# Libraries for LDAP user authentication

To use an LDAP directory service with Derby, you need these libraries in your classpath.

- jndi.jar

  JNDI classes

- ldap.jar

  LDAP provider from Sun

- providerutil.jar

  JNDI classes for a provider

Derby does not provide these libraries; they are available from Sun on the JNDI page. Use the 1.1.x versions of these libraries, not the 1.2.x versions. You might need to do two separate downloads to obtain all the required libraries.
