Hello!
I have problem with my SAML validation.
- I already did, that inside the validation i can call an LDAP request,
get the given cert from the LDAP, and check agains the cert in the SAML.
BUT
I need data from the request too. special one of the given claims. I
need that value to giv it into the LDAP query.
How can I get the full request, or at least the SOAP body from the (it
can be any form: stream, string, dom, object...)
org.apache.cxf.ws.security.trust.STSSamlAssertionValidator.validate()
function?
Thanx

It's look like good, just I need data from the request too (a claims)
for the query.

I guess you could do something like override verifySignedAssertion, to
retrieve the certs from your DB using the SAML Assertion:

and then override the verifyTrustInCerts method in the underlying
SignatureTrustValidator:

Hello!
The request contains a SAML in the security header.
This SAML contains a
<saml2:Subject>
<saml2:NameID

<saml2:SubjectConfirmation

</saml2:SubjectConfirmation>
</saml2:Subject>
In the request is an attribute in the claims:
<ns:Claims Dialect="myDialect">
<saml-a:Attribute

xmlns:saml-a="urn:oasis:names:tc:SAML:2.0:assertion"

<saml-a:AttributeValue
xsi:type="xs:string">myOrganizationID</saml-a:AttributeValue>
</saml-a:Attribute>
</ns:Claims>
the certification with which the incomming SAML signed is stored in a
database and for the query I need the saml2:NameID value (MyUserID) and
the "urn:oasis:names:tc:xspa:1.0:subject:organization-id"
organisationID
(myOrganizationID).
I can do this query, but only after the SAML validation is done.
Somehow i need to run the SAML signature validation after I can get the
data (inside the
org.apache.cxf.sts.operation.TokenIssueOperation.issueSingle()
function)
or get the data from the request at the
org.apache.cxf.ws.security.trust.STSSamlAssertionValidator or
org.apache.wss4j.dom.validate.SamlAssertionValidator

Hello!
I study the WSS4J SAML Validator, but not help much, my problem is
need
to get the certificate based of the content of the request and header
SAML (get out the subject, do an query and the query give back the
certificate), and need to validate the SAML with this certificate.
In this case (SamlAssertionValidator) is running before i able to
parse
the request. I can create a dummy validate() function, but after I
need
to somehow call it again.
Any help will welcome.
Thanx
Csaba
Does the SAML assertion appear in the security header of the
request or
in
the body of the request? For the former, you will need to implement
your
own WSS4J SAML Validator, or subclass the existing one in some way:
https://github.com/apache/wss4j/blob/trunk/ws-security-dom/src/main/java/org/apache/wss4j/dom/validate/SamlAssertionValidator.java
If the SAML assertion is in the SOAP Body then it's handled by
the STS
code, so you will need to either replace or override this class:
https://github.com/apache/cxf/blob/master/services/sts/sts-core/src/main/java/org/apache/cxf/sts/token/validator/SAMLTokenValidator.java

Hello!
I have a request with the STS to validate a incoming SAML with a
certificate what come from another source: example need to query it
from
a database, based on the data in the request.
How start it? I know the SAML validation is in the deep and need
the
certificate to be in a truststore. Can I give directly the
certificate
as an attribute or need to create a own, custom truststore manager?
Thanx.
