Method Details
-
username
Specifies a static username that will be used for all authentication purposes.- Parameters:
username
- the username to use.- Returns:
- this builder for chaining purposes.
-
username
Specifies a dynamic username that will be used for all authentication purposes.Every time the SDK needs to authenticate against the server, it will re-evaluate the supplier. This means that you can pass in a supplier that dynamically loads a username from a (remote) source without taking the application down on a restart.
It is VERY IMPORTANT that this supplier must not block on IO. It is called in async contexts and blocking for a longer amount of time will stall SDK resources like async event loops.
- Parameters:
username
- the username to use.- Returns:
- this builder for chaining purposes.
-
password
Specifies a static password that will be used for all authentication purposes.- Parameters:
password
- the password to alongside for the username provided.- Returns:
- this builder for chaining purposes.
-
password
Specifies a dynamic password that will be used for all authentication purposes.Every time the SDK needs to authenticate against the server, it will re-evaluate the supplier. This means that you can pass in a supplier that dynamically loads a password from a (remote) source without taking the application down on a restart.

- Parameters:

- the password to alongside for the username provided.- Returns:

allowedSaslMechanisms
public PasswordAuthenticator.Builder allowedSaslMechanisms(Set<SaslMechanism> allowedSaslMechanisms) Allows to set a list of allowed SASL mechanisms for the NON-TLS connections.Note that if you add
SaslMechanism.PLAIN
to the list, this will cause credential leakage on the network since PLAIN sends the credentials in cleartext. It is disabled by default to prevent downgrade attacks. We recommend using a TLS connection instead.- Parameters:
allowedSaslMechanisms
- the list of allowed sasl mechs for non-tls connections.- Returns:
- this builder for chaining purposes.
-
enablePlainSaslMechanism
This method acts as a shortcut toallowedSaslMechanisms(Set)
which addsSaslMechanism.PLAIN
to the allowed mechanism list for NON TLS connections.Please note that this is INSECURE and will leak user credentials on the wire to eavesdroppers. This should only be enabled in trusted environments - we recommend connecting via TLS to the cluster instead.
If you are running an LDAP enabled environment, please use
onlyEnablePlainSaslMechanism()
instead!- Returns:
- this builder for chaining purposes.
-
onlyEnablePlainSaslMechanism
This method will ONLY enable the PLAIN SASL mechanism (useful for LDAP enabled environments).Please note that this is INSECURE and will leak user credentials on the wire to eavesdroppers. This should only be enabled in trusted environments - we recommend connecting via TLS to the cluster instead.
You might also want to consider using the static constructor method
PasswordAuthenticator.ldapCompatible(String, String)
as a shortcut.- Returns:
- this builder for chaining purposes.
