[keycloak-user] SAML Token contains carriage returns (&#xD)

[Dean Peterson]

Is there a way to remove the carriage returns keycloak uses in the saml
assertion token? This is incompatible with Websphere idAssertion using
keycloak as the Identity provider. Ex, notice the &#xD characters in the
content:
