Overview#

An attribute value assertion (AVA) is a combination of an attribute description and an Attribute Value.

The Assertion Value is used in conjunction with a matchingRule in order to make the determination. If the matching rule is an equality matching rule, then it will be used to determine whether the attribute contains a given value.

If it is an ordering matching rule, then the Attribute Value Assertion will be used to determine whether the attribute contains a value that is greater than or equal to, or less than or equal to, the assertion value.

If it is an approximate matching rule, then the Attribute Value Assertion will be used to determine whether the attribute contains a value that is approximately equal to the assertion value.

Substring matching is more complex and uses a Substring Assertion rather than a simple Attribute Value Assertion.

Attribute Value Assertion are used in Compare Request, as well as Equality SearchFilter, Greater-Or-Equal SearchFilter, LessThan-Or-Equal SearchFilter, and approximate match LDAP SearchFilters.
