure your browsers with proper certificates.

Non-Embedded (Standalone Web Server) Mode

In non-embedded mode where you are running Pulse on a standalone web application server, such as Tomcat, you must use the web server’s SSL configuration to make the HTTP requests secure. You must also set the Spring profile.

To set the Spring profile, set the spring.profiles.active system property.

On a command line, run:

export CATALINA_OPTS=-Dspring.profiles.active=pulse.authentication.gemfire

./catalina start

Configuring Pulse to use Security Manager

You can configure Pulse to use the Tanzu GemFire Security Manager in either embedded or non-embedded mode.

Embedded Mode

To use Security Manager with Pulse running in embedded mode, you do not need to specify additional credentials. Pulse will automatically be configured by Tanzu GemFire to send the credentials entered in the Pulse login page to the Security Manager for authentication and authorization.

Non-Embedded (Standalone Web Server) Mode

When running Pulse on a standalone web application server, such as Tomcat, you need to configure the Pulse Web app to use a Tanzu GemFire-specific security profile. Activate the Tanzu GemFire profile at startup with the system property:

-Dspring.profiles.active=pulse.authentication.gemfire

Configuring Pulse to use a Custom Security Profile

You can use a custom security profile only if you are NOT using a Security Manager in your cluster. A custom security profile only controls who can access the Pulse Web page. You will need to create an XML file named pulse-authentication-custom.xml that defines the credentials and roles of the users of Pulse.

Example pulse-authentication-custom.xml for Spring simple in-memory User Details Service

<beans:beans >
  <authentication-manager>
    <authentication-provider>
      <user-service id="userDetailsService">
        <user name="john" password="johnspassword" authorities="ROLE_CLUSTER:READ" />
        <user name="bob" password="bobspassword" authorities="ROLE_CLUSTER:READ" />
      </user-service>
    </authentication-provider>
  </authentication-manager>
</beans:beans>

Embedded Mode

Put pulse-authentication-custom.xml in the locator’s working directory. When you start Tanzu GemFire members, specify the custom authentication profile using the -Dspring.profiles.active=pulse.authentication.custom system property. For example:

gfsh> start locator --name=locator --J=-Dspring.profiles.active=pulse.authentication.custom

Start Pulse and log in using credentials that are authorized in the custom configuration.

Non-Embedded (Standalone Web Server) Mode

Put pulse-authentication-custom.xml in the Pulse Web app’s classpath, and start the app with the system property:

-Dspring.profiles.active=pulse.authentication.custom

Start Pulse and log in using credentials that are authorized in the custom configuration.

Configuring Pulse to use an OAuth Authentication Provider

You can configure Pulse to use any Authentication Provider that supports OpenID and custom scopes. You will need to:

Register with the authentication provider, obtaining a valid client ID and client secret for Pulse.
Configure the scopes with CLUSTER:READ, CLUSTER:WRITE, DATA:READ or DATA:WRITE.

Pulse Properties for OAuth Configuration

After you set up the authentication provider properly, create a properties file named pulse.properties (or edit it, if it already exists) to define the following required properties:

pulse.oauth.providerId

An ID for Pulse to use internally to identify your OAuth provider.
pulse.oauth.providerName

A name for Pulse to display on the login page to link to your OAuth provider.
pulse.oauth.clientId

The ID with which Pulse is registered with your OAuth provider.
pulse.oauth.clientSecret

The secret with which Pulse is registered with your OAuth provider.
pulse.oauth.authorizationUri

The URI for your OAuth provider’s authorization endpoint.
pulse.oauth.tokenUri

The URI for your OAuth provider’s token endpoint.
pulse.oauth.userInfoUri

The URI for your OAuth provider’s user info endpoint.
pulse.oauth.jwkSetUri

The URI for your OAuth provider’s JSON Web Key (JWK) Set endpoint.
pulse.oauth.endSessionEndpoint

The URI for your OAuth provider’s endpoint to request that the end user be logged out. See the end_session_endpoint parameter of the OpenID Provider Discovery Metadata standard proposal.
pulse.oauth.userNameAttributeName

The attribute name used to access the user’s name from your OAuth provider’s user info response.

Example pulse.properties for OAuth Configuration

pulse.oauth.providerId=uaa
pulse.oauth.providerName=UAA
pulse.oauth.clientId=pulse
pulse.oauth.clientSecret=example-pulse-client-secret
pulse.oauth.authorizationUri=http://example.com/uaa/oauth/authorize
pulse.oauth.tokenUri=http://example.com/uaa/oauth/token
pulse.oauth.userInfoUri=http://example.com/uaa/userinfo
pulse.oauth.jwkSetUri=http://example.com/uaa/token_keys
pulse.oauth.endSessionEndpoint=http://example.com/uaa/profile
pulse.oauth.userNameAttributeName=user_name

Embedded Mode

Create the above pulse.properties file and put it in the member’s working directory.
Start up the member with a Tanzu GemFire property (either specify it in gemfire.properties file or pass it in at startup) security-auth-token-enabled-components=pulse or security-auth-token-enabled-components=all.
```
gfsh> start locator --name=locator --J=-Dgemfire.security-auth-token-enabled-components=pulse
```

Start pulse and you will see login page being redirected to the configured authentication provider.

Non-Embedded (Standalone Web Server) Mode

Edit the existing pulse.properties file and add the above content, make sure the file is in the web app’s classpath

Start the app with the system property:

-Dspring.profiles.active=pulse.authentication.oauth

Start Pulse and you will see login page being redirected to the configured authentication provider.
