You should be able to obtain the context instance like that [1]. And then,
invoke the method to programmatically enforce access.
If I understand correctly, the permission map you pass is basically the set
of resource/scopes that you want to return in a permission ticket and later
on check if the resulting RPT is granted with the same set. We should
ideally reuse as much as possible the main logic in the enforcer. And the
enforcement mode should be permissive or disabled to allow the request to
reach your endpoint so you can enforce access by yourself.
In any case, the PE should allow the request to pass with an empty
authorization context so that you can invoke the appropriate method to
enforce access.

Just by looking , changes look good .
I have a question , how will I invoke it programatically , I mean on what
object i have to call , giving permission (Map) as as an input parameter.
If I specify enforcement mode as Enforcing or Permissive , permission will
always be null
Also it will be good if we can incorporate audit logging , if not now then
we can consider it in future

I see. I'm just trying to figure out if we can't somehow address the
problem by enhancing the configuration. For instance, in regards to the
`/api/datasets/{databasename}` I think we have a similar approach in the
Photoz quickstart, where the path parameter representing the ID of the
resource is used to automatically create the ticket and enforce access
later on when an RPT arrives.
But yeah, the other scenarios are not covered.
I'm OK to improve this based on your changes and following an approach
similar to what I shared from my branch. Does it make sense for you ? I may
have removed some bits from your original changes but the idea is just to
show how we could leverage the `AuthorizationContext`, which is already
available to the application through `KeycloakSecurityContext`.

I want to clarify little bit about the example you are stating ,
{
"path" : "/someUri/*",
"methods" : [
{
"method": "GET",
"scopes" : ["view"]
},
{
"method": "DELETE",
"scopes" : ["delete"]
}
]
},
See , if our resources are static and not dynamic , I can put them in a
keycloak.json file no worries.
But when it comes to resources which are not end-point specific or not
directly related to endpoint , but the actual data itself. I think it is
better to keep them on server side rather than a config file . It can be
1000 at present , it can be lakhs and crores if i consider the future scope
for eg-: /api/datasets/{datasetname} , each dataset will be resource and
we will be configuring resources as /datasets/dataset1
/datasets/dataset2
So, each dataset will be a resource and will be created in keycloak server
when the actual Data is created. So , every time i create a resource , i
won't require to configure keycloak.json.
The current implementation of configuring paths that keycloak provides is
good when resources are static. for eg-: if end points are resources , so
they are most likely static . But for our case it won't work
Another example can be , if there is a non rest resource and scope /
action is coming as a query parameter. Current keycloak implementation will
not work as we can configure only on URL's . So the customEnforcer will
provide the flexibility to cover all these cases.
There are other cases , where there is a pipeline which is dependent on
another resources.
So let's consider Non Rest resource such as PIPELINE , A pipeline itself
will contain a set of resources , So Pipeline can have a scope START, STOP
, DELETE , RESTART etc.
So resources and actions can come as a query parameter . So , the
custom-enforcer functionality can provide us enforcing policies with use
cases like that
Hope the use case is getting more clearer to you
Thanks

Here is a scratch [1]. But I'm not fully convinced about the changes you
are proposing. Maybe what is missing is an example of how this will be used
in practice.
Isn't that the same thing as configuring a path like this?
```
{
"path" : "/someUri/*",
"methods" : [
{
"method": "GET",
"scopes" : ["view"]
},
{
"method": "DELETE",
"scopes" : ["delete"]
}
]
},
```

Can you suggest pseudo flow what you are trying to say
It will be good for me to understand how it can be achieved using
AuthorizationContext .

*Subject:* Custom Policy Enforcer
Hi,
We have started some discussions about a custom policy enforcer at
https://github.com/keycloak/keycloak/pull/6448.
For those interested in how to programmatically enforce permissions,
please look at that PR and discussions that should start to happen here.
@Sushil Singh <sushil.singh(a)guavus.com>, If the idea is to expose the PE
functionality so that you can programmatically get the same behavior to
when requests are processed, I think we can still make it through the
`AuthorizationContex` interface.
In fact, the code won't change much from what you did so we basically
encapsulate the call to the actual policy enforcer.
Regards.
Pedro Igor
