For some reason, User A can view all of the posts but can only edit posts published by non-admins.  User A can only view admin post, not edit or delte them.  The only way I have been able to permit User A to edit admin posts is by elevating User A to an admin.

Something like this has been reported occasionally, and I've never been able to reproduce it. I'll try later this afternoon, but may need ftp access to your role-scoper folder and a sample login to track it down.

This turns out to be a conflict with the Exec-PHP plugin. It's documented in RoleScoper_PluginCompat.html (installed in plugin folder); I had just forgotten the symptoms. I'm making a mental note to publish such plugin compatibility issues more prominently.

With the login you provided, I took the liberty of editing your Exec-PHP (as described below) to eliminate the conflict .

Exec-PHP:

Recursive has_cap call in Exec-PHP seems to cause problems for other has_cap filters.

Must modify includes/runtime.php as follows:

change:

if (!$poster->has_cap(ExecPhp_CAPABILITY_EXECUTE_ARTICLES))

to:

$exec_articles_cap = ExecPhp_CAPABILITY_EXECUTE_ARTICLES;
if ( empty($poster->allcaps[$exec_articles_cap]) )

I am having this same problem, and I did what you said to the Exec-Php file, but it did not solve my problem. What should I do?

I have PHP EXECUTION plugin installed and am having the same problem where users see the page that they have permission to edit in their page list, but when they click on the page, they get the "you don't have permission to edit this page"

Any ideas?

I found that both plugins were contributing to this conflict. The Role Scoper issue (capability requirements applied by other plugins is not reflected in edit link in Edit Posts listing) is now fixed in Role Scoper 1.2.9.RC6 and 1.3.RC6.

The PHP Execution issue and workaround:

As of PHP Execution v1.0.0, the mechanism to limit editing based on post author capabilities is inherently incompatible w/ Role Scoper. Edit php-execution-plugin/includes/class.php_execution.php as follows :

change:

    add_filter('user_has_cap', array(&$this,'action_user_has_cap'),10,3);

to:

    add_filter( 'map_meta_cap', array( &$this,'map_meta_cap' ), 10, 4 );

replace function action_user_has_cap with :

    function map_meta_cap( $caps, $meta_cap, $user_id, $args ) {
        $object_id = ( is_array($args) ) ? $args[0] : $args;
        if ( ! $post = get_post( $object_id ) )
            return $caps;

        if ( function_exists( 'get_post_type_object' ) ) {
            $type_obj = get_post_type_object( $post->post_type );
            $is_edit_cap = ( ( $type_obj->cap->edit_post == $meta_cap ) && in_array( $type_obj->cap->edit_others_posts, $caps ) );
        } else {
            $is_edit_cap = in_array( $meta_cap, array( 'edit_post', 'edit_page' ) ) && array_intersect( $caps, array( 'edit_others_posts', 'edit_others_pages' ) );
        }

        if ( $is_edit_cap ) {
            $id = $post->post_author;

            if ( isset( $this->cap_cache[$id] ) ) {
                $author_can_exec_php = $this->cap_cache[$id];
            } else {
                $author = new WP_User($id);
                $author_can_exec_php = ! empty( $author->allcaps[PHP_EXECUTION_CAPABILITY] );
                $this->cap_cache[$id] = $author_can_exec_php;
            }

            if ( $author_can_exec_php ) 
                $caps []= PHP_EXECUTION_CAPABILITY;
        }

        return $caps;	
    }
