Flex-LDAP: Middleware LDAP baseado em palavra-chave

Abstract

In directories implementation is common the use of LDAP (Lightweight Directory Access Protocol) protocol. In these directories are stored objects that obey the LDAP schema. The queries effected on the directories use protocol specification, where the client effects queries with filters using parameters. In LDAP version 3 not possible queries without the knowledge of the LDAP schema. Our proposal is a LDAP system, named Flex-LDAP, that to be possible keywords-based queries. That LDAP system use Information Retri eval Model (vectorial model) to queries processing. To evaluate ours LDAP was implemented a server that running on two environments: the first with only LDAP server in version 3 and other with the Flex-LDAP between LDAP client and LDAP Server in version 3. The tests result shows better performance in throughput and flexible queries (only keywords in queries filter).
