Configuring IdP Initiated SSO

[stevejarman]

Hi - I am urgently trying to locate the documentation or some sort of guide for configuring IdP Initiated SSO with ServiceNow. Are you able to tell me if that documentation exists, and - if so - where to find it?

How can I configure serviceNow as IDP ?

Thanks guys - I've configured SSO in the "standard" (?) way in ServiceNow. i.e. the result is that you visit the ServiceNow login page, select "External Login", and then you're sent off to authenticate.

What I'm specifically trying to figure out are the differences in configuration when the SSO authentication is initiated at the IdP end. i.e. when the user arrives at the ServiceNow instance PRE-authenticated. I haven't been able to find anything specific to that, or been able to get it working just by making it up as I go along.

Does anyone know specifically what needs to be done differently in that case?

You will have to perform below steps to configure SSO on instance

- Get PEM certificate and create record for x509 certificate.

- Create IDP provider and refer this certificate.

Check correct values are set for below system proerties for idp

glide.authenticate.sso.redirect.idp - sys_id of idp

glide.authenticate.sso.saml2.idp_authnrequest_url - Your federation URL for authentication

glide.authenticate.sso.saml2.idp_logout_url - Logout URL

Also, make sure that single sign is turned on .
