Available on crate feature postgres only.

Variants

Ok

The authentication exchange is successfully completed.

CleartextPassword

The frontend must now send a [PasswordMessage] containing the password in clear-text form.

Md5Password(AuthenticationMd5Password)

The frontend must now send a [PasswordMessage] containing the password (with user name) encrypted via MD5, then encrypted again using the 4-byte random salt.

Sasl(AuthenticationSasl)

The frontend must now initiate a SASL negotiation, using one of the SASL mechanisms listed in the message.

The frontend will send a [SaslInitialResponse] with the name of the selected mechanism, and the first part of the SASL data stream in response to this.

If further messages are needed, the server will respond with Authentication::SaslContinue.

SaslContinue(AuthenticationSaslContinue)

This message contains challenge data from the previous step of SASL negotiation.

The frontend must respond with a [SaslResponse] message.

SaslFinal(AuthenticationSaslFinal)

SASL authentication has completed with additional mechanism-specific data for the client.

The server will next send Authentication::Ok to indicate successful authentication.
