Abstract
A method of hierarchical LDAP searching in an LDAP directory service having a relational database management system (DBMS) as a backing store. The method begins by parsing an LDAP filter-based query for elements and logical operators of the filter query. For each filter element, the method generates an SQL subquery according to a set of translation rules. For each SQL subquery, the method then generates a set of entry identifiers for the LDAP filter query. Then, the SQL subqueries are combined into a single SQL query according to a set of combination rules chosen corresponding to the logical operators of the LDAP filter query.
