Oracle Fusion Middleware Administration Guide for Oracle Directory Server Enterprise Edition

Macro Matching for ($attr.attrName)

The ($attr.attrname) macro is always used in the subject part of a DN. For example, you could define the following roledn:

roledn = "ldap:///cn=DomainAdmins,($attr.ou),dc=HostedCompany1,dc=example,dc=com"

Now, assume that the server receives an LDAP operation that is targeted at the following entry:

dn: cn=Babs Jensen,ou=People,dc=HostedCompany1,dc=example,dc=com
cn: Babs Jensen
sn: Jensen
ou: Sales

To evaluate the roledn part of the ACI, the server reads the value of the ou attribute stored in the targeted entry. The server then substitutes this value in the subject to expand the macro. In the example, the roledn is expanded as follows:

roledn = "ldap:///cn=DomainAdmins,ou=Sales,dc=HostedCompany1,dc=example,dc=com"

Directory Server then evaluates the ACI according to the normal ACI evaluation algorithm.

When the attribute that is named in the macro is multivalued, each value is used in turn to expand the macro. The first value that provides a successful match is used.
