The server software OpenLDAP integrates the IETF standard LDAP (Lightweight Directory Access Protocol) and serves as a reference system for other implementations that are based on this protocol. There are numerous commercial LDAP servers; however, with OpenLDAP an open source option is available, which you can apply free of license costs. Use one of the most effective LDAP implementations and benefit from the enormous flexibility which enables the application to adapt to the performance of the hardware. Overall, OpenLDAP adds stability to your IT infrastructure. If you need more or individual functionality, for example a work flow mechanism to write authorization attributes or to solve problems caused by data that is not standard compliant, DAASI International implements the desired functions for you using overlay programming.
