"None"

Remarks

This field is used to authenticate against the server. Use the following options to select your authentication scheme:

• None: No authentication is performed, unless User and Password properties are set in which BASIC authentication will be performed.
• Basic: Basic authentication is performed.
• Negotiate: If AuthScheme is set to Negotiate, the driver will negotiate an authentication mechanism with the server. Set AuthScheme to Negotiate if you want to use Kerberos authentication.
• AwsRootKeys: Set this to use the root user access key and secret. Useful for quickly testing, but production use cases are encouraged to use something with narrowed permissions.
• AwsIAMRoles: Set to use IAM Roles for the connection.
• AwsEC2Roles: Set to use an IAM Role assigned to an EC2 instance for the connection.
• APIKey: Set to use APIKey and APIKeyId for the connection.
• TemporaryCredentials: Set this to leverage temporary security credentials alongside a session token to connect.
