NAME

sec_login_become_initiator- Constructs a new login context that enables delegation for the calling client

SYNOPSIS

#include <dce/sec_login.h>

sec_login_handle_t sec_login_become_initiator (
    sec_login_handle_t my_login_context,
    sec_id_delegation_type_t delegation_type_permitted,
    sec_id_restriction_set_t *delegate_restrictions,
    sec_id_restriction_set_t *target_restrictions,
    sec_id_opt_req_t *optional_restrictions,
    sec_id_opt_req_t *required_restrictions,
    sec_id_compatibility_mode_t compatibility_mode,	
    error_status_t *status );

PARAMETERS

Input

my_login_context

A value of sec_login_handle_t that provides an opaque handle to the identity of the client that is enabling delegation. The sec_login_handle_t that specifies the client's identity is supplied as output of the following calls:

  • sec_login_get_current_context() if the client inherited the identity of the current context

  • The sec_login_setup_identity() and the sec_login_validate_identity() pair that together establish an authentiated identity if a new identity was established

delegation_type_permitted

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

sec_id_deleg_type_none

No delegation.

sec_id_deleg_type_traced

Traced delegation.

sec_id_deleg_type_impersonation

Simple (impersonation) delegation.

Note each subsequent intermediate delegate of the delegation chain started by the initiating client must set the delegation type to traced if the initiating client set it to traced or to simple if the initiating client set it to simple. Intermediate delegates, however, can set the delegation type to 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 initiating delegation.

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 initiating delegation.

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 initiating delegation.

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 initiating delegation.

compatibility_mode

A value of sec_id_compatibility_mode_t that specifies the compatibility mode to be used when the initiating client interacts with pre-1.1 servers. The modes available are as follows:

sec_id_compat_mode_none

Compatibility mode is off.

sec_id_compat_mode_initiator

Compatibility mode is on. The pre-1.1 PAC data is extracted from the EPAC of the initiating client.

sec_id_compat_mode_caller

Compatibility mode is on. The pre-1.1 PAC data extracted from the EPAC of the last client in the delegation chain.

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_initiator() enables delegation for the calling client by constructing a new login context (in a 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 is then used to to set up authenticated rpc with an intermediate server using the rpc_binding_set_auth_info() call. The intermediary can continue the delegation chain by calling sec_login_become_delegate() (if the delegation type is sec_id_deleg_type_traced) or sec_login_become_impersonator() (if the delegation type is sec_id_deleg_type_impersonation).
