The ALTERNATE_AUTH_ENC database manager configuration parameter specifies the encryption algorithm that is used to encrypt user ID and password that are sent from the client during a connect or attach. This parameter is in effect when the authentication method that is negotiated between the client and the server is SERVER_ENCRYPT.

It is recommended to set this parameter to AES_ONLY.


If this parameter is set to a value other than AES_ONLY, the server can accept the DES encryption algorithm to encrypt the user credentials and DES is cryptographically weak in comparison to AES.

This control is used in the following benchmarks:


To deliberately skip this control (e.g. meaning don’t use Puppet to enforce this setting), we provide you with three ways:

1) Add db2_secured::controls::database_manager_configuration_parameter_alternate_auth_enc: skip to your hiera data. This will skip this control for ALL databases.
2) Add db2_secured::controls::database_manager_configuration_parameter_alternate_auth_enc::instance_name::dbname: skip to your hiera data. This will skip this control for specified database only.
3) Add an entry with the content database_manager_configuration_parameter_alternate_auth_enc to the array value db2_secured::skip_list in your hiera data.


Attribute Name Short Description
title The database identifier to apply the control to.


The database identifier to apply the control to.

All controls need an database identifier to apply the control to. Here is a simple example:

db2_secured::controls::control_name { 'db2inst1/MYDB':}

In this example, the string dbinst1 is the instance, the string MYDB is the database to apply the control to.
