NAME
sec_acl_test_access_on_behalf - Tests access to an object on behalf of
another process
SYNOPSIS
#include <dce/daclif.h>
boolean32 sec_acl_test_access_on_behalf(
sec_acl_handle_t h,
uuid_t *manager_type,
sec_id_pac_t *subject,
sec_acl_permset_t desired_permset,
error_status_t *status);
PARAMETERS
Input
h A handle referring to the target object. Use sec_acl_bind() to
create this handle.
manager_type
A pointer to the UUID identifying the type of the ACL manager
in question. There may be more than one type of ACL manager
protecting the object whose ACL is bound to the input handle.
Use this parameter to distinguish them. Use
sec_acl_get_manager_types() to acquire a list of the manager
types protecting a given object.
subject
A Privilege Attribute Certificate (PAC) for the subject process.
The PAC contains the name and UUID of the principal and cell of
the subject process, as well as a list of any groups to which it
belongs. The PAC also contains a flag (named authenticated).
When set, it indicates that the certificate was obtained from an
authenticated source. When not set, the certificate must not be
trusted. (The field is FALSE when it was obtained from the
rpc_auth layer and the protect level was set to
rpc_c_protect_level_none. This indicates that no authentication
protocol was actually used in the remote procedure call; the
identity was simply transmitted from the caller to the callee.
If an authentication protocol was used, then the flag is set to
TRUE.) If a null PAC is passed, the subject is treated as an
"anonymous user", matching only the any_other and unauthenticated
entries (if they exist) on the ACL. A server uses
rpc_binding_inq_auth_client() to acquire a certificate for the
client process.
desired_permset
A permission set in sec_acl_permset_t form containing the desired
privileges. This is a 32-bit set of permission flags supported by
the manager type.
Output
status
A pointer to the completion status. On successful completion,
the routine returns error_status_ok. Otherwise, it returns an
error.
DESCRIPTION
The sec_acl_test_access_on_behalf() routine determines if the specified
ACL contains entries that grant the privileges specified in
desired_permset to the subject process. An application generally
inquires about only the minimum set of privileges needed to accomplish
a specific task.
Permissions Required
The sec_acl_test_access_on_behalf() routine requires at least one
permission of any kind on the object for which the privileges are to
be tested. Both the calling process and the identified subject must
have permission on the object.
FILES
SYS$COMMON:[DCE$LIBRARY]DACLIF.IDL
The idl file from which dce/daclif.h was derived.
RETURN VALUES
If the routine completes successfully (with a completion status of
error_status_ok) it returns a value of
+ TRUE if the caller has any access (at least one permission of any
kind), and the subject has the desired_permset privileges.
+ FALSE if both the caller and the subject have any access, but the
subject does not have the desired_permset privileges.
If the routine does not complete successfully, it returns a bad
completion status code and a return value of FALSE.
ERRORS
sec_acl_unknown_manager_type
The manager type selected is not an available option.
error_status_ok
The call was successful.
