Has any body integrated CA SSO with API developer portal with SAML flow. We have integrated Siteminder with API developer portal with Siteminder as IDP and developer portal as SP on the API gateway. IDP initiated SSO works fine but has cache active in browser even though . The SP initiated flow is not working and fails with http 400 error and we are seeing errors in CA Webagent option pack logs which says" SAML request not encoded properly". Im working with CA support to reproduce the issue. If anybody has a working flow for SP initiated SSO with siteminder can you please share or has anybody faced this.
