You should be able to obtain any attribute defined to the user.
But regarding group attributes from the resource instance, it won't work
because this functionality is not exposing group's attributes via the
resource instance.
There are other things we need to improve in this functionality of
fine-grained permissions to admin console. There are a few things missing
or too complicated to be done ...

Hello
I am trying to write a javascript Attribute Based Access Control (ABAC)
policy.
I want to control the access to group resource using the authenticated
user's attributes and the attributes configured on the group.
So I configured the policy via Groups > myGroup > permissions >
view-members and select my javascript policy.
Problem: in the script, neither my identity nor my group attributes are
available.
Here is my script:
var context = $evaluation.getContext();
var resourcePermission = $evaluation.getPermission();
var identity = context.getIdentity();
var idAttributes = identity.getAttributes();
var ctxAttributes = context.getAttributes();
var resource = resourcePermission.getResource();
print('idAttributes.CUSTOM_PROP: ' + idAttributes.getValue('CUSTOM_
PROP'));
print('ctxAttributes.CUSTOM_PROP: ' + ctxAttributes.getValue('
CUSTOM_PROP'));
print('resource.getAttributes: ' + resource.getAttributes);
$evaluation.grant();
When I use the API end point as follow :
http://keycloak.dev.local/auth/admin/realms/ngp/groups/myGroup/members/
It triggers the script and prints the following in wildfly console :
ESC[0mESC[0m15:36:13,000 INFO [stdout] (default task-3)
idAttributes.CUSTOM_PROP: null
ESC[0mESC[0m15:36:13,011 INFO [stdout] (default task-3)
ctxAttributes.CUSTOM_PROP: null
ESC[0mESC[0m15:36:13,011 INFO [stdout] (default task-3)
resource.getAttributes: undefined
So my custom attribute is null. And worse, the resource does not even
seems to have a getAttributes() method at all ?!
I tripple checked, my user has the custom attribute "CUSTOM_PROP" defined
with value "test" and my group has attributes as well.
The documentation says the resource I retrieve that way should be an
instance of org.keycloak.authorization.model.Resource
which, according to the javadoc, must define a getAttributes() methods.
However it's ... undefined ?!
The keycloak version I use is 4.0.0.
Can anyone help me find what's wrong with my script ?
Many thanks,
Nicolas GILLET
