While trying to achieve pure Keycloak IDP initiated sso to achieve this flow
"Login to keycloak realm ==> Go to applications ==> click on application name and application launches because you are already logged in to the keycloak IDP),
I faced several issues while trying to achieve the above flow, so I gave that up, and now trying to achieve Keycloak brokered sso:
(Browse to the specific Keycloak broker URL ==> Get redirected to the login page of the Keycloak IDP ==> this does a POST of Saml assertion to my application URL ==> Application launches because the user is already logged in / authenticated with IDP).
I am using one instance of Keycloak as IDentity provider (keycloak3) and another instance as Service Provider (keycloak4).
I am following the steps from this existing thread.
idp initiated sso using keycloak
########## Start Steps followed ##########
a. create a saml client at keycloak3 (http://localhost:8083) under realm3. With IdP initiated SSO Name set as some name without spaces) --> say, sso.
b. In the Fine Grain SAML Endpoint Configuration section of the above client, for Assertion Consumer Service (ASC) POST Binding URL --> http://localhost:8084/realms/realm4/broker/saml/endpoint/clients/keycloak4samlclient ( https://www.keycloak.org/docs/latest/server_admin/index.html#idp-initiated-login)
c. click on above created saml client --> installation --> Export SAML Metadata IDPSSODescriptor and save as saml-metadata.xml ( say ).
d. Add a user in keycloak3, say user3/user#456
e. At the keycloak4(http://localhost:8084), create a IDP ( identity providers tab with name saml (refer ASC url). Import the above exported saml-metadata.xml and save.
f. At the keycloak4, create a saml client and in the IDP initiated SSO url give name as keycloak4samlclient
g. In the browser hit, http://localhost:8083/realms/realm3/protocol/saml/clients/sso
Prompt for username/pwd, give credentials for user3
########## End Steps followed ##########
My application is the 'java-saml' application deployed on local tomcat at 8080.
https://github.com/SAML-Toolkits/java-saml/tree/master/samples/java-saml-tookit-jspsample
After I complete all the steps, and browse this URL
http://localhost:8083/realms/realm3/protocol/saml/clients/sso
I am getting "client not found" error. I spent the entire day troubleshooting this one, could not find any leads. Can someone please let me know if you have faced this, and whether you have any solution I can try? This is the screenshot of error.
Error Message: Client not found
I have a query about how keycloak is supposed to be working with client without GUI access.
Basically I have:
A keycloak server configured with a realm, clients(Access type confidential) and Users
A server application with a GUI that also provide API, secure with keycloak (client, user, blablabla)
This is kind of working already as I am able to log on the GUI, have the redirect, etc..
Even accessing the APIs works well, when I have access to a GUI: I log on my UI, follow the redirect and get my UI to display the token. The the human (to differentiate the user from an application), can use the token in any API client.
In this context the user never sees the client secret, which is instinctively the right way. (note that I am very opened to people telling me my instinct is wrong!)
What I am NOT able to do so far is to find the way a server application (without GUI) can get a valid token?
The authorization_endpoint, as far as I understand it, requires both the client id and the client secret) to get a token, which I would rather avoid: I don't think giving my client secret to all my "customers" is the proper way to do it.
Alternatively I could create an API on my client that woudl ask for user credential and ask for the token in its behalf, but that would expose the clients credentials to my application, which is against the whole concept!
I tried setting my client Access type as public, but when I use the API call below I also get a error:
POST /auth/realms/realmname/protocol/openid-connect/tokenAPI
'grant_type=client_credentials'
'client_id=client_id'
'username=username'
'password=password'
{
"error": "unauthorized_client",
"error_description": "Public client not allowed to retrieve service account"
}
Would anyone know how this is supposed to be done ?
Thanks in advance.

(...) A server application (without GUI) can get a valid token... typically using the Client Credentials flow.
But we would define in this case a dedicated Client for your server (client?) application to authenticate against. The returned token (not bound to a specific user) will serve for authorizations on allowed applications (i.e. your classic GUI or API clients).
So, basically you should (in very short):
define a specific confidential Client in your Keycloak
add the desired applications (or other Clients) to the Client Scope(s). Those you want to authorize transitively from this Client.
authenticate against this Client with Client Credentials flow (given the token endpoint, client id, credentials, scope)
ensure that you are authenticating through TLS and that parameters are included in request body (and not in headers - for enhanced privacy)
further harden security of your Client(s)
When you do not want anymore this particular server (client?) application to access your applications, you can change the corresponding "authentication" Client's secret/credentials or simply delete it.
"I don't think giving my client secret to all my "customers" is the proper way to do it."
You are right and the proposed method above strictly avoids that. Each customer would have its own credentials.
