<p style="margin: 10px 0 0 0">Sorry for the late reply. </p>
<p style="margin: 10px 0 0 0">>We may find that it's more effective to think generally here, not prematurely focus on the IdPAttribute case, and it may be that the proxying use case is better handled by just capturing an entire incoming SAML assertion in a custom Principal, and operating on that, rather than by decomposing it</p>
<p style="margin: 10px 0 0 0">That is the closest to what I implemented for my custom principal. Hide all of the incomming attributes in a principal which contains a Map object. I prefer it over always requring an attribute per object because some things you might want to tear apart in advance like an X509 cert. </p>
<p style="margin: 10px 0 0 0">My issue is that I wanted a special prefix of the names in the encoders since I didn't want them to overlap names from regular ldap, or in the encodered saml2 names, If I could have done it in my code, or explicitly in the AttributeResolver if I could have done it programmatically I would have done something like "https://mysite.com/attributes/$</p> {ATTRNAME}
<p style="margin: 10px 0 0 0">" as the saml2 encoder.</p>
<p style="margin: 10px 0 0 0">The other way to look at this is that my use case is too specific to be generally useful instead add a bean to a new PrincipalDataConnector which allows it to create its own attribute encoders but as a separate step after extracting and possibly renaming the attributes.</p>
