IBM Tivoli Directory Integrator enables synchronization, transformation, and migration of generic and identity data across heterogeneous systems. Tivoli Directory Integrator helps organizations maintain consistent and trusted data across multiple resources and provides:
- Plug-ins for several popular identity stores such as IBM Tivoli Directory Server, Domino (Http Password only), Microsoft™ Active Directory, and SunOne. These plug-ins securely capture passwords and make them available for processing for AssemblyLines.
- An infrastructure and several ready-to-use components for solutions that synchronize user passwords in heterogeneous software environments.
A password synchronization solution built with Tivoli Directory Integrator can intercept password changes on several systems. Synchronization is achieved through the Tivoli Directory Integrator AssemblyLines, which can be configured to propagate the intercepted passwords to desired systems.
IBM Tivoli Identity Manager provides the software and services to deploy policy-based provisioning solutions. This product helps companies automate the process of giving employees, contractors, and business partners access rights to applications they need, whether in a closed enterprise environment or across a virtual or extended enterprise.
With Tivoli Identity Manager you can efficiently manage policies, which are sets of organizational rules and logic, for passwords. A password policy defines the password strength rules that are used to determine whether a new password is valid. Tivoli Identity Manager password policies let you control the way passwords can be changed or generated, synchronized, and set throughout the system.
The Tivoli Identity Manager integration for the password synchronizer allows intercepted passwords to be verified by a password management policy defined in Tivoli Identity Manager prior to synchronization. Password synchronization incorporates password complexity checking using Tivoli Identity Manager password policies.
In this article, learn how the Tivoli Directory Integrator Password Synchronizer Plug-in can be integrated with Tivoli Identity Manager for password strength validation through Tivoli Identity Manager's password policies prior to synchronization. Follow along with detailed steps for:
- Installing and configuring Tivoli Directory Integrator password plug-ins
- Configuring Tivoli Identity Manager middleware
- Installing and configuring Tivoli Identity Manager
- Configuring Tivoli Directory Integrator for password synchronizer
- Configuring Tivoli Identity Manager password policies
- Testing Tivoli Directory Integrator password plug-ins

Configure Tivoli Directory Integrator Password Synchronizer
This section explains how to integrate Tivoli Directory Integrator with Tivoli Identity Manager for the Tivoli Directory Server Password Synchronizer.
Tivoli Directory Integrator can be integrated with Tivoli Identity Manager for the Sun Directory Server password synchronizer, the IBM Tivoli Directory Server Password Synchronizer, the Windows password synchronizer, and password synchronizers for UNIX and Linux.
The Tivoli Identity Manager integration for the password synchronizers allows synchronized passwords to be verified by a Tivoli Identity Manager server's password strength servlet prior to synchronization. This allows password synchronization to incorporate password complexity checking using Tivoli Identity Manager password policies.
Before starting configuration, ensure that the Password Plugin for Tivoli Directory Server is installed.
- Edit the pwsync.props file from the <TDI_Install_Dir>/pwd_plugins/tds/ directory.
Modify the Tivoli Identity Manager Integration section of the file, as shown in Figure 23, with the Tivoli Identity Manager URL,
PrincipleName, password, and Tivoli Identity Manager service Name below.
- itimPrincipalName=ITIM Manager
- itimPrincipalPassword=ITIM Manager password is encrypted using the encryptPasswd.bat/sh utility (see EncryptPassword utility).
- itimSourceDN=erservicename=TDIPasswordService, o=IBM, ou=IBM, dc=com
Figure 23. pwsync.props
The Tivoli Identity Manager password URL can be either or https (SSL communication).
For Tivoli Directory Integrator to Tivoli Identity Manager communication over SSL, you need to create and extract certificates from Tivoli Identity Manager, which is deployed on WebSphere Application Server, and import these certificates into Tivoli Directory Integrator certificates.
- Click here for details on tasks to be performed on Tivoli Identity Manager (WebSphere Application Server).
- Click here for details on tasks to be performed on Tivoli Directory Integrator.
After you've completed the previous two steps, go to the pwsync.props file and modify the SSL configuration properties with appropriate values, as shown in Listing 2.
