Invalid signature in Request while trying to configure when trying to configure ForgeRock as SAML IDP

When tried to integrate any external IDP for their SAML like Forgerock they get an error saying ForgeRock "Invalid signature in Request".

Issue: When tried to integrate any external IDP for their SAML like Forgerock they get an error saying ForgeRock "Invalid signature in Request".


Root Cause: This is due to the Signature validation present in the IDP server side.


Resolution:
ForgeRock or any other IDP has to disable the signature validation to bypass this to work properly.
