Ident_ADS_Realtime

Sample workflow to provision an Active Directory domain from a DirX Identity target system.

A provisioning workflow transfers the account, group and membership changes that DirX Identity has calculated for a target system into the connected system, and acknowledges the result back into the Identity Store. It is the workflow that executes what privilege resolution has decided: when a user gains or loses a privilege, the resolution writes the resulting account or membership change into the target system subtree of the Identity Store, and this workflow applies that change to the connected system.

The workflow processes single requests as they arrive, so it reflects changes with little delay. Use the corresponding validation workflow to detect changes that were made in the connected system outside of DirX Identity.

Ident_ADS_Realtime is the provisioning workflow for connected systems of type ADS. It keeps an Active Directory domain in step with the target system subtree that represents that domain in the Identity Store. Because the ADS connector reaches the domain through native LDAP, the same workflow also carries the Exchange and Skype for Business attributes that DirX Identity maintains on an Active Directory account.

The tsresource and tscluster parameters declare that a target system of this type represents a domain and that several domains form a forest, which is how the Identity Store models an Active Directory installation.

The workflows in this reference are delivered as factory data and are loaded into the Connectivity configuration database during the initial configuration. They are samples: use the Identity Manager to copy a workflow into your own scenario and adapt the copy. Do not change the delivered objects, because a product update can replace them.

Prerequisites

  • A connected directory of type ADS that points to an Active Directory domain controller, with the bind profile ADSadmin set to an account that may create, modify and delete user objects and groups in the target containers.

  • SSL is switched on for the TS port, so the domain controller must offer LDAPS and its certificate must be trusted by the Java-based Server.

  • A target system of type ADS in the Identity Store that is linked to that connected directory, and a completed initial load, so that the target system subtree reflects the current content of the domain.

  • The Java-based Server that runs the workflow must be able to reach both the domain controller and the Identity Store; the Identity Store is accessed through the bind profile Domain_Admin.

A Java-based real-time workflow runs as a permanently loaded configuration in the Java-based Server (IdS-J). It is triggered by a request or an event rather than by a schedule. Each workflow consists of activities; an activity opens one port per system it talks to, and each port uses a connector to reach that system.

Most provisioning workflows contain a join activity that performs the actual work and an error activity that receives requests which still fail after all retries and sends a notification about them. The retrylimit, waitbeforeretry and timeout parameters of an activity control how often and how long a failed request is retried before it is handed to the error activity.

The event port publishes change events over JMS, and the notify port sends e-mail notifications. Neither port is bound to a connected directory.

The join activity does the provisioning work. Its IdentityDomain port reads the requested state from the Identity Store over the accounts, groups and members channels, and its TS port writes that state into the Active Directory domain over the channels of the same name. The additional setPassword channel of the TS port lets the workflow write the password attribute unicodePwd together with a new account. The CryptFilter on the TS port decrypts the password before it is handed to the connector.

A request that fails is retried up to five times (retrylimit) with 90 minutes between the attempts (waitbeforeretry). If it still fails, the error activity takes it over and sends a notification through the Message port; the workflow parameter timeout gives a request four days before it is discarded.

Operation

  1. Privilege resolution writes an account, group or membership change into the ADS target system subtree of the Identity Store and marks it for provisioning.

  2. The Java-based Server passes the resulting request to the join activity of this workflow.

  3. The IdentityDomain port reads the affected entry from the Identity Store over the matching channel.

  4. The TS port applies the change in the Active Directory domain and, for a new or reset password, writes unicodePwd over the setPassword channel.

  5. The result is written back into the Identity Store, so that the state of the target system entry reflects what happened in the domain.

  6. The event port publishes the change as a JMS event for applications that listen to provisioning events; the notify port sends the configured e-mail notifications.

  7. Requests that fail permanently are handed to the error activity, which reports them by e-mail.

The workflow is delivered inactive (dxmActive is FALSE). Copy it into your own scenario, connect the copy to your connected directory and activate the copy.
