Piotr Klimczak commented on CXF-5118:
-------------------------------------
I think that quite common scenario of this functionality usage may be not to
use JAAS at all for it.
Just do some LDAP lookup to retrieve roles and that is all.
So this is why it should be separated to JAAS, but possible to use JAAS simply.
In many companies with high security level, nobody would agree to use passwords
or decrypt passwords (in fact, decrypting may not be possible in many cases,
for example when passwords are simple hashed).
Password-less login may also look strange for them, so developers/architects
may have a problem after 1st audit.
So they should simply got to basic role retrieval functionality.
We should not close this path for them. Otherwise it will not be usable for
them.

> 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)
