Hazelcast IMDG Standard Support has expired. Extended support for version 4.1 ends in April 2024. Extended support for version 4.2 ends in September 2024.

We recommend that you try Hazelcast Platform.

In Hazelcast Platform, we’ve combined the in-memory storage of IMDG with the stream processing power of Jet. Find out more in our Platform documentation.

The following topics are a good place to start:

Default authentication

The Default Authentication is used when security is enabled and no explicit authentication configuration is provided. It can happen when:

  • member-authentication is not configured

  • the security realm referenced by member-authentication doesn’t contain the authentication configuration

  • client-authentication is not configured

  • the security realm referenced by client-authentication doesn’t contain the authentication configuration.

The behavior of the default authentication mechanism depends on member’s identity configuration (i.e., identity configuration in the security realm referenced from member-authentication). If the identity is configured as a username-password, then the authenticated username and password credentials are checked for equality with these configured ones. In all other cases, only the incoming cluster name is checked for equality with the one configured on the authenticating member.
