Typically it is recommended to deploy the following Blueprint context in order to enable a JAAS PropertiesLoginModule shipped with Karaf:
and here is a typical pom.xml:
Such a bundle is generic and will work with any service depending on PropertiesLoginModule.
It would be nice if Karaf itself shipped such a bundle and offered an optional feature, tentatively named 'karaf-jaas-login-properties' (or similar) so that whenever a user want to work with PropertiesLoginModule all he/she needs to do is to modify etc/user.properties and do 'features:install karaf-jaas-login-properties'.
Note it is not a new enhancement request but simply a wish to get the default properties login module easily enabled when needed