Listing 2. pwsync.props - SSL configuration properties
# SSL configuration properties # # javax.net.ssl.trustStore= # javax.net.ssl.trustStorePassword= # javax.net.ssl.trustStoreType= # javax.net.ssl.keyStore= # javax.net.ssl.keyStorePassword= # javax.net.ssl.keyStoreType=
Restart the Tivoli Directory Server and Tivoli Directory Integrator server.
The passwords referenced in the pwsync.props file must be encrypted using the EncryptPassword utility, as shown in Listing 3.
Listing 3. EncryptPassword utility
Similarly, the following should also be encrypted using the encryptPasswd.bat/sh script:
If these values are not encrypted, you'll see the error shown in Listing 4.
Listing 4. Error while changing password
com.ibm.di.plugin.pwstore.itim.policy.MalformedResponseException: org.xml.sax.SAXParseException: Element type "SYNCH_PSWDS_RESP" must be followed by either attribute specifications, ">" or "/>".
itimSourceDN/ServiceDN is the name of the service against which the
password check would be performed. The format is:
- Specifies the name of the target service used by the IBM Tivoli Identity Manager server.
- Specifies the name of the organization on the IBM Tivoli Identity Manager server.
- Specifies the short name defined for the organization during installation and configuration of the Tivoli Identity Manager server. If this value is not known, it can be determined by opening the LDAP configuration tool for your product. Locate the new root suffix created during the Tivoli Identity Manager installation.
- Specifies the root of the directory tree.
Although DN formatting is used for the Service DN value, this DN is not the DN of the service that is being monitored. These values are parameter values to the Password Synchronization plug-in.
For example, if you installed the Tivoli Identity Manager server in the root LDAP suffix called ISIM, and your Windows Active Directory service is named WinAD Corp Server and is installed in an organization named Finance Org, the Tivoli Identity Manager organization chart looks similar to Figure 24.
Figure 24. ITIMSourceDN/ServiceDN
This Windows Active Directory Adapter example has the Service DN value shown in Listing 5.
Listing 5. ITIMSourceDN/ServiceDN example
erservicename=WinAD Corp Server,o=Finance Org, ou=ITIM,dc=com
Configure the Password Synchronizer to use a Tivoli Identity Manager
Decorator by setting the
pwsync.props to one of the Decorator classnames in Listing 6.
Listing 6. pwsync.props
com.ibm.di.plugin.pwstore.ldap.LDAPPasswordStoreITIMDecorator com.ibm.di.plugin.pwstore.ldap.JMSPasswordStoreITIMDecorator com.ibm.di.plugin.pwstore.log.LogPasswordStoreITIMDecorator
For testing purposes, we selected
LogPasswordStoreITIMDecorator, which should not be used in
a production environment.
You must configure LDAP/JMS for production use, as in
Figure 25, using
Figure 25. pwsync.props
When Tivoli Identity Manager integration is enabled,
checkRepository must be set to true in the Password Synchronizer
configuration file (pwsync.props).
- After pwsync.props is updated, restart the Tivoli Directory Server instance. Ensure Tivoli Directory Server is running in normal mode; it should not be running in Config mode.
- If the Tivoli Directory Server server is running in Config mode, check the Tivoli Directory Server log plugin.log/proxy.log for error details.
Configure Tivoli Identity Manager password policies
Use the steps in this section to set up the password policies for Tivoli Identity Manager.
- Log in to the Tivoli Identity Manager console, as in Figure 26. Typically, the URL is
Figure 26. Log in to Tivoli Identity Manager Console
- After you're logged in to the Tivoli Identity Manager console the Home window displays.
In this window, select Manage policies > Manage
Password Policies, then click Create to create a new password
policy, as in Figure 27.
Figure 27. Manage Password Policy
- The window entitled Manage Password Policies opens. From the
General tab in this window, create a new password policy by entering
TDIPasswordPolicyin the Name field and
IBMin the Business Unit field, as shown in Figure 28. Click the Targets tab.
