wso2dss – WSO2 DSS: How can I set database user and password dynamically in the request without mappings
So WSO2 DSS have the ability to provide dynamic user authentication, which is documented here . You can either give a static mapping configuration, or else provide a Java class implementation to give the mapping dynamically at runtime. So how this works is, it maps the service authenticated Carbon user with the database user. So you will have to use like UsernameToken to be used with the data service, and you will have to provide a user/password when calling the service, which will in-turn be mapped to a database user.
So if this approach is not feasible, and if you really need to provide the user/password in the message payload, then a possibility would be to write an Axis2 handler and inject the current messagess username+password as the username MessageContext property, so internally when we read the username we would be getting the username+password we set earlier in the handler. (I cant really remember if the MessageContext property is username or not, better check it out). So anyways, as Ive mentioned, this information will be later available at DynamicUserAuthenticator#lookupCredentials(String user) methods user parameter. So from there, we can just decode the username/password from that and return it from that method, which will be used when creating the database connections.
