I followed the above documentation on configuring the SAML with a Google SAML app. Logging into Kibana with SAML works now, but I'm having issues with the SAML authentication for Enterprise Search. This is the response received when trying to log into Enterprise Search through SAML:
{"statusCode":401,"error":"Unauthorized","message":"Unauthorized"}
Upon inspecting the SAML request/response, all of the fields and attributes are the same as the SAML for Kibana. I made sure to specify the settings for the Enterprise search node ("User Setting Override") as noted in the documentation.
elasticsearch.yml User Setting Overrides:
xpack:
security:
authc:
realms:
saml:
google-saml-realm:
order: 2
attributes.principal: "nameid"
attributes.groups: "groups"
idp.metadata.path: "[URL TO METADATA]"
idp.entity_id: "https://accounts.google.com/o/saml2?idpid=xxxxxxxxx"
sp.entity_id: "[KIBANA ENDPOINT]/"
sp.acs: "[KIBANA ENDPOINT]/api/security/v1/saml"
sp.logout: "[KIBANA ENDPOINT]/logout"
enterprise-search.yml user Setting Overrides:
ent_search.auth.google-saml-realm.source: elasticsearch-saml
ent_search.auth.google-saml-realm.order: 1
ent_search.auth.google-saml-realm.description: "Google SAML login"
ent_search.auth.google-saml-realm.icon: [URL TO ICON]

In addition, here are the SAML payloads for each Kibana and Enterprise Search SAML POST request:
Kibana (returns 302):
