Chapter 5. Security realms

Security realms integrate Data Grid Server deployments with the network protocols and infrastructure in your environment that control access and verify user identities.

5.1. Creating security realms

Add security realms to Data Grid Server configuration to control access to deployments. You can add one or more security realm to your configuration.

Note

When you add security realms to your configuration, Data Grid Server automatically enables the matching authentication mechanisms for the Hot Rod and REST endpoints.

Prerequisites

  • Add socket bindings to your Data Grid Server configuration as required.

  • Create keystores, or have a PEM file, to configure the security realm with TLS/SSL encryption.

    Data Grid Server can also generate keystores at startup.

  • Provision the resources or services that the security realm configuration relies on.
    For example, if you add a token realm, you need to provision OAuth services.

This procedure demonstrates how to configure multiple property realms. Before you begin, you need to create properties files that add users and assign permissions with the Command Line Interface (CLI). Use the user create commands as follows: 

user create <username> -p <changeme> -g <role> \
     --users-file=application-users.properties \
     --groups-file=application-groups.properties

user create <username> -p <changeme> -g <role> \
     --users-file=management-users.properties \
     --groups-file=management-groups.properties
Tip

Run user create --help for examples and more information.

Note

Adding credentials to a properties realm with the CLI creates the user only on the server instance to which you are connected. You must manually synchronize credentials in a properties realm to each node in the cluster.

Procedure

  1. Open your Data Grid Server configuration for editing.
  2. Use the security-realms element in the security configuration to contain create multiple security realms.

  3. Add a security realm with the security-realm element and give it a unique name with the name attribute.

    Important

    Do not add special characters, such as hyphens (-) or ampersands (&), to security realm names. Data Grid Server endpoints can become unreachable if security realm names contain special characters.

    To follow the example, create one security realm named ApplicationRealm and another named ManagementRealm.

  4. Provide the TLS/SSL identify for Data Grid Server with the server-identities element and configure a keystore as required.

  5. Specify the type of security realm by adding one the following elements or fields:

    • properties-realm
    • ldap-realm
    • token-realm
    • truststore-realm

  6. Specify properties for the type of security realm you are configuring as appropriate.

    To follow the example, specify the *.properties files you created with the CLI using the path attribute on the user-properties and group-properties elements or fields.

  7. If you add multiple different types of security realm to your configuration, include the distributed-realm element or field so that Data Grid Server uses the realms in combination with each other.
  8. Configure Data Grid Server endpoints to use the security realm with the with the security-realm attribute.
  9. Save the changes to your configuration.

Multiple property realms

The following configuration shows how you can configure multiple security realms in XML, JSON, or YAML format:

XML

<server xmlns="urn:infinispan:server:13.0">
  <security>
    <security-realms>
      <security-realm name="ApplicationRealm">
        <properties-realm groups-attribute="Roles">
          <user-properties path="application-users.properties"/>
          <group-properties path="application-groups.properties"/>

        </properties-realm>
      </security-realm>
    </security-realms>
  </security>
</server>

        "name": "ManagementRealm",
        "properties-realm": {
          "groups-attribute": "Roles",
          "user-properties": {
            "digest-realm-name": "ManagementRealm",
            "path": "management-users.properties"
          },
          "group-properties": {

          "group-properties": {
            "path": "application-groups.properties"
          }
        }
      }]
    }
  }
}

YAML

      - name: "ManagementRealm"
        propertiesRealm:
          groupsAttribute: "Roles"
          userProperties:

          groupProperties:
            path: "application-groups.properties"

5.2. Setting up Kerberos identities

Add Kerberos identities to a security realm in your Data Grid Server configuration to use keytab files that contain service principal names and encrypted keys, derived from Kerberos passwords.

Prerequisites

  • Have Kerberos service account principals.
Note

keytab files can contain both user and service account principals. However, Data Grid Server uses service account principals only which means it can provide identity to clients and allow clients to authenticate with Kerberos servers.

In most cases, you create unique principals for the Hot Rod and REST endpoints. For example, if you have a "datagrid" server in the "INFINISPAN.ORG" domain you should create the following service principals:

  • hotrod/datagrid@INFINISPAN.ORG identifies the Hot Rod service.
  • HTTP/datagrid@INFINISPAN.ORG identifies the REST service.

