For SASL LDAP authentication, the authentication method name. Communication between the authentication plugin and the LDAP server occurs according to this authentication method to ensure password security. 

These authentication method values are permitted: 

• SCRAM-SHA-1 : Use a SASL challenge-response mechanism. 

The client-side authentication_ldap_sasl_client  plugin communicates with the SASL server, using the password to create a challenge and obtain a SASL request buffer, then passes this buffer to the server-side authentication_ldap_sasl  plugin. The client-side and server-side SASL LDAP plugins use SASL messages for secure transmission of credentials within the LDAP protocol, to avoid sending the cleartext password between the MySQL client and server.