EDIT
(adding more details)
By performing as above, you would end up with the following scheme:
Flow Keycloak Server
C/S app. or Customer X <--- Client Creds ---> Auth. Client X
--- Access Token ---> Appl. Client <--> Appl. Server
C/S app. or Customer Y <--- Client Creds ---> Auth. Client Y
--- Access Token ---> Appl. Client <--> Appl. Server
Browser users <--- Standard ------> Appl. Client <--> Appl. Server
Note: this is not a detailed flow chart. Arrows mostly show relationships here.
Finally, please note that the terminology may differ a little here, but the proposed method is basically the same that Google uses. So you may aswell take some inpiration from there:

I just had the same problem some weeks ago
In my case, I have a backend API and a frontend application that the users can use.
Eventually, I can't share the client_secret to the frontend application.
So here is my solution:
On keycloak, create a client (ex front_end_client) with grant type public
This client is going to be used by the frontend application to authenticate users using implicit flow (with PKCE will be more secure)
On keycloak, create a second client (On the same REALM as the first client) with grant type confidential, this client is going to be used by the backend API
Now, this is how it works:
Frontend app authenticate users and get the access token (Using the font_end_client)
The frontend app sends this token for every request to the backend
Backend app verify this token, and can retrieve permissions from it
What I want to do is this:
I have keycloak integrated with my application. So when my app is launched , keycloak login page is shown to user. Now , I am trying to provide an option to login with PingFedrate. So a button to login with PingFed appears(once a new SAML provider is configured in keycloak). On PingFedrate I tried to integrate SP inititated SSO:
I added a new SP connection and there I configured it as SSP initiated SSO. (It forced me to configure SOAP Authentication , where I selected basic and configured random username password). Then I downloaded metatdata.xml from this SP and imported in keycloak which autofilled the login url as : https://myserver:9031/idp/SSO.saml2 (i.e. without client id). After this when user clickon Login with PingFed - PingFed gives following error:
Unexpected System Error Sorry for the inconvenience. Please contact
your administrator for assistance and provide the reference number
below to help locate and correct the problem.
I found the solution to this.
Firstly, we need to add SP inititated SSO in Pingfed for keycloak.
Secondly, the reason I could not make SP inititated SSO work was that keycloak's entityId should be same as Pingfed SP connection's Partner's Entity Id / Connection Id.
Keycloak, by default keeps entity id equal to url of keyloak server containing your realm. E.g
https://(keycloak-server)/auth/realms/(realm-name)
(and I could not find a way to change it through Keycloak UI)
You need to enter this URL in Pingfed.
To avoid adding this manually, you can download the keycloak config from download export tab of identity provider.
And on Pingfed , import this file.
On a side note, though I was importing it earlier, I was changing value of Partenr id to some other name as I was not aware of above restriction until I started decoding the SAML tokens in request.
I have created a SAML 2.0 App on okta and have finished all the configurations. I then attempt to do an authorization from my application, by doing a redirect to the okta idp ->
http://www.okta.com/(okta created token)?SAMLRequest=(encoded saml xml)
The redirect returns a 404. When I go to my admin okta console I don't see any logs for the failed attempt, which i guess makes sense since it is returning a 404, but i don't know how to figure out what is causing the 404.
Is there a way to figure out what is causing the issue?
Install SAML tracer browser extensions and try it again to confirm the SAML Response is being decoded correctly.
To address your question "Is there a way to figure out what is causing the issue?", I have repeated your SAML 2.0 authentication steps suggested by your post.
The following responses and answer will help you to "figure out what is causing the issue".
(1) Quote your post "I have created a SAML 2.0 App on okta and have finished all the configurations. I then attempt to do an authorization from my application, by doing a redirect to the okta idp ->
http://www.okta.com/(okta created token)?SAMLRequest=(encoded saml xml)"
Response:
(I) I have created a SAML 2.0 SP App on okta and have finished all the configurations as you did.
(II) I then attempt to do an authorization from my SAML SP application, by doing a redirect to the okta idp as you did.
(III) Submit the username/password of local Okta user account (e.g., john.doe#example.com) to proceed with SAML authentication.
(2) Quote your post "The redirect returns a 404. When I go to my admin okta console I don't see any logs for the failed attempt, which i guess makes sense since it is returning a 404, but i don't know how to figure out what is causing the 404."
Response:
(I) In my experiment, the redirect returns the following error message instead of a 404 error.
Sorry, you can't access SAML 2.0 SP demo because you are not assigned this app in Okta.
If you're wondering why this is happening, please contact your administrator.
If it's any consolation, we can take you to your Okta home page.
(II) Then "I go to my admin okta console" as suggested by your post,
navigate to Reports > System Log, I saw the log below.
Event Info Targets
User attempted unauthorized access to app SAML 2.0 SP demo (AppInstance)
FAILURE :
(3) Quote your question "Is there a way to figure out what is causing the issue?"
Answer:
I summarize the four (4) potential root causes of your SAML authentication failure. The top #1 potential root cause is that you uploaded the wrong okta IdP metadata file into your SAML 2.0 SP app server (see the detailed description below).
