    I’m trying to setup OpenAM for use in an IDP initiated flow.
    A 3rd party IDP will send a SAML Assertion which needs to be validated.
    After verifying the assertion, I need to retrieve additional information about the caller and target application and finally call an internal service to generate a session for the user in the target application.
    I need to redirect the user to a custom URL based on values received in the request
    To begin with, I tried the following setup in OpenAM with no success
    Registering a remote IDP (metadata file below)
    Hosted SP
    After that, I have tried to call http://localhost:9000/openam/idpssoinit?metaAlias=null&spEntityID=/sp, along with a SAML assertion in the request body. (The other thing that I have noticed is that in case of a remote IDP Provider the metaAlias field in OpenAM is blank. Is this how its supposed be or is there a screen where we can add the details?)

    I receive the following error message “HTTP Status 400 – Error processing AuthnRequest. Error retrieving metadata”.

    Looking into the source code, it seems that only hosted IDPs can be used in IDP initiated SSO.

    I’m not entirely sure I have OpenAM setup correctly to fulfill my requirements. Could someone please suggest how I should proceed.

    IDP metadata file

    <EntityDescriptor xmlns=”urn:oasis:names:tc:SAML:2.0:metadata” entityID=”idp”>
    <IDPSSODescriptor WantAuthnRequestsSigned=”false” protocolSupportEnumeration=”urn:oasis:names:tc:SAML:2.0:protocol”>
    <KeyDescriptor use=”signing”>
    <ds:KeyInfo xmlns:ds=””&gt;
    <SingleSignOnService Binding=”urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST” Location=”http://localhost:8090/SAMLWeb/openam/SSOPOST/metaAlias/idp”/&gt;
