SASL PLAINTEXT

Olga Semme

SASL — authentication and data security framework used in Internet protocols.

PLAIN — simple mechanism for passing passwords in a clear text.

PLAINTEXT — authenticator that is configured to support the PLAIN authentication mechanism.

To enable authentication SASL PLAINTEXT with ADCM, do the following:

  1. On the cluster configuration tab in the configuration settings tree, enable the SASL_PLAINTEXT Authentication switch and expand the SASL_PLAINTEXT Auth username:password map node.

    Enable SASL_PLAINTEXT Authentication on the ADS cluster

  2. The nodes that open contain the default encrypted user passwords for each service designed to work with Kafka.

    Configuration nodes with users and passwords SASL_PLAINTEXT Authentication
    Configuration nodes with users and passwords SASL_PLAINTEXT Authentication

    When SASL_PLAINTEXT Authentication is enabled for the first time, passwords for users of each service are automatically generated:

    kafka: kafka-password
ksql-server: ksql-server-password
kafka-rest: kafka-rest-password
schema-registry: schema-registry-password
kafka-connect: kafka-connect-password

    It is recommended to change the default passwords.

  3. To change the password, click on <secret> next to the username, enter the new password, confirm the password and click Apply.

  4. Save the configuration by clicking Save.

  5. Restart all services for which authentication has been configured. To do this, apply the action Restart by clicking on the actions default dark actions default light in the Actions column.
