The iControl architecture is open and uses standard schemas, allowing integration with existing security infrastructures. iControl supports integration with existing directory services using standard schemas for authentication. The system can be configured to use an external LDAP server or directory services server instead of using the iControl LDAP server.

It is also possible to use multiple LDAP servers with referral capabilities. For example, iControl can bind and authenticate with an external LDAP server, but manage its permissions on the iControl LDAP server for iControl-specific resources. Referrals are supported between LDAP databases to support multiple domain authentication.

In the case where it is not possible to get direct access to directory services, iControl can be integrated with an existing enterprise “single sign-on” system. For example, iControl interfaces with Netegrity SiteMinder from Computer Associates to authenticate users.
