> In the past we used "/idp/logout.jsp" to implement SAML Logout. But that doesn`t seam to work anymore. If we call this URL we get a 404 Error.

As specified [in the docs](https://gluu.org/docs/ce/3.1.4/operation/logout/#saml-logout), please now use:
`https://[Gluu_Server_hostname]/idp/Authn/oxAuth/logout`
> Now my question is do I have to install an Shibboleth SP using this Doc ?
Why would you need to install the Shib SP? The SP is a web filter to secure the app.. if your app is already supporting SAML, then there's no need to use the Shib SP, it was just used for the purpose of the demo.
