Installing UserFileLoginModule

In a JAAS.ini file, you specify a module's parameter values with expressions of the form formal-parameter=actual-parameter. The login module UserFileLoginModule supports the following parameters:

debug: true or false. Enable debug logging.

validateUser: true or false. Set to false to disable password validation. This is for use in web deployments where authentication is provided by your application server; see Providing a login module that supports an Event Authority. In such a case, configure userFile to specify users for your application server. This results in the application server performing authentication and the data server handling authorization, in such a way that the application server and the data server obtain user-credentials information from the same file.

userFile: Fully resolved name of the file with user and role definitions

refreshDelay: Time in milliseconds to check for changes to the definition file (userFile). When it changes it is reloaded. This allows new users to be added.

Installing UserFileLoginModulecan affect the data server's authorization behavior. In particular, if you install UserFileLoginModule, the default Scenario authority will provide expanded access to users with the apama_admin role. For such users, it will grant view, edit, and delete access to all instances (in addition to granting such access to Scenario-instance owners).
