sec_rgy_attr_get_effective(3sec)

Reads effective attributes by ID

Synopsis

#include <dce/sec_rgy_attr.h>

void sec_rgy_attr_get_effective(
sec_rgy_handle_t context,
sec_rgy_domain_t name_domain,
sec_rgy_name_t name,
unsigned32 num_attr_keys,
sec_attr_t attr_keys[ ],
sec_attr_vec_t *attr_list,
error_status_t status);

Parameters

Input

context
An opaque handle bound to a registry server. Use sec_rgy_site_open( ) to acquire a bound handle.

name_domain
A value of type sec_rgy_domain_t that identifies the domain in which the named object resides. The valid values are as follows:

sec_rgy_domain_principal
The name identifies a principal.

sec_rgy_domain_group
The name identifies a group.

sec_rgy_domain_org
The name identifies an organization.

This parameter is ignored if name is policy or replist.

name
A pointer to a sec_rgy_name_t character string containing the name of the person, group, or organization to which the attribute is attached.

num_attr_keys
An unsigned 32-bit integer that specifies the number of elements in the attr_keys[ ] array. If num_attr_keys is set to 0, all of the effective attributes that the caller is authorized to see are returned.

attr_keys[ ]
An array of values of type sec_attr_t that specify the UUIDs of the attributes to be returned if they are effective. If the attribute type is associated with a query attribute trigger, the sec_attr_t attr_value field can be used to pass in optional information required by the attribute trigger query. If no information is to be passed in the attr_value field (whether the type indicates an attribute trigger query or not), set the attribute's encoding type to sec_rgy_attr_enc_void. The size of the attr_keys[ ] array is determined by the num_attr_keys parameter.

Output

attr_list
A pointer an attribute vector allocated by the server containing all of the effective attributes matching the search criteria (defined in num_attr_keys or attr_keys[ ] ). The server allocates a buffer large enough to return all the requested attributes so that subsequent calls are not necessary.

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

Description
The sec_rgy_attr_get_effective( ) routine returns the UUIDs of a specified object's effective attributes. Effective attributes are determined by setting of the schema entry apply_defaults flag:

· If the flag is set off, only the attributes directly attached to the object are effective.

· If the flag is set on, the effective attributes are obtained by performing the following steps for each attribute identified by UUID in the attr_keys[ ] array:

1. If the object named by name is a principal and if the a requested attribute exists on the principal, that attribute is effective and is returned. If it does not exist, the search continues.

2. The next step in the search depends on the type of object:

For principals with accounts:
a. The organization named in the principal's account is examined to see if an attribute of the requested type exists. If it does, it is effective and is returned; then the search for that attribute ends. If it does not exist, the search for that attribute continues to the policy object as described in b, below.

b. The registry policy object is examined to see if an attribute of the requested type exits. If it does, it is returned. If it does not, a message indicating the no attribute of the type exists for the object is returned.

For principals without accounts, for groups, and for organizations:
The registry policy object is examined to see if an attribute of the requested type exits. If it does, it is returned. If it does not, a message indicating the no attribute of the type exists for the object is returned.

For multivalued attributes, the call returns a sec_attr_t for each value as an individual attribute instance. For attribute sets, the call returns a sec_attr_t for each member of the set; it does not return the set instance.

If the attribute instance to be read is associated with a query attribute trigger that requires additional information before it can process the query request, use a sec_attr_value_t to supply the requested information. To do this:

· Set the sec_attr_encoding_t to an encoding type that is compatible with the information required by the query attribute trigger.

· Set the sec_attr_value_t to hold the required information.

If the attribute instance to be read is not associated with a query trigger or no additional information is required by the query trigger, an attribute UUID is all that is required. For these attribute instances, supply the attribute UUID in the input array and set the attribute encoding (in sec_attr_encoding_t) to sec_attr_enc_void.

If the requested attribute type is associated with a query trigger, the value returned for the attribute will be the binding (as set in the schema entry) of the trigger server. The caller must bind to the trigger server and pass the original input query attribute to the sec_attr_trig_query call in order to retrieve the attribute value.
