What I actually want to do is to restrict the application listing on
the account page to just the clients where a user has a role mapping.
Currently this is only possible via "Full Scope Allowed -> off" 
and explicit role mappings.
Then an admin has full control over what applications a user can see in the listing.

What I now ended up with is modifying the application.ftl in a custom theme 
that explicitly excludes clients with no role mappings for the current user
(+ the account client itself).

<#list applications.applications as application>
        <#-- filters out "account" app & anything that the user doesn't have an explicitly defined role in. -->
        <#if application.client.clientId != 'account' && application.resourceRolesAvailable[application.client.clientId]?has_content>
     
     //render account 

        </#if>
</#list>


Here are some of my experiments that describe the default behaviour of the 
"Full Scope Allowed" Setting in combination with the application listing in the account page.

Scenario 1)

client      role            Full Scope Allowed
client-a    "user-role-a"   "on"
client-b    "user-role-b"   "on"

user    roles
user-a  client-a: user-role-a
user-b  client-b: user-role-b

On account/applications page

user    applications with access
user-a  account (full access), client-a (full access), client-b (full access)
user-b  account (full access), client-a (full access), client-b (full access)

---

Scenario 2)

client      role            Full Scope Allowed
client-a    "user-role-a"   "off"
client-b    "user-role-a"   "on"

user    roles
user-a  client-a: user-role-a
user-b  client-b: user-role-b

On account/applications page

user    applications with access
user-a  account (full access), client-a (full access), client-b (full access)
user-b  account (full access), client-b (full access)

---

Scenario 3)

client      role            Full Scope Allowed
client-a    "user-role-a"   "on"
client-b    "user-role-b"   "off"

user    roles
user-a  client-a: user-role-a
user-b  client-b: user-role-b

On account/applications page

user    applications with access
user-a  account (full access), client-a (full access)
user-b  account (full access), client-a (full access), client-b (full access)

-> user-a sees only the application he has acces to
-> user-b sees however also sees client-a although he doesn't have a role mapping for client-a

---

Scenario 4)

client      role            Full Scope Allowed
client-a    "user-role-a"   "off"
client-b    "user-role-b"   "off"

user    roles
user-a  client-a: user-role-a
user-b  client-b: user-role-b

On account/applications page

user    applications with access
user-a  account (full access), client-a (full access)
user-b  account (full access), client-b (full access)

-> User only sees the applications for which he has roles
---

Scenario 5) introduced a common client...

client      role            Full Scope Allowed
client-a    "user-role-a"   "off"
client-b    "user-role-b"   "off"
client-c    "user-role-c"   "on"

user    roles
user-a  client-a: user-role-a, client-c: user-role-c
user-b  client-b: user-role-b

On account/applications page

user    applications with access
user-a  account (full access), client-a (full access), client-c (full access)
user-b  account (full access), client-b (full access), client-c (full access)

-> user-a sees only the applications he has a role for or access to: client-a, client-c
-> user-a sees client-c for which he doesn't have a role mapping

Steps to reproduce:

create client A with client id "client-a" with a newly defined role "user"
create client B with client id "client-b" with a newly defined role "user"

create user A with username "user-a" with "user" role granted for "client-a"
create user B with username "user-b" with "user" role granted for "client-b"

Goto applications tab in account page:
http://localhost:8082/auth/realms/eurodata.local/account/applications

login as user-a

Actual: The listing shows both applications client-a AND client-b 
        although the user-a only has a user-role to client-a.
Expected: Only client-a (+ account) applications should be shown
 So "client-a" and "client-b" have fullScopeAllowed on? If yes, then the current behaviour is correct IMO. The thing is that user-a is able to login to application "client-b" and retrieve the accessToken for "client-b". And this accessToken will contain "user" role to "client-a" because of fullScopeAllowed.


The scope is used to limit the roles, which will user see after retrieve accessToken for particular client. So for example if you limit scope to client-a, then accessToken for user-a to client-b won't contain "user" role of "client-a". But if you retrieve accessToken for client-a, it will contain it.

Since the user-a doesn't have role "user" for "client-b" you will never see this role in any access token. So current behaviour is correct to me.

logout

login as user-b

By default a client has the "Full Scope Allowed" switch set to "on".
Changing this switch to "off" and explicitly assigning the client role "user" to "client-a" 
in the scope settings for client-a and to the user role for client-b in the scope settings 
for client-b solves the issue.

With this setting only the applications for which a user actually has the "user" role is shown.

Even though the help text for "Full Scope Allowed" says: "Allows you to disable all restrictions"
one would expect that "Full Scope Allowed" set to "on" would honor the assigned roles.

Is there something wrong here or should the help text be more descriptive?
I think the piece of code that does this is: org.keycloak.protocol.oidc.TokenManager.getAccess(String, boolean, ClientModel, UserModel)

Thomas
