Parameters

Input

callers_identity
A handle of type rpc_authz_cred_handle_t to the authenticated identity of the previous delegate in the delegation chain. The handle is supplied by the rpc_binding_inq_auth_caller( ) call.

delegation_type_permitted
A value of sec_id_delegation_type_t that specifies the type of delegation to be enabled. The types available are:

sec_id_deleg_type_none	No delegation.
sec_id_deleg_type_traced	Traced delegation.
sec_id_deleg_type_impersonation	Simple (impersonation) delegation.

The initiating client sets the type of delegation. If it is set as traced, all delegates must also specify traced delegation; they cannot specify simple delegation. The same is true if the initiating client sets the delegation type as simple; all subsequent delegates must also specify simple delegation. The intermediate delegates can, however, specify no delegation to indicate that the delegation chain can proceed no further.

delegate_restrictions
A pointer to a sec_id_restriction_set_t that supplies a list of servers that can act as delegates for the client becoming the delegate. These servers are added to the delegates permitted by the delegate_restrictions parameter of the sec_login_become_initiator call.

target_restrictions
A pointer to a sec_id_restriction_set_t that supplies a list of servers that can act as targets for the client becoming the delegate. These servers are added to targets specified by the target_restrictions parameter of the sec_login_become_initiator call.

optional_restrictions
A pointer to a sec_id_opt_req_t that supplies a list of application-defined optional restrictions that apply to the client becoming the delegate. These restrictions are added to the restrictions identified by the optional_restrictions parameter of the sec_login_become_initiator call.

required_restrictions
A pointer to a sec_id_opt_req_t that supplies a list of application-defined required restrictions that apply to the client becoming the delegate. These restrictions are added to the restrictions identified required_restrictions parameter of the sec_login_become_initiator call.

Output

status
A pointer to the completion status. On successful completion, status is assigned error_status_ok. Otherwise, it returns an error.

Description
The sec_login_become_impersonator( ) is used by intermediate servers to become a delegate for the client identified by callers_identity. The routine returns a new login context (of type sec_login_handle_t) that carries delegation information. This information includes the delegation type, delegate, and target restrictions, and any application-defined optional and required restrictions.

The new login context created by this call can then used to set up authenticated RPC with an intermediate or target server using the rpc_binding_set_auth_info( ) call.

The effective optional and required restrictions are the union of the optional and required restrictions specified in this call and specified by the initiating client and any intermediate clients. The effective target and delegate restrictions are the intersection of the target and delegate restrictions specified in this call and specified by the initiating client and any intermediate clients.

The sec_login_become_impersonator call is call is run only if the initiating client enabled simple delegation by setting the delegation_type_permitted parameter in the sec_login_become_initiator call to sec_id_deleg_type_simple.
