When an external Service Provider (SP) canonicalizes authentication requests with the use of inclusive namespaces, a BIG-IP system used as SAML IdP may fail to process such requests. User's SSO will fail with following errors contained in /var/log/tmm: err tmm1[13063]: 014d0002:3: 9c7802e1: SSOv2 Digest from SAML message is invalid err tmm1[13063]: 014d0002:3: 9c7802e1: SSOv2 Error(12) Signature verification failed for SAML Authentication
Users are unable to perform SAML SSO with certain external service providers.
- BIG-IP is used as SAML IdP. - User performs SP-initiated SAML SSO. - External SAML SP sends signed authentication request, in which canonicalization was done with use of inclusive namespaces.
None.
Now BIG-IP APM as IdP SAML canonicalized authentication requests containing inclusive namespaces can be processed successfully.
