Federation SAML Source Property Mapping

[katrinm86]

Describe your question/
So I want to hook up my Authentik instance to a SAML IdP source for federated login.

I checked the following documentation pages

• https://docs.goauthentik.io/docs/users-sources/sources/protocols/saml/
• https://docs.goauthentik.io/docs/users-sources/sources/property-mappings/

and tried following the "see documentation for a list of all variables" link in the "SAML Source Property Mapping" which points to a non-existing page "https://version-2024-12.goauthentik.io/docs/user-sources/sources/property-mappings/expressions?utm_source=authentik"

but I'm not really seeing how one is supposed to do the attribute mappings.

Is it really required to write your own lookup code for each property like it is done for "name_id" (https://github.com/goauthentik/authentik/blob/main/authentik/sources/saml/processors/response.py#L209)?

Am I something missing?

Thanks

The latest link is https://docs.goauthentik.io/docs/users-sources/sources/property-mappings/expressions. @tanberry let's check we're linking probably from the UI

As for the source property mappings code themselves, yes, you need to write whatever you want in there, allowing you to get as much customization as needed
