Directory Server enables you to use the host access control file hosts.allow and hosts.deny to specify the connection conditions to access the server. You can enable connection-based access control by using the dsconf command. Set the server property host-access-dir-path to the absolute path of the file system directory where the hosts.allow and hosts.deny files are located. See the server(5dsconf) and hosts_access(4) man pages for more information.
Connection-based access control can also be configured using ACIs. See ACI Bind Rules in Oracle Fusion Middleware Administration Guide for Oracle Directory Server Enterprise Edition for background on ACI bind rules.
