rpc_server_authentication_method

rpc_server_authentication_method specifies the security authentication method for the RPC server. You can run commands in the sys tenant to specify an authentication method for each of the client and server.

Description

Example

ALTER SYSTEM SET rpc_server_authentication_method = 'ALL';
ALTER SYSTEM SET rpc_server_authentication_method = 'NONE';

Others:

1. You must configure the rpc_client_authentication_method parameter for the client. For more information about the description and setting of this parameter, see rpc_client_authentication_method.

2. You can configure multiple authentication methods for the server. Separate the authentication methods with commas (,). The value of this parameter is case insensitive.

   ALTER SYSTEM SET rpc_server_authentication_method = 'NONE, SSL_NO_ENCRYPT';
   

3. If the value of the parameter is correctly specified, the specified value is used. Otherwise, the original authentication method is used and the specified value does not take effect. Assume that the original value is NONE. If you run the following command alter system set rpc_server_authentication_method = 'SSL_NO_ENCRYPT, ANY' (the value ANY is beyond the value range), the setting does not take effect. Instead, the original value NONE is used.

4. The type of client allowed for connection varies according to the authentication method configured on the server.

   Authentication method on server	Type of client allowed for connection
   NONE	Old clients that are not upgraded (including unauthenticated clients) New clients whose authentication method is set to NONE
   SSL_NO_ENCRYPT	New clients whose authentication method is set to SSL_NO_ENCRYPT
   ALL	All clients that are allowed in the preceding two cases
