Subject [jira] [Commented] (CXF-5118) Create CXF interceptor which will use HTTPS client certificates to create JAAS SecurityContext
Date Fri, 01 Aug 2014 14:22:38 GMT

    [ https://issues.apache.org/jira/browse/CXF-5118?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14082278#comment-14082278

Sergey Beryozkin commented on CXF-5118:
---------------------------------------

And IMHO this code will be easier and simpler customize if CertificateMapper is introduced.
I do not see much differences between our approaches.
In you case: we do a default mapping and then get a a password via a non standard callback
class.
In my case: we do a customizable mapping (and your code would move to the default mapper thus
cleaning up JAASLoginInterceptor), get a password as part of this mapping too and NamePasswordCallback
can be reused

> 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)
