------------------------------------------
Hi Piotr and Steve,
thanks for describing the scenarios. I think it is really good to check the
code against specific scenarios. Especially if they have a high chance of being
relevant to users. I am pretty sure my code can be enhanced to also work with
the scenarios you described.
1. Having two jaas configs. This works if we override the getId of the
interceptor. I plan to set the id to classname + config name. This way you can
add two instances of the jaas interceptor to the same bus or service. One with
a config for certs and one with a config for username / password.
2. Being able to add CallbackHandlerProviders. This should be easy by adding a
new method addCallbackHandlerProviders(List<CallbackhandlerProvider>). The
reason why I clear the list in the set method was that I want people to be able
to completely change the defaults too but as you correctly identified simply
adding new providers is probably the more common case. So it makes sense to
support both.
[~sergey_beryozkin] I will make sure to provide the name to keep the old
behaviour.

> Use case:
> The user authenticates against the webservice using an X509 client
> certificate. In case of successful authentication the JAAS security context
> should be populated with a Subject that stores the user name and the roles of
> the user. This is necessary to support Authorization at a later stage.
> Design ideas
> The SSL transport will be configured to only accept certain client
> certificates. So we can assume that the interceptor does not have to do a
> real authentication. Instead it has to map from the subjectDN of the
> certificate to the user name and then lookup the roles of that user. Both
> then has to be stored in the subject's principles.
> The mapping could be done inside a JAASLoginModule or before. Inside will
> give the user more flexibility.
> The next step to retrieve the roles should be done in one of the standard
> JAASLoginModules as the source of the roles can be quite diverse. So for
> example the LdapLoginModule allows to retrieve the roles from Ldap. At the
> moment these modules require the password of the user though which is not
> available when doing a cert based auth.
> So I see two variants to retrieve the roles:
> 1. Change the loginmodules like the LDAP one to be configureable to use a
> fixed ldap user for the ldap connect and not require the user password. So
> the module would have two modes: a) normal authentication and group gathering
> b) use a fixed user to just retrieve roles for a given user
> 2. Store the user password somewhere (e.g. in the mapping file). In this case
> the existing LDAPLoginModule could be used but the user password would be
> openly in a text file
> 3. Create new LoginModules with the desired behaviour (fixed user and only
> lookup of roles)
