Matching for ($dn) in the Target

The ($dn) macro in the target of an ACI determines the substitution value by comparing it to the entry targeted by the LDAP request. For example, you have an LDAP request targeted at this entry:

cn=all,ou=groups,dc=subdomain1, dc=hostedCompany1,dc=example,dc=com

In addition, you have an ACI that defines the target as follows:

(target="ldap:///ou=Groups,($dn),dc=example,dc=com")

The ($dn) macro matches with “dc=subdomain1, dc=hostedCompany1”. This substring is then used for substitutions in the subject of the ACI.
