Lightweight Directory Access Protocol (LDAP) is used to access centrally stored information over a network. LDAP servers store information in a database called a directory, which is optimized for searches. Directory entries are arranged in a hierarchical tree-like structure. This directory can store a variety of information such as names, addresses, phone numbers, network services, printers, and other types of data. LDAP can also be used to authenticate users, allowing users to access their accounts from any machine on the LDAP network.
RedHat Linux includes OpenLDAP, which is an open source implementation of the LDAP protocols. Below is a list of OpenLDAP Server and Client Utilities list and their respective functions.
OpenLDPA server Utilities
The openldap-servers package also includes the following utilities:
slapacl: Checks the access to a list of attributes
slapadd: Adds entries from an LDIF file to an LDAP directory
slapauth: Checks a list of IDs for authentication and authorization permissions
slapcat: Generates LDIF output from an LDAP directory
slapdn: Checks a list of distinguished names (DNs) based on schema syntax
slapindex: Re-indexes the directory. Run slapindex whenever indexing options are changed in the configuration file.
slappasswd: Is a password utility for creating an encrypted user password
slapschema: Checks compliance of a database with the corresponding schema
slaptest: Checks the LDAP server configuration
OpenLDAP Client Utilities
The openldap-clients package installs the following utilities:
ldapadd: Adds entries to an LDAP directory either from a file or from standard input. ldapadd is a symbolic link to ldapmodify -a.
ldapmodify: Modifies entries in an LDAP directory
ldapcompare: Compares a given attribute with an LDAP directory entry
ldapdelete: Deletes entries from an LDAP directory
ldapexop: Performs extended LDAP operations
ldapmodrdn: Modifies the RDN value of an LDAP directory entry
ldappasswd: Is a password utility for an LDAP user
ldapsearch: Is an LDAP directory search tool
ldapurl: Is an LDAP URL formatting tool

There are several LDAP client software applications that provide a graphical user interface (GUI) for maintaining LDAP directories.
