LDAP Command Examples

Following ldap command examples can be useful for Database Administrators, especially when working on the middletier.. I used these types of command to export/import the user information from Microsoft's Active Directory to Oracle 's Internet Directory.

*To Export all the user information (with all attributes) from a ldap directory

ldapsearch -p ldap_port -h  ldap_host -D "cn=adminuser" -w adminpasswd -L -s one -b "cn=Users,dc=company,dc=com" "(cn=*)" > users.ldif

*To Export all the user information (specifying attributes) from a ldap directory
ldapsearch -p ldap_port -h  ldap_host -D "cn=adminuser" -w adminpasswd -L -s one -b "cn=Users,dc=company,dc=com" "(cn=*)" attribute1 attribute2 attribute3 > users.ldif

*To Export a single user from an ldap directory (with all attributes)
ldapsearch -p ldap_port -h  ldap_host -D "cn=adminuser" -w admipasswd -L -s one -b "cn=Users,dc=company,dc=com" "(cn=user_you_want_to_export)"  > user.ldiff
