| ## rdacl_get_referral(3sec) Gets a referral to an ACL update site Synopsis #include <dce/rdaclif.h void rdacl_get_referral( handle_t h, sec_acl_component_name_t component_name, uuid_t *manager_type, sec_acl_type_t sec_acl_type, sec_acl_tower_set_t *towers[ ], error_status_t *status); Parameters Input h A handle referring to the target object. component_name A character string containing the name of the target object. 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. sec_acl_type The ACL type. The sec_acl_type_t data type distinguishes the various types of ACLs an object can possess for a given manager type. The possible values are as follows: · sec_acl_type_object · sec_acl_type_default_object · sec_acl_type_default_container Output towers[ ] A pointer to address information indicating an ACL update site. This information, obtained from the RPC runtime, is used by the client-side code to construct a new ACL binding handle indicating a site that will not return the sec_acl_site_readonly error. The sec_acl_tower_set_t structure contains an array of towers (called towers[ ]) and an unsigned 32-bit integer indicating the number of array elements (called count). This type enables the client to pass in an unallocated array of towers and have the server allocate the correct amount. status A pointer to the completion status. On successful completion, the routine returns error_status_ok. Otherwise, it returns an error. Description The rdacl_get_referral( ) routine obtains a referral to an ACL update site. This function is used when the current ACL site yields a sec_acl_site_readonly error. Some replication managers will require all updates for a given object to be directed to a given replica. If clients of the generic ACL interface know they are dealing with an object that is replicated in this way, this function allows them to recover from the problem and rebind to the proper update site. The DCE network registry, for example, is replicated this way. Notes This call is not intended to be used by application programs. The sec_acl Application Programming Interface (API) provides all the functionality necessary to use the ACL facility. This reference page is provided for programmers who wish to write an ACL manager. In order to write an ACL manager, a programmer must implement the entire rdacl interface. This network interface is called on the client side via the sec_acl local interface. Developers are responsible for implementing the server side of this interface. Test server code is included as a sample implementation. Files /usr/include/dce/rdaclif.idl The idl file from which dce/rdaclif.h was derived. Errors The following describes a partial list of errors that might be returned. Refer to the OSF DCE Problem Determination Guide for complete descriptions of all error messages. sec_acl_unknown_manager_type The manager type selected is not an available option. error_status_ok The call was successful.
