Correct setup of clientID
by Helio Frota
Hi,
1. Is correct to manually add clientID on keycloak.json ?
2. I found this email from archives:

clientId is now called 'resource' ?

tomcat 7 SAMl adapter and <login-config> question
by David Guerra
Hi,
I am updating an old struts 1.3 web app and integrating our SAML - SSO
service with help of keycloak adapter for SAML.
I have some issues with that development on Tomcat 7: in the "web.xml"
file, the following lines are suppose to be add
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>this is ignored currently</realm-name>
</login-config>
Reading the other options, in the Wildfly the following code must be add:
<login-config>
<auth-method>KEYCLOAK-SAML</auth-method>
<realm-name>this is ignored currently</realm-name>
</login-config>
And, googling a like, I found that, on Tomcat 7, the correct configuration
must be:
<login-config>
<auth-method>KEYCLOAK</auth-method>
<realm-name>this is ignored currently</realm-name>
</login-config>
My question is: "BASIC" for tomcat 7 and SAML adapter is correct for my
development?
Thanks!!!

Revoking individual refresh tokens
by Peter Nalyvayko
Hello,Is there a way to revoke/invalidate a refresh token issued to a specific user? My understanding is that I can revoke all of the previously issued refresh tokens using 'Revocation' and setting Not Before to Now; this is good but it would be great if I can revoke individual tokens as well.Thx--Peter

impossible to get logs from adapter-saml
by David Guerra
Hi,
I am updating an old struts 1.3 web app and integrating our SAML - SSO
service with help of keycloak adapter for SAML.
I am facing a problem (perhaps a silly problem): I am using Tomcat 7 and I
try to get logs from the keycload saml adapter as said in:
http://keycloak.github.io/docs/userguide/saml-client-adapter/html/debuggi...
with "log4j.logger.org.keycloak.saml=DEBUG" in my log4j.properties.
But there are no 'debug' info in the console. I have other debug info for
my application bat none for keycloak adapter.
I am doing something wrong?
Thanls for the help.

Custom page for not found realm (tenant)
by Haim Vana
Hi,
We are using KeyCloak with multi-tenancy, each realm represents a tenant (customer).
Sometimes due to setup issue or typo in the realm name we are getting 404 page, is there a custom page or a way to customize a page for missing realm scenario ?
For example something like - Realm <name> doesn't exist...
Thanks,
Haim.

Can't access admin console with realm admin (from 1.9.4 version and above)
by Haim Vana
Hi,
>From version 1.9.4 and above I can't access the admin console with realm admin user.
The realm admin user is a specific realm admin, it was created in the master realm and his only roles are the client (the realm) roles.
I am getting the below exception and it look like it's not a bug (see RealmsAdminResource.java line 114), if so how am I supposed to create an admin only for a realm ?
Also what about realm admins created in versions 1.9.3 could they still access the admin console if KeyCloak will be upgraded ?

Re: [keycloak-user] Email internationalization
by Stian Thorgersen
If you change the PR to use MimeMessage#setSubject(subject, charset) we
should just add it. It's better to have it just work rather than require
changing default system encoding or using -Dfile.encoding.

keycloak javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
by jazz
Hi,
I have wildfly 10 installed using nginx as https proxy server [1,
standalone-full.xml]. Works great when using weak ciphers in nginx. In
that case keycloak can connect back to the app after authentication
(redirect SSL). When using strong ciphers in nginx [2] is fails the ssl
handshake [4]. JCE seems enabled since the deployed app reports 2016-
04-13 21:41:33,304 INFO [stdout] (ServerService Thread Pool -- 83) max
allowed keylength = 2147483647
My question is: does keycloak use a limited set of ciphers? SNI works
fine according to the log. I was digging in the code, but could not
find something obvious [5]
Best regards, Jazz

How to get specific client role programmatically
by Haim Vana
Hi,
I am using the KeyCloak API to create admin users and update their roles, I am able to add to an admin user all the available client roles, however how can I add a specific one ?
This is my code to get all the available client roles:
userResource.roles().clientLevel(userRealmClientId).listAvailable()
How can I get specific one and not all ?
Any advice will be appreciated,
Haim.

Performance issues with Federation provider enabled
by Fabricio Milone
Hi all,
I've been running load tests on our application during the last few weeks,
and having some performance issues when my custom federator is enabled.
The performance issue does not exist when the federator is disabled.
*Configuration*:
I have a cluster of 2 instances of Keycloak, with a standalone DB, we've
verified the DB isn't an issue when the federator is disabled. Both
instances have a quad core CPU and they are in the same network. We’ve left
the memory at 512MB. The test script, database and API that connects to the
federator are in separate machines.
*Federator*:
We have a simple custom federator that makes calls to a very performant
api, which has been tested and is ok. Additionally, we've tested stubbing
the API so the performance is not a problem there. This federator is using
a jaxb marshaller to create a request, again tested in isolation and is
performing well.
As the federator is doing a lot of calls to the API (3 per login request),
I've implemented a httpclient that uses a
PoolingHttpClientConnectionManager with 1000 connections available to use,
instead of using the standard apache httpclient from http components. That
hasn't improved a bit the performance of the system.
*Tests*:
It is a gatling scala script that could generate around ~300 (or more)
requests/second to the direct grants login endpoint using random usernames
from a list (all of them already registered using KC). The script is doing
a round robin across both instances of Keycloak with an even distribution
to each KC instance.
The idea is simulate a load of 300 to 1500 concurrent users trying to login
into our systems.
*Problem*:
If I run the tests without using a federation I can see a very good
performance, but when I try to run the tests with the custom federation
code, the performance drops from ~150 requests/second to 22 req/sec using
both instances.
Memory wise, it seems to be ok. I've never seen an error related to memory
with this configuration, also if you take a look at the attached visualVM
screenshot you'll see that memory is not a problem or it seems not to be.
CPU utilisation is very low to my mind, I'd expect more than 80% of usage
or something like that.
There is a method that is leading the CPU samples on VisualVM called
Semaphore.tryAcquire(). Not quite sure what's that for, still investigating.
I can see that a lot of new threads are being created when the test starts,
as it creates around 60requests/second to the direct grants login call, but
it seems to be a bottleneck at some point.
So I'm wondering if there is some configuration I'm missing on Keycloak
side that could be affecting the cluster performance when a federator is
enabled. Maybe something related to jpa connections, infinispan
configuration or even wildfly.
I'd really appreciate your help on this one as I'm out of ideas.
I've attached some screenshots of visualVM and tests results from my last
run today.
Sorry for the long email and please let me know if you need further
information.
Thank you in advance,
Regards,
Fab