Procedure

  1. Create keytab files for the Hot Rod and REST services.

    Linux
    ktutil
ktutil:  addent -password -p datagrid@INFINISPAN.ORG -k 1 -e aes256-cts
Password for datagrid@INFINISPAN.ORG: [enter your password]
ktutil:  wkt http.keytab
ktutil:  quit
    Microsoft Windows
    ktpass -princ HTTP/datagrid@INFINISPAN.ORG -pass * -mapuser INFINISPAN\USER_NAME
ktab -k http.keytab -a HTTP/datagrid@INFINISPAN.ORG
  2. Copy the keytab files to the server/conf directory of your Data Grid Server installation.
  3. Open your Data Grid Server configuration for editing.
  4. Add a server-identities definition to the Data Grid server security realm.
  5. Specify the location of keytab files that provide service principals to Hot Rod and REST connectors.
  6. Name the Kerberos service principals.
  7. Save the changes to your configuration.

5.3. Property realms

Property realms use property files to define users and groups.

  • users.properties contains Data Grid user credentials. Passwords can be pre-digested with the DIGEST-MD5 and DIGEST authentication mechanisms.
  • groups.properties associates users with roles and permissions.
Note

Properties files contain headers that associate them with security realms in Data Grid Server configuration.

users.properties

myuser=a_password
user2=another_password

groups.properties

myuser=supervisor,reader,writer
user2=supervisor

5.4. LDAP realms

LDAP realms connect to LDAP servers, such as OpenLDAP, Red Hat Directory Server, Apache Directory Server, or Microsoft Active Directory, to authenticate users and obtain membership information.

Note

LDAP servers can have different entry layouts, depending on the type of server and deployment. It is beyond the scope of this document to provide examples for all possible configurations.

Important

The principal for LDAP connections must have necessary privileges to perform LDAP queries and access specific attributes.

As an alternative to verifying user credentials with the direct-verification attribute, you can specify an LDAP attribute that validates passwords with the user-password-mapper element.

Note

You cannot use endpoint authentication mechanisms that perform hashing with the direct-verification attribute.

Because Active Directory does not expose the password attribute you can use the direct-verification attribute only and not the user-password-mapper element. As a result you must use the BASIC authentication mechanism with the REST endpoint and PLAIN with the Hot Rod endpoint to integrate with Active Directory Server. A more secure alternative is to use Kerberos, which allows the SPNEGO, GSSAPI, and GS2-KRB5 authentication mechanisms.

The rdn-identifier attribute specifies an LDAP attribute that finds the user entry based on a provided identifier, which is typically a username; for example, the uid or sAMAccountName attribute. Add search-recursive="true" to the configuration to search the directory recursively. By default, the search for the user entry uses the (rdn_identifier={0}) filter. Specify a different filter with the filter-name attribute.

The attribute-mapping element retrieves all the groups of which the user is a member. There are typically two ways in which membership information is stored:

  • Under group entries that usually have class groupOfNames in the member attribute. In this case, you can use an attribute filter as in the preceding example configuration. This filter searches for entries that match the supplied filter, which locates groups with a member attribute equal to the user’s DN. The filter then extracts the group entry’s CN as specified by from, and adds it to the user’s Roles.

  • In the user entry in the memberOf attribute. In this case you should use an attribute reference such as the following:

    <attribute-reference reference="memberOf" from="cn" to="Roles" />

    This reference gets all memberOf attributes from the user’s entry, extracts the CN as specified by from, and adds them to the user’s Roles.

5.4.1. LDAP realm principal re-writing

SASL authentication mechanisms such as GSSAPI, GS2-KRB5 and Negotiate include a username that needs to be cleaned up before you can use it to search LDAP directories.

5.5. Token realms

Token realms use external services to validate tokens and require providers that are compatible with RFC-7662 (OAuth2 Token Introspection), such as Red Hat SSO.

5.6. Trust store realms

Trust store realms use certificates, or certificates chains, that verify Data Grid Server and client identities when they negotiate connections.

Keystores
Contain server certificates that provide a Data Grid Server identity to clients. If you configure a keystore with server certificates, Data Grid Server encrypts traffic using industry standard SSL/TLS protocols.
Trust stores
Contain client certificates, or certificate chains, that clients present to Data Grid Server. Client trust stores are optional and allow Data Grid Server to perform client certificate authentication.

Client certificate authentication

You must add the require-ssl-client-auth="true" attribute to the endpoint configuration if you want Data Grid Server to validate or authenticate client certificates.

5.7. Distributed security realms

Distributed realms combine multiple different types of security realms. When users attempt to access the Hot Rod or REST endpoints, Data Grid Server uses each security realm in turn until it finds one that can perform the authentication.
