Creating Smart Referrals from the Command Line

Use the ldapmodify command-line utility[2] to create smart referrals from the command line.
To create a smart referral, create the relevant directory entry, and add the referral object class. This object class allows a single attribute, ref. The ref attribute must contain an LDAP URL.
For example, add the following to return a smart referral for an existing entry, uid=jdoe:
dn: uid=jdoe,ou=people,dc=example,dc=com 
objectclass: referral
ref: ldap://directory.europe.example.com/cn=john%20doe,ou=people,l=europe,dc=example,dc=com


Any information after a space in an LDAP URL is ignored by the server. For this reason, use %20 instead of spaces in any LDAP URL used as a referral.
To add the entry uid=jdoe,ou=people,dc=example,dc=com with a referral to directory.europe.example.com, include the following in the LDIF file before importing:
dn: uid=jdoe, ou=people,dc=example,dc=com 
objectclass: top
objectclass: person
objectclass: organizationalperson
objectclass: inetOrgPerson
objectclass: referral
cn: john doe
sn: doe
uid: jdoe
ref: ldap://directory.europe.example.com/cn=john%20doe,ou=people, l=europe,dc=example,dc=com
Use the -M option with ldapmodify when there is already a referral in the DN path. For information about the ldapmodify utility, see the Directory Server Configuration, Command, and File Reference.