(I) Potential Issue #1:
The root cause of my issue is that my local okta user account was NOT assigned to access this SAML 2.0 App.
Resolution:
(a) Navigate to Applications > SAML 2.0 App, then click Assign > Assign to People,
(b) On the pop-up dialog box, select the local Okta user accounts (e.g., John Doe (john.doe#example.com)), click Assign, click Save and Go Back, then click Done.
(c) Repeated the above SAML 2.0 authentication steps again, I was redirected back and logged in to SAML 2.0 App successfully.
(II) Potential Issue #2:
Three (3) potential root causes of this issue are that
(a) you did NOT fill in all the correct SAML SP information of your SAML 2.0 SP app on okta.
(b) or you did NOT upload the okta IdP metadata file into your SAML 2.0 SP app server
(c) or you uploaded the wrong okta IdP metadata file into your SAML 2.0 SP app server (this is the highest probability for bringing your 404 failure, because unlike most of SAML IdPs which create only one IdP metadata file for all SAML SP apps, okta create different IdP metadata files for different SAML SP apps).
Resolution:
Regarding to root cause (II.a): You need to ensure that the following SAML SP information should be the exactly the same as the SAML SP metadata of your SAML 2.0 SP app when you create new SAML 2.0 app.
Single sign on URL should come from your SAML SP metadata, e.g.,
<md:AssertionConsumerService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Location="https://your-saml-sp-app-URL/SAML2/POST" index="1"/>
Audience URI (SP Entity ID) should also come from your SAML SP metadata, e.g.,
<md:EntityDescriptor xmlns:md="urn:oasis:names:tc:SAML:2.0:metadata" ID="_random-string" entityID="https://your-saml-sp-app-URL/SAML2/Metadata">)
The sample SAML Settings of SAML 2.0 SP app on okta
Navigate to Applications > your SAML 2.0 App > general > SAML Settings
Single Sign On URL https://your-saml-sp-app-URL/SAML2/POST (i.e., your SAML SP AssertionConsumerService)
Recipient URL https://your-saml-sp-app-URL/SAML2/POST (i.e., your SAML SP AssertionConsumerService)
Destination URL https://your-saml-sp-app-URL/SAML2/POST (i.e., your SAML SP AssertionConsumerService)
Audience Restriction https://your-saml-sp-app-URL/SAML2/Metadata (i.e., your SAML SP entity ID)

SAML Single Logout Disabled
authnContextClassRef PasswordProtectedTransport
Honor Force Authentication Yes
SAML Issuer ID http://www.okta.com/${org.externalKey}
Regarding to root causes (II.b) and (II.c): You need to upload the correct okta IdP metadata into your SAML 2.0 SP app server.
Note that okta creates different okta IdP metadata files for your different SAML 2.0 SP apps.
Navigate to Applications > your SAML 2.0 App > Sign On
Identity Provider metadata is available if this application supports dynamic configuration.
Click Identity Provider metadata to download the okta IdP metadata for your SAML 2.0 SP app.
Log in to your SAML 2.0 SP app, upload the okta IdP metadata into your SAML 2.0 SP app, and then complete the configuration to store the okta IdP information on your SAML 2.0 SP app server.
Scenario:
1) Browser(User) requests resource from Service Provider (SP).
2) SP Redirects (with SAML Request) to Identity Provider (IdP).
3) Since it is first login, User gives the (IdP) his/her valid credentials.
4) IdP then redirects Browser (with SAML Response which includes SAML token) to the SP page.
After creation of user, If I try to authenticate it works as expected
but when I change user data on idp, and try after cleaning complete
browser data in any of browser (firefox, chrome) it shows only old
assertion data in SAML response on the way to idp to sp.
Even I have deleted user on idp and created again with same email id
with different user data it shows only old user data in SAML response.
There is nothing exist on browser side even cleaned cached data ,
cookies, and re-installed browser too.
I have gone through : Are SAML tokens cache/stored anywhere on the browser?
Not helped.
I there any settings on idp (OpenAM) side to resolve it? (I have unchecked Disable Federation persistence if NameID Format is unspecified:)
idp: OpenAM-12.0.0, sp: redmine SAML ominiauth
So what I miss here, I don't get it.
I got a solution by exploring the stuff at OpenAM side.
There is no issue with SAML plugin. It is OpenAM which cached SAML assertion attributes so every time it takes old assertion with SAML response.
To resolve issue need to follow below steps in OpenAM:
1) Select Federation-Select SP (from entity provider list)-Assertion content
-Check "Disable Federation persistence if NameID Format is unspecified:"
2) If above case won't work then follow this process:
-Select configuration-Servers and Sites-Default Server Settings:
-Add following properties:
-com.sun.identity.idm.cache.entry.expire.enabled=true
-com.sun.identity.idm.cache.entry.user.expire.time=10
-com.sun.identity.idm.cache.entry.default.expire.time=10
