Lightweight Directory Access Protocol (LDAP) directories have recently proliferated with the growth of distributed computing. They are being used in a variety of network based applications to store information about not only people and organizations but also network resources and policies. Given the diversity of its applications and its frequent use in conjunction with transaction aware applications (databases, application servers), there is a great demand for LDAP servers to support transactions. In this paper we focus on LDAP servers using a relational database to store the data. We propose a nested transaction model for implementing LDAP transactions. The proposed model not only simplifies the LDAP to SQL translation but also imposes minimum requirements on the underlying relational database platform. We also present a locking based concurrency control protocol and recovery mechanism for LDAP transactions.
