Overview #

The UsedBy attribute contains the Distributed Reference Links for NDS External References.

Distributed Reference Links manage references throughout the NDS tree and are automatically maintained by NDS. These links identify a Partition Root Entry, and that specified partition contains an object that references the object with the UsedBy attribute. [1]

Example UsedBy Value #

In LDAP, an example value might be like:

ou=apps,ou=esc,dc=willeke,dc=com#0# 

Numeric OID: 2.16.840.1.113719.1.1.4.1.186 #

Attribute Names: UsedBy #

Syntax: 2.16.840.1.113719.1.1.5.1.15 Tagged Name and String #

• UPPERBOUND: 64512

The Path syntax, in for the UsedBy contains three uint32 fields and a data field. The UsedBy attribute uses only the first two fields. The first field identifies whether the attribute points to a partition. The second field is the partition root ID.[1]

For LDAP clients to access this attribute, the LDAP server must be configured to map the attribute to a name without spaces or colons. The LDAP server in NDS eDirectory supports the Path syntax.
