Help configure Shibd in a proxy

    Hi.

    I’m trying to add shibbolth authentication to a service but I’m having some issues.

    I will try to explain my problem.

    I have a machine where wordpress is and I will call it as WPSERVER
    The machine is under a proxy server and it will be PXSERVER

    The WPSERVER RESPONDS AS PXSERVER i.e when someone types PXSERVER/ABC the machine that handles the request is indeed WPSERVER/ABC but as HOME and SITEURL are defined as PXSERVER it will respond as PXSERVER/ABC.

    We are trying to add a shibboleth authentication and have configured our shibboleth2.xml accordingly but we’re having some problems, specially the entityID mapped is different form the Bindings in the SP Metadata.
    Examples: entityID is PXSERVER/sp/shibboleth
    <init:RequestInitiator xmlns:init=”urn:oasis:names:tc:SAML:profiles:SSO:request-init” Binding=”urn:oasis:names:tc:SAML:profiles:SSO:request-init” Location=”https://WPSERVER/sp/Shibboleth.sso/Login”/>
    </md:Extensions>

    or
    Binding=”urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST” Location=”https://WPSERVER/sp/Shibboleth.sso/SAML2/POST”

    Can someone give some help as I don’t know what we are doing wrong?

    Note: I tried a differen RequestMapper and an ApplicationOverride with no effect.
    If I remove the proxy and define HOME and SITEURL AS WPSERVER works as it should but that is not what we want.

    Thanks in advance.

    The WPSERVER should be configured to think that it’s the PXSERVER.

    In the WPSERVER configuration (assuming httpd), you’ll probably want something like:
    ServerName PXSERVER
    UseCanonicalName On

    And none of the Shibboleth configuration in /etc/shibboleth/ should reference WPSERVER

    For now, I’m marking this as resolved, but please let us know if that doesn’t work.

    Hi.

    thanks for the answer.

    After adding the post I relaized I’ve missed
    UseCanonicalName On

    And after that It worked. Shame on me. Only after awhile I saw my mistake.
    And thanks for the quick reply.

    Greets.