Figure 28. Define password policy
- The Targets window opens. In this window, select the available
ITIM Service and click Add, as shown in Figure 29.

Figure 30. Define Policy Rules
The Tivoli Identity Manager password policy is now configured.
Test the Tivoli Directory Integrator password plug-ins
This section describes how the Tivoli Directory Server user password changes are intercepted by the Tivoli Directory Integrator password plug-in and how these passwords are validated by Tivoli Identity Manager using the password policies.
- Ensure that Tivoli Directory Server, the Tivoli Directory Integrator proxy, and the Tivoli Identity Manager services are running correctly.
Using the LDAP Client, try to modify the user password for user
test1. It should have
userpasswordas an attribute, as in Listing 7.
- The command will fail and provide the message
ldap_modify:plugin function failed. The password for user test1 is
test1, which is not a length of 8. It also doesn't have any special characters, which is defined in the Tivoli Identity Manager password policies section.
Listing 7. ldapmodify command
idsldapmodify.cmd -p 1389 -D cn=root -w password dn: cn=test1,o=ibm,c=in objectClass: top objectClass: person objectClass: organizationalPerson cn: test1 sn: test1 userpassword: test1 Results:- Operation 0 modifying entry cn=test1,o=ibm,c=in ldap_modify: Unknown error ldap_modify: additional info: plugin function failed
- Check the proxy.log file for details. You will see
com.ibm.itim.policy.passwordpolicyAuthority.PASSWORD_RULE_VIOLATION, as shown in Figure 31.
Figure 31. Proxy.log output
- Check the plugin.log file, which will show the following results, as
shown in Figure 32.
The Proxy response represents error.
Pre-operation on modify:PWPROXY_ERROR_PROTOCOL_PASSWORD_OP_FAILED.
Pre-operation on modify: Will cancel LDAP Modify operation for 'cn=test1,o=ibm,c=in'.
Figure 32. Plugin.log output
- Try to change the Tivoli Directory Server user password with an
appropriate password, per the policy, as shown in Listing 8.
Listing 8. ldapmodify command
idsldapmodify.cmd -p 1389 -D cn=root -w password dn: cn=nagesh,o=ibm,c=in objectClass: top objectClass: person objectClass: organizationalPerson cn: nagesh sn: bhagwat userpassword: passw0rd# Results:- Operation 0 modifying entry cn=nagesh,o=ibm,c=in
- Check the proxy.log file, which will show the result
Storing the password notification for user: 'cn=nagesh,o=ibm,c=in' with password: 'passw0rd#'', as shown in Figure 33.
Figure 33. Proxy.log output
- Check the plugin.log file, which will show
PostModOperation: Proxy response is successful, as shown in Figure 34.
Figure 34. Plugin.log output
Similarly, users can specify
- Users need to configure LDAP as a password store in the pwsyn.props
file. (See LDAP as a Password Store in Resources for more details.)
The password will be stored under the LDAP Server. Users can read the password from the LDAP Server using the Tivoli Directory Integrator LDAP connector and can update into other data sources, thus achieving password synchronization.
For more details on how to read the password from the LDAP Server, see Appendix A in Synchronizing users between Microsoft Active Directory Server and IBM Domino Server using Tivoli Directory Integrator.
- Users need to configure JMS as a password
store in the pwsyn.props file. (For more details, see
JMS Password Store.)
The password will be stored under MQe. Users can read the password from MQe using the Tivoli Directory Integrator MQe/JMS Password store connector and can update into other data sources, thus achieving password synchronization.
For more details and a sample solution that reads a password from MQe and updates it into the Active directory, see Section 4, "Creating Tivoli Directory Integrator AssemblyLine" in Password Synchronization between Microsoft Active Directories using Tivoli Directory Integrator.
You're now finished integrating the Tivoli Directory Integrator Password Plug-in with Tivoli Identity Manager for the password strength validation through Tivoli Identity Manager's password policies prior to synchronization.
This article walked you through a step-by-step solution for integrating the Tivoli Directory Integrator password synchronizer with Tivoli Identity Manager for password policy strength and validation before passwords get into the password store for further synchronization.
