FastBind is enabled for the Active Directory synchronization project

Disable the FastBind option for the target system connection to Active Directory as this limits Identity Manager's ability to synchronize as not all properties are read-write.

Follow the steps below to disable FastBind for the synchronization project:

1. Open Synchronization Manager

2. Double-click on the "Active Directory Domain" synchronization project for the domain exhibiting the issue.

3. Click on Target system on the left

4. If prompted for the target system connection password, use remote system to route the connection through the job server, or provide the password manually. The user account is not provided, the administrator will need to know which user account had been specified.

5. Click Edit connection to open the AD connection wizard

6. Advance to the Credentials screen, provide the password again and click "Test"

7. On the Configure connection options disable 'FastBind'

8. Complete the wizard, no further changes should be required and then Commit to database to save the changes.
