Describe the issue

Trying to use SAML with Keycloak as IdP, authentication is valid and SAMLResponse is valid but caddy reports failed to ParseXMLResponse: Authentication failed

Configuration

Paste full Caddyfile below:

{
	debug

	servers {
		trusted_proxies static 0.0.0.0/0
	}

	order authenticate before respond
	order authorize before basicauth

	security {
		saml identity provider keycloaksaml {
			realm keycloaksaml
			driver generic
			idp_metadata_location /etc/caddy/descriptor.xml
			idp_sign_cert_location /etc/caddy/cert.pem
			idp_login_url https://xxxh/auth/realms/xxx/protocol/saml/clients/caddy
			application_name "Caddy Auth Test"
			application_id "caddy-saml"
			entity_id "https://xxx/auth/realms/xxx"
			acs_url http://web.test.svc.cluster.local/auth/saml/keycloaksaml
		}


		authentication portal authz_proxy_portal {
			crypto key sign-verify {env.CRYPTO_KEY}
			# enable identity provider keycloak
			enable identity provider keycloaksaml
			cookie lifetime 3600
			cookie samesite lax
			cookie insecure on
			transform user {
				match realm keycloaksaml
				action add role authp/user
			}
		}

		authorization policy default_authz_policy {
			#disable auth redirect query
			set auth url /auth/saml/keycloaksaml
			crypto key verify {env.CRYPTO_KEY}
			allow roles authp/user
		}
	}
}

:80 {
	root /opt/www

	log {
		output stdout
		format transform "{common_log}"
	}

	route /auth/* {
		authenticate with authz_proxy_portal
	}

	route {
		authorize with default_authz_policy
		templates
		try_files {path}.html
		file_server
	}
}

Hi, any idea how to resolve?

webfrank avatar Sep 14 '25 12:09 webfrank

@webfrank , no really, because i can’t replicate your environment. The parsing makes certain assumptions that seem to be not true in your environment. You would need to dive deep on this one.

Hi, the issue is with the parsing of SAMLResponse but the response is a valid SAMLResponse, generated by Keycloak and SAML integration with Keycloak works with DEX, for example. There should be something in the SAML parser lib which is breaking, can you investigate as I do not have the full knowledge of SAML?
