Definition: Equality Search Filter
An equality search filter is a type of search filter that can be used to identify entries that contain a specific value for a given attribute. The server will use an equality matching rule to make the determination.
The string representation of an LDAP equality filter is comprised of an opening parenthesis followed by the attribute name, an equal sign, the attribute value, and the closing parenthesis. For example, an equality filter of "(uid=john.doe)" will match any entry in which the uid attribute contains a value of "john.doe".
