[keycloak-user] Client not found error in keycloak

Hello, I am currently trying to integrate Celoxis into our SSO provided by keycloak. Celoxis is configured to send SAML requests to our keycloak server. However, after initiating the SAML exchange I get the following error: * The web UI shows "Unknown login requester" * In keycloak CLI, I can see the following "client_not_found" error: 15:53:03,293 DEBUG [io.undertow.request] (default I/O-2) Matched prefix path /auth for path /auth/realms/Demo/protocol/saml 15:53:03,294 DEBUG [io.undertow.request.security] (default task-2) Attempting to authenticate /auth/realms/Demo/protocol/saml, authentication required: false 15:53:03,294 DEBUG [io.undertow.request.security] (default task-2) Authentication outcome was NOT_ATTEMPTED with method io.undertow.security.impl.CachedAuthenticatedSessionMechanism@6c2221a0 for /auth/realms/Demo/protocol/saml 15:53:03,294 DEBUG [io.undertow.request.security] (default task-2) Authentication result was ATTEMPTED for /auth/realms/Demo/protocol/saml 15:53:03,294 DEBUG [org.keycloak.transaction.JtaTransactionWrapper] (default task-2) new JtaTransactionWrapper 15:53:03,294 DEBUG [org.keycloak.transaction.JtaTransactionWrapper] (default task-2) was existing? false 15:53:03,295 DEBUG [org.jboss.resteasy.resteasy_jaxrs.i18n] (default task-2) RESTEASY002315: PathInfo: /realms/Demo/protocol/saml 15:53:03,295 DEBUG [org.keycloak.protocol.saml.SamlService] (default task-2) SAML GET 15:53:03,295 DEBUG [org.keycloak.saml.SAMLRequestParser] (default task-2) SAML Redirect Binding 15:53:03,295 DEBUG [org.keycloak.saml.SAMLRequestParser] (default task-2) <samlp:AuthnRequest xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol" xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion" ID="ONELOGIN_c4606c22-dc34-44a9-86c0-b157a90c8691" Version="2.0" IssueInstant="2019-04-08T13:53:03Z" Destination="https://sso.netguardians.ch:64020/auth/realms/Demo/protocol/saml" ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" AssertionConsumerServiceURL="https://app.celoxis.com/psa/person.Logi...
