Sergey Beryozkin commented on CXF-5118:
---------------------------------------
Thanks for the clarification. We talked about this case too, please check the
earlier comments.
Let me clarify: the use case that we address with updating JAASLoginInterceptor
is about supporting the case where a low-level transport 2-way TLS
authentication does not provide enough info such as roles and when the mappings
from the certificates to JAAS properties exist.
I see you want to deal with this issue outside of the JAAS scope. This is
possible but it is a different use case/variation. In this case your
interceptor definitely does not have to extend JAASLoginInterceptor.
IMHO Christian;s code is good to go, hopefully with few extra minor
modifications.
The use case you are referring to can be tackled next. I think it will simplify
things a lot.
Lets finish the case of updating JAASLoginInterceptor first
> Create CXF interceptor which will use HTTPS client certificates to create

> 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)
