Note about the documentation - Valid account guessing with the "forgot password" feature in Keycloak
by Tomás García
Hi,
In this url:
http://keycloak.github.io/docs/userguide/keycloak-server/html/auth_spi.ht...
, it says:
"This form *WILL NOT* re-ask the user to enter in an email or username if
the previous email or username did not exist. You need to prevent attackers
from being able to guess valid users. So, if
AuthenticationFlowContext.getUser() returns null, you should proceed with
the flow to make it look like a valid user was selected."
And I totally agree with that, but it doesn't apply to all cases
unfortunately. If the admin enables "User registration", the user
registration form will tell the a possible malicious guy if the email
combinations she's trying already exists, invalidating what the above
paragraph says. And I don't think there's a way to do the same as in the
"forgot password" feature with the registration form, because after
registration, there's an autologin.
Actually it's confusing for users telling them an email was sent event if
it's not... People sometimes can forget that they're not registered in the
Keycloak system, so the "forgot password" feature as it is today will make
them wait forever. At least, sending them an email telling them "You're not
registered. You can register visiting this link." if "User registration" is
enabled or "Ask your admin to register your email in the system" if it's
not, would be definitely better.
Thanks.

Display all password rule failures at once
by Everson, David (MNIT)
Hi,
Our users are User Acceptance Testing a Keycloak secured website. We have defined strong password rules.
Our users reported:
"Staff have requested some modifications to how password validation is presented to the user. Right now if a user submits a password that does not meet all criteria, such as requiring both an Upper case letter and a number, it will not tell you that both are required, just that and Upper case letter is required. When that is added, THEN it will notify you that a number is also needed.
Staff would like the error message to note all issues with the submitted password, or otherwise note somewhere on the Change Password screen what all the criteria for a proper password are, so the user does not have to guess."
We could update the template to include all the rules. That is probably the quickest.
Is it possible for Keycloak to return all the unsuccessful rules when it validates a password?
Thanks!
Dave

Help regarding Picketlink Feature Migration
by Shaun Willows
We are evaluating security frameworks for new application(s) within our organisation. Picketlink provides a number of features that are desirable to us as an organisation. However, as I understand, Picketlink is being migrated into Keycloak, and this process started in March 2015. Is it possible to provide any updates regarding the migration of the following features:
* Picketlink's Java EE integration (particularly its integration with the DeltaSpike security interceptor) is especially useful to us. Will Keycloak provide similar CDI / Java EE integration? The FAQ at http://picketlink.org/keycloak-merge-faq/ indicates that this was planned to be the case, but I cannot see any progress on this issue in the Keycloak Github or JIRA.
* Picketlink's IDM capabilities included a JPA IDM and the ability to easily create new IDMs. How can this be achieved in Keycloak?
* Picketlink's capability to provide custom authenticators and token providers is also useful to us. How can this be achieved in Keycloak?
I appreciate the need to consolidate projects within Red Hat, however as Picketlink is not being actively developed and there is no clear migration path from Picketlink to Keycloak for a number of features, users of both frameworks are left with no interim solution.
Thanks for any help in this regard

Problem Saml IdP
by Sjef Hoeks
Hi,
I'm trying to integrate Keycloak with a SAML SP, but unfortunately it is not working yet. I created a Identity Provider in the admin interface.
I guess the problem is that in the AuthnRequest which is send by a http post to the SP the AuthnRequest contains a NameIDPolicy:
<samlp:AuthnRequest xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol"
....
<samlp:NameIDPolicy AllowCreate="true"
Format="urn:oasis:names:tc:SAML:2.0:nameid-format:persistent"
/>
</samlp:AuthnRequest>
But according to the documentation of the SP I must send
<samlp:AuthnRequest xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol"
....
<samlp:RequestedAuthnContext Comparison="minimum">
<saml:AuthnContextClassRef>
urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport
</saml:AuthnContextClassRef>
</samlp:RequestedAuthnContext>
</samlp:AuthnRequest>
Is this possible with Keycloak? And if so, how can this be done?
Kind regards,
Sjef Hoeks

ClassCastException on UsersResource search API
by Haim Vana
Hi,
We are using KeyCloak 1.9.3, when trying to search a user with the API (usersResource.search) we are getting ClassCastException.
The problem is that KeyCloak resteasy (version 3.0.16) ClientWebTarget is explicitly using ResteasyUriBuilder and at runtime we are getting our Jersey JerseyUriBuilder.
Any idea how to overcome it ? assuming we can't remove the Jersey dependency.
Exception stack trace:
java.lang.ClassCastException: org.glassfish.jersey.uri.internal.JerseyUriBuilder cannot be cast to org.jboss.resteasy.specimpl.ResteasyUriBuilder

SAML request signature
by lrxw
Hi all,
I’m new to keycloak, but managed to set up keycloak (1.9.2) and realm
with a SAML identidy provider. Everything seems fine, but the SAML
Request sent to my IDP is signed with a RSAKeyValue instead of X509Data.
Can anyone help me how to configure keycloak to use a X.509 certificate?
Greetings

Basic auth and Authentication popup
by Dragan Jotanovic
Hi there,
I have a war application deployed to tomcat that is currently secured with
BASIC authentication through tomcat's realm. When I try to access secured
page, the authentication popup appears.
I would like to switch to keycloak securitu but I'm not sure if it is
possible to configure keycloak to force this authentication popup.
I tried setting it up but when I try to access the secured page, instead of
authentication popup I am redirected to keycloak page "Client is not
allowed to initiate browser login with given response_type. Standard flow
is disabled for the client."
I've followed the instructions from
https://github.com/keycloak/keycloak/tree/master/examples/basic-auth and
http://keycloak.github.io/docs/userguide/keycloak-server/html/ch08.html#t...
.
Is it possible to setup tomcat and keycloak so that the authentication
popup would be forced to appear?
Thanks

Re: [keycloak-user] Performance issues with Federation provider enabled
by Thomas Connolly
Hi Marek
I'm working with Fabricio on the federation performance issues with Keycloak.
In answer to your question we are using the latest KC 1.9.7 version (we upgraded this week from 1.9.2).
To give you some indication of the running a gatling direct access login test (results below).
As you can see below in (1) using KC out of the box. Great performance - we saw 110 tx per sec on a 4 core system.
In scenario (2) using a stubbed federator (simply an echo plugin not connecting to any back end services), performance is unacceptable.
1) Not using the federator - Stub federator (disabled) - while 29 tx per second we could easily get to a stable 110 tx per second.
300 Users (hitting single server)
---- Global Information --------------------------------------------------------
> request count 9185 (OK=9185 KO=0 )
> min response time 18 (OK=18 KO=- )

> std deviation 44 (OK=44 KO=- )
> response time 50th percentile 20 (OK=20 KO=- )

> 800 ms < t < 1200 ms 0 ( 0%)
> t > 1200 ms 0 ( 0%)
> failed 0 ( 0%)
2) Stub federator (enabled)- if we brought test down to 12 tx per second (about 90 users) the response times dropped to < 1200 ms response times, however not even close to meeting out acceptance creteria.
300 Users (hitting single server)

This is currently a show stopper for us and is blocking our path to production.
Do you run similar tests and how can we help you optimise the performance?

Tom.

Hi,
what's the keycloak version used? Could you try latest keycloak and
check if performance is still the issue?
