Re: [keycloak-dev] Kerberos, login with different user
by Michael Gerber
I don't like this approach if the "Account Chooser" page is only configurable per realm.
Because, I think it is a bit annoying if you always have to go over the "Account Chooser" page.
99% of all uses want to log in with their kerberos credentials, there are only a few people which want to switch their account.
But I think your approach is good, if you can enable the "Account Chooser" page per client and not only per realm.

Don't like this idea.
#1 Users that want to bypass kerberos have to know to logout first so
they can login as a non-kerberos user.
#2 username/password screen would have to have knowledge that kerberos
is turned on and that the user was logged in via kerberos. I'm don't
think this is possible with the current SPI.
Could we not have a selector or something in the authentication flow
that can select which authenticator to use? The selector could even be
allowed to prompt the user for input, so we could implement a "Is this
you" selector.

This one might be easy to do with current SPI although not sure if
kerberos plugin sets some session variables that need to be cleared.
I was assuming that this option would also require user to logout first.
"Is this you" would only be displayed after a logout.
I don't like this "logout required" thing and the logout cookie. What
is the big deal about having a screen "You are already logged in via
Kerberos. Do you want to continue? Or log in as a different user?"
This would be something that is optionally turned on and shown after the
Kerberos/SPNEGO handshake.

Not sure how this is different than "Is this you?".
"Is this you" would simply prompt the user if the user is the user that
previously logged in from that browser.
Account switcher would allow a user to be signed-in to Keycloak with
multiple accounts and provide some mechanism for applications to select
which account. Like GMail and others allow you to be logged-in to
multiple accounts at a time.
Again, this is very similar to the "Is this you?". The steps would be:
1. SPNEGO handshake successful
2. Show account switcher page with kerberos user as only choice.
The only need for a logout persistent cookie is to remember successful
logins.
I would like this approach the best.

We should never have added idp_hint in the first place IMO. It leaks
authentication semantics into applications and also only works if user
is not logged in already.
idp_hint is a good thing. If an app integrates with Facebook, they'll
need to force the user to login via Facebook so they can obtain a
Facebook token.
skip_auth_mech could be implemented in applications as well
but my same
point stands here. It requires applications to be aware of
authentication semantics. It seems that what's being proposed here is
that admins manually add it to the login URL though, but that's just a
horrible idea, period.
skip_auth_mech is the opposite of auth_mechs_required. Something that I
believe SAML has.

Re: [keycloak-dev] Kerberos, login with different user
by Michael Gerber
Ok, I see.
Is there a way to pass an url query parameter through the wildfly adapter into an authenticator?

I don't think the account chooser is a good option. As you say users that login with Kerberos (and have enabled Kerberos for the Keycloak domain) will in 99% cases want to login with Kerberos.
End of the day I don't really like any of these options, and so far Michael is the only person asking for something like this. With that in mind I think it's better that Michael would develop something custom on top of the authenticator spi, rather than us adding this to Keycloak.

List users that have some client roles & be able to search on users custom attributes
by Remi Cartier
Hey there,
Question 1:
I was wondering if there was an existing mechanism to fetch users that have some specific client roles.
My scenario is this one. As a SSO provider, different applications (clients) are created in Keycloak.
A specific user can have roles for some of those clients.
If, in one of my application, I want to list all the users that ‘belongs’ to me (that have roles for my application) how do I do that ?
I don’t want to list all the users and they filter them by some criteria, that would be a very inefficient way to do it. (CPU + Bandwidth)
Question 2:
In the search REST admin endpoint, is there a mechanism to filter on specific custom attributes ?
for example. I created a language attribute for a user. I now want to list all my users with custom attribute language=FR for example, how do I do that ?
Syntax could be :
/search?attribute1=language&value1=FR or
/search?attribute_language=FR
Thank for your time and great work.
Sorry if those questions have already been asked (if so, please, simply point me to some reference without repeating yourself)
Cheers !

Account Chooser Flo
by Bill Burke
I would like to take the Account Chooser approach to the Kerberos bypass
situation. The Flow would be:
1. Cookie - ALTERNATIVE
2. Chooser Flow - ALTERNATIVE
a. Kerberos - OPTIONAL
b. Account Chooser - ALTERNATIVE
c. Forms ALTERNATIVE
i. Username/Password - REQUIRED
ii. OTP - OPTIONAL
* An "accounts used" cookie needs to be optionally set depending on
"remember me" switch. This should be a persistent cookie.
* Account Chooser page is always shown unless the "account used" cookie
is empty and no ClientSessionModel.getAuthenticatedUser is set.
* If selected user == current ClientSessionModel.getAuthenticatedUser
then return SUCCESSFUL
* If selected user != NULL set ClientSessionModel.getAuthenticatedUser,
return ATTEMPTED
* If selected user == NULL clear
ClientSessionModel.getAuthenticatedUser, return ATTEMPTED
* Username/Password Form Authenticator does not display username,
registration, and broker links if getAuthenticatedUser is already set
* An improvement can be made to also perform OTP input on
Username/Password page if a UserModel is already chosen.

Findings about keycloak--Important
by Satyajit Das
Hi Team,
1) I have the keycloak(1.4.0 final) set up in windows OS.
2) I have 2 services that i have secured using keycloak. The services are
registered in keycloak and the respective keycloak.json is placed in
resource folder.
3) When the services are are deployed in Ubuntu OS the authentication works
as expected. by sharing the tokenid
but then the services are deployed in centos machine the authentication
fails.
The error is Invalid token: Token is inactive.
I tried the same setup and the same war files of services on different
instances of centos , we are facing the same issue but the issue is not
replicated on ubuntu different instances.
Please let me know your thoughts.
Regards,
Satya.

Admin REST - User Roles
by Remi Cartier
Hi guys,
first of all, thank you for that great piece of software, it’s amazing !
Now, down to business.
When I do :
keycloak = Keycloak.getInstance(getKeycloakServerURL(), getKeycloakRealm(), getKeycloakRealmAdminUsername(), getKeycloakRealmAdminPassword(), getKeycloakClientId());
for (UserRepresentation userRepresentation : keycloak.realm(getKeycloakRealm()).users().search(null, 0, Integer.MAX_VALUE)) {
log.info(ToStringBuilder.reflectionToString(userRepresentation, ToStringStyle.JSON_STYLE));
}
The information I get does not contain any roles, all the roles related fields are ‘null’. -
{"self":null,"id":"0556717e-ffb9-4c2d-b85b-533d9396f243","createdTimestamp":1443542144845,"username":"admin","enabled":true,"totp":false,"emailVerified":true,"firstName":"first name","lastName":"last name","email":null,"federationLink":null,"serviceAccountClientId":null,"attributes":{key1=[value1]},"credentials":null,"requiredActions":[],"federatedIdentities":null,"realmRoles":null,"clientRoles":null,"clientConsents":null,"applicationRoles":null,"socialLinks":null}
However in the admin interface I have setup roles at each layer : realm, client
The user I am using to do the queries has all the *realm* roles associated.
is there anything else I need to do ?
thank you for your help !

added a keycloak-common module
by Bill Burke
The SAML adapter had some dependencies on classes within keycloak-core.
Unfortunately though, keycloak-core brings in Jackson JSON parser.
So, I split out keycloak-core into keycloak-common and keycloak-core.
PR is pending, but it should be in when the Europeans wake up.
