A directory server is a type of network daemon that stores data in a manner accessible to external clients. Directory servers typically use LDAP or DSML for communicating with clients, although some servers use other protocols like DAP or NDS.
Directory servers store data in a hierarchical form (called the directory information tree) and provide the ability for clients to interact with that information, including:
search operations, which make it possible to find all entry matching a given set of criteria
add operations, which make it possible to add new entries to the server
delete operations, which make it possible to remove entries from the server
modify operations, which make it possible to update existing information in the server
modify DN operations, which make it possible to rename entries in the server
bind operations, which make it possible to authenticate users to the server
compare operations, which make it possible to determine whether entries have a particular attribute-value pair
The directory server uses LDAPv3 for communicating with network clients, and provides a DSML gateway that can be used to handle DSML requests.
