Issue
The SecurID Access Cloud Authentication Service offers two ways to configure an Identity Provider (IdP) for SAML applications:
- Configure the IDR IdP as described in Add a SAML Application.
- Configure the Cloud IdP as described in Add a Relying Party.
The cloud IdP configuration process is simpler (fewer options) while the IDR IdP is more configurable. Configuration differences may not be readily apparent.
Resolution
| Cloud IdP | IDR IdP |
|---|---|
| Creates its own signing certificate | Admin generates and uploads signing certificate |
| Assertion signatures use the SHA-256 hashing algorithm | Assertion signatures use the SHA-1 hashing algorithm by default. Other algorithms including SHA-256 can be configured. |
| Assertion signing is performed on the“Assertion within response” | Assertion signing defaults to “Entire SAML response” but can be configured to be “Assertion within response” |
| The User Identity NameID type is auto-detected | You must specify the User Identity NameID type |
| Extended Attributes are automatically hunted for in all Identity Sources by default | Extended Attributes must be configured with the specific Identity Source where they can be found |
| IdP URL is found only in the IdP metadata file | IdP URL is auto populated in the configuration page |
| 3rd party Service Provider must support SP-initiated SAML | Supports IdP-initiated or SP-initiated SAML |
| Identity Source User Attributes page must have "Synchronize the selected policy attributes with the Cloud Authentication Service" checked. | This checkbox is not applicable |
Notes
The cloud IdP provides primary and/or additional multi-factor authentication for SaaS applications but does not provide single sign-on.
