The parameter AuthenticationProfileUri of DataType String allows the selection of the authentication protocol used by the transport implementation for authenticating access to the specified queue. This maps to the ProfileUri Property in the KeyCredentialConfigurationType instance selected through the ResourceUri and AuthenticationProfileUri Strings.

A set of possible AuthenticationProfileUris are in the Profile http://opcfoundation.org/UA-Profile/Server/KeyCredentialManagement.

If this String is not null or empty, it overrides the AuthenticationProfileUri of the PubSubConnection transport settings defined in 6.4.2.2.2.
