Enum SearchRequestDerefAliases

Source
#[non_exhaustive]
pub enum SearchRequestDerefAliases { NeverDerefAliases = 0, DerefInSearching = 1, DerefFindingBaseObj = 2, DerefAlways = 3, }
Expand description

An indicator as to whether or not alias entries are to be dereferenced during stages of the search operation.

The act of dereferencing an alias includes recursively dereferencing aliases that refer to aliases.

Servers must detect looping while dereferencing aliases in order to prevent denial-of-service attacks of this nature.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

NeverDerefAliases = 0

Do not dereference aliases in searching or in locating the base object of the search.

§

DerefInSearching = 1

While searching subordinates of the base object, dereference any alias within the search scope. Dereferenced objects become the vertices of further search scopes where the search operation is also applied.

If the search scope is SearchRequestScope::WholeSubtree, the search continues in the subtree(s) of any dereferenced object.

If the search scope is SearchRequestScope::SingleLevel, the search is applied to any dereferenced objects and is not applied to their subordinates.

Servers should eliminate duplicate entries that arise due to alias dereferencing while searching.

§

DerefFindingBaseObj = 2

Dereference aliases in locating the base object of the search, but not when searching subordinates of the base object.

§

DerefAlways = 3

Dereference aliases both in searching and in locating the base object of the search.
