</p>
<p>
Votre application a peut-être besoin de manipuler de identifiants
utilisateur, dont la valeur est stable d'une session à l'autre ; par
exemple pour gérer les préférences utilisateur. Or, pour des raisons de
protection des données personnelles, les fournisseurs d'identités ne
peuvent vous transmettre les identifiants des utilisateurs. Dans ce cas,
vous pouvez demander aux fournisseurs d'identités de vous communiquer
des identifiants stables mais opaques, appelés <strong>eduPersonTargetedID</strong>.
</p>
<p>
Vous devrez configurer le fichier <em>AAP.xml</em> de votre fournisseur de services Shibboleth comme indiqué ci-dessous :
</p>
<pre><AttributeRule Name="urn:oid:1.3.6.1.4.1.5923.1.1.1.10" Header="Shib-TargetedID" Alias="targeted_id">
<AnySite>
<AnyValue/>
</AnySite>
</AttributeRule></pre>
<p>
L'attribut sera accessible pour l'application dans l'en-tête <acronym title="Hyper Text Transfer Protocol">HTTP</acronym> <strong><acronym title="Hyper Text Transfer Protocol">HTTP</acronym>_SHIB_TARGETEDID</strong> (avec Shibboleth 1.3). Le format du eduPersonTargetedID est le suivant : identifiant_IdP<strong>!</strong>identifiant_SP<strong>!</strong>identifiant_utilisateur <br></p><p><br></p><p>According to their doc, nameid are session based and not user based so if you want stable identifier, you have to ask for eduPersonTargetedID attribute !!<br></p>

Shibboleth only supports transient name ids? I find that hard to
believe. Remember Keycloak would just look like any other client.
IMO you should go that route.<br>
<br>
Also though, I think you might be able to write a Broker Mapper,
take a look at UsernameTemplateMapper. This SPI is undocumented and
unsupported at the moment, but I hope to change that soon.</div><div bgcolor="#FFFFFF" text="#000000"><br>

<div>Hi all, <br>
<br>
</div>
According to shibboleth specification, IdP of a
federation usually use transient NameID which makes
Shibboleth impossible to interface with keycloak, even
if we manage the Discovery Service externally in order
to maintain IdP list mapping between federation and
keycloak.<br>
</div>
It's really annoying for me and I'm trying to
investigate a way to solve this problem.<br>
</div>
In my federation, some doc say that if you need to manage
personnal user information in your application, you have
to rely on a dedicated attribute in order to retreive real
user id and not the transient opaque one. In this case, an
attribute called eduPersoneTargetedId exists and can be
use by shibboleth. <br>
</div>
I am trying to patch the saml broker in order to take into
consideration this attribute in a kind of
attributeToNameIdMapper but I have to admit that I'm lost a
bit in the code.<br>
</div>
Do you think this approach is good ?<br>

<div>Hi Bill, all, <br>

In the case of a transient only nameid, would it be
possible to create a dedicated attribute mapper in order
to use for exemple the email attribute as name
identifier ?<br>
<br>

PS : the urn:mace:shibboleth:1.0:nameIdentifier is in fact
use in SAML v1 for request a nameid that is transient
