[keycloak-user] Can't invoke Keycloaks OpenID Connect token endpoint with grant type set to password

[Nicolas DUMINIL]

Hello,

 

I'm following this blog (
<http://blog.keycloak.org/2015/10/getting-started-with-keycloak-securing.htm
l>
http://blog.keycloak.org/2015/10/getting-started-with-keycloak-securing.html
) to secure some jax-rs services. I have the following client:

 

./keycloak/bin/kcadm.sh get clients/f3c2109d-9eb0-4fb3-b6be-32a52a691d42 -r
demo-realm

{
  "id" : "f3c2109d-9eb0-4fb3-b6be-32a52a691d42",
  "clientId" : "curl",
  "surrogateAuthRequired" : false,
  "enabled" : true,
  "clientAuthenticatorType" : "client-secret",
  "redirectUris" : [ " <http://localhost> http://localhost" ],
  "webOrigins" : [ ],
  "notBefore" : 0,
  "bearerOnly" : false,
  "consentRequired" : false,
  "standardFlowEnabled" : true,
  "implicitFlowEnabled" : false,
  "directAccessGrantsEnabled" : true,
  "serviceAccountsEnabled" : true,
  "authorizationServicesEnabled" : false,
  "publicClient" : true,
  "frontchannelLogout" : false,
  "protocol" : "openid-connect",
  "attributes" : {
    "saml.assertion.signature" : "false",
    "saml.force.post.binding" : "false",
    "saml.multivalued.roles" : "false",
    "saml.encrypt" : "false",
    "saml_force_name_id_format" : "false",
    "saml.client.signature" : "false",
    "saml.authnstatement" : "false",
    "saml.server.signature" : "false",
    "saml.server.signature.keyinfo.ext" : "false",
    "saml.onetimeuse.condition" : "false"
  },
  "fullScopeAllowed" : true,
  "nodeReRegistrationTimeout" : -1,
  "protocolMappers" : [ {
    "id" : "5916961f-e222-4a6d-968e-ca2031961168",
    "name" : "family name",
    "protocol" : "openid-connect",
    "protocolMapper" : "oidc-usermodel-property-mapper",
    "consentRequired" : true,
    "consentText" : "${familyName}",
    "config" : {
      "userinfo.token.claim" : "true",
      "user.attribute" : "lastName",
      "id.token.claim" : "true",
      "access.token.claim" : "true",
      "claim.name" : "family_name",
      "jsonType.label" : "String"
    }
  }

 

I'm doing the following curl request:

 

curl --data
"grant_type=password&client_id=curl&username=customer-manager-user&password=
toto"
<http://localhost:18080/auth/realms/master/protocol/openid-connect/token>
http://localhost:18080/auth/realms/master/protocol/openid-connect/token

 

and I get the following error:

 

{"error":"unauthorized_client","error_description":"UNKNOWN_CLIENT: Client
was not identified by any client authenticator"}

 

The user "customer-manager-user" is as follows:

 

[jboss at ca385990f977 ~]$ ./keycloak/bin/kcadm.sh get users -r demo-realm -q
username=customer-manager-user      
[ {
  "id" : "52f6b73c-0982-415d-9157-a4735bf619b1",
  "createdTimestamp" : 1513861722307,
  "username" : "customer-manager-user",
  "enabled" : true,
  "totp" : false,
  "emailVerified" : false,
  "disableableCredentialTypes" : [ "password" ],
  "requiredActions" : [ ],
  "notBefore" : 0,
  "access" : {
    "manageGroupMembership" : true,
    "view" : true,
    "mapRoles" : true,
    "impersonate" : true,
    "manage" : true
  }
} ]

 

I have googled in order to find a solution and I found several persons
reporting the issue but I didn't find any solution. Many thanks in advance
for any help.

 

Kind regards,

 

Nicolas
