LDAP Commands
Server Training - Server Management

There are several basic commands to run LDAP. Each of these commands is installed in the /usr/sbin directory and must be run as root.

Lesson 2 / Lesson 4

Important: The slap commands need to be run when the directory is off, so be sure to shut down LDAP before you run those commands.  If you want to use commands while the directory is online use the ldap commands.

slapd - this is the LDAP server daemon

slurpd - the daemon that synchronizes with other LDAP servers

slapadd - this program is used to add ldif files into LDAP

# slapadd -l users.ldif

slappasswd - it will create a password that can be used with ldapmodify, or rootpw.   You have to copy and paste the password into your file.

# slappasswd
New password:
Re-enter new password:

slapcat – retrieves entries from LDAP directory
slapindex – reindexes the slapd directory

ldapadd – adds entries to LDAP

ldapadd -x -D "cn=admin,dc=linux,dc=local" -W -f users.ldif

ldapdelete – deletes entries
ldapmodify – modifies LDAP entries
The "-W" is an option that will request your password.

 ldapmodify -D "cn=admin,dc=linux,dc=local" -W -x -v -f /etc/openldap/users.ldif

ldapsearch – search for entries
This example will search for all entries.

# ldapsearch -x -b "dc=linux,dc=local" "(objectclass=*)"

ldapcompare – create comparison parameters
ldapwhoami – run whoami
ldapmodrdn – modifies RDN entries
