Target Resource (or Managed Resource) vs Trusted Source (or Authoritative Source) Mode : OIM integration with applications (AD, OID, OVD, EBS, SAP, HR, LDAP)
In this post I am going to cover two modes (Target Resource or Trusted Source) that OIM uses to integrate with applications like LDAP (OID, AD, OVD, iPlanet), HR (EBS, SAP, etc), Unix (Linux, Solaris), etc.
1. Oracle Identity Manager (OIM) can be integrated with Applications (LDAP, AD, OID, HR etc) in one of two modes
a) Target Resource Mode
or
b) Trusted Source Mode
2. You configure application (AD, OID, OVD, HR) etc in Trusted Source Mode if that application is source of truth for user provisioning (All users are created in Application and OIM reconcile data from application).
3. You configure application (AD, OID, OVD, HR) etc in Target Resource Mode if that OIM is source of truth for user provisioning (All users are created in OIM and OIM then provision accounts in Application. Any changes in Application are reconciled back to OIM).

4. Target Resource mode is also called as Managed Resource mode or Account Management mode
5. Trusted Source mode is also called as Authoritative Source mode or Identity Reconciliation mode
6. To find out in what mode (Trusted Source or Target Resource) OIM 11gR1 is integrated with application
a) Login to OIM Advanced Console and click on Manage IT Resource under configuration
b) Click on Edit Link against IT Resource (that is integrated with OIM and for which you wish to see configuration)
c) Check value of Configuration Lookup
Note: Navigation is slightly different in OIM 11gR2
Value Lookup.Configuration.ActiveDirectory mean Active Directory is configured in Managed Resource Mode
Value Lookup.Configuration.ActiveDirectory.Trusted mean Active Directory is configured in Trusted Source Mode
7. In both modes (Trusted Source or Target Resources) you can reconcile data from target system in to OIM. To reconcile data from target systems, you run reconciliation schedules jobs in OIM. To reconcile data in to OIM from target system (configured in trusted source mode) you run different job like [Active Directory] User Trusted Recon scheduled job where as to reconcile data in to OIM from target system (configured in target resource mode) you run different job like [Active Directory] User Target Recon scheduled job .
8. In Target Resource mode, if a user record is deleted on the target system and Scheduled Job “[Application] Target Delete Recon” is run then the corresponding [Application] User resource is revoked from the OIM User.
Note: Target System or Application are system that is integrated with OIM like Active Directory
9. In Trusted Source mode, if a user record is deleted on the target system and Scheduled Job “[Application] Trusted Delete Recon” is run then the corresponding OIM User is deleted.
Note: Target System or Application are system that is integrated with OIM like Active Directory
