Sam Tunnicliffe commented on CASSANDRA-18018:
---------------------------------------------
The outcome of this, i.e. listing implicit rather than explicit perms of any
superuser, sounds fair enough, but the implementation is a little more
involved. The permissions are provided by the configured {{IAuthorizer}}
implementation, the impl that ships by default uses the system tables, but
there are others out there which do not.
The superuser status for a given role is inherited, meaning that to display the
permissions for any specific role, a lookup is required to check if any other
role (transitively) granted to it has superuser status. You can use
{{Roles::hasSuperuserStatus}} for this.
It's also possible to list permissions for all users, in which case we'll have
to group the permissions by grantee (they are simply ordered by grantee now)
and check the superuser status as we iterate the groups, either using them as
they are or replacing with the superuser perms.

> Project: Cassandra
> Issue Type: Bug
> Components: Feature/Authorization
> Reporter: Shailaja Koppu
> Priority: Normal
> Labels: lhf
>
> Running local Cassandra with below config:
> {noformat}
> authenticator: PasswordAuthenticator
> authorizer: CassandraAuthorizer
> role_manager: CassandraRoleManager
> network_authorizer: CassandraNetworkAuthorizer{noformat}
> Created a super user and then ran *Grant select* command on a keyspace.
> {noformat}
> shaadmin1@cqlsh> CREATE USER 'shaadmin1c1' WITH PASSWORD 'shaadmin1c1'
> SUPERUSER;
> shaadmin1@cqlsh:system_auth> grant select on testk1.t1 to shaadmin1c1;
> shaadmin1@cqlsh:system_auth> alter role shaadmin1c1 with access to all
> datacenters;
> {noformat}
>
> After this, list permissions command showing only select permission for that
> role on the resource.
> {noformat}
> shaadmin1c1@cqlsh> list all permissions of shaadmin1c1;
> role | username | resource | permission
> ----------------------------------------+-----------
> shaadmin1c1 | shaadmin1c1 | <table testk1.t1> | SELECT
> {noformat}
>
> Row in role_permissions table:
> {noformat}
> role | resource | permissions
> ------------------------------------------------------------------------------------------
> shaadmin1c1 | data/testk1/t1 | {'SELECT'}{noformat}
> But insert command by that role on the resource is successful because role is
> a super user
> {noformat}
> shaadmin1c1@cqlsh> insert into testk1.t1 (c1, c2) values ('a', 1);
> shaadmin1c1@cqlsh> select * from testk1.t1 ;
> c1 | c2
> ---+---
> a | 1
> (1 rows)
> {noformat}
>
> The problem is, output of list permissions command, which indicates only
> select permission on the resource, is misleading. I think list command need
> to be fixed to show all permissions super user has on the resource. Also
> grant command for a super user can be either a no-op or throw error, because
> the role already have requested permissions.
>
> Documentation also misleading:
> {quote}True automatically grants AUTHORIZE, CREATE and DROP permission on ALL
> ROLES.
> Superusers can only manage roles by default. To manage other resources,
> {color:#ff0000}you must grant the permission set to that resource. **
> {color}For example, to allow access management for all keyspaces: {{{}GRANT
> ALL PERMISSIONS ON ALL KEYSPACES TO }}\{{{}{*}role_name{*}{}}}.
> {quote}
