Overview
The following error message appears in the Okta dashboard while trying to provision a user from Okta to Active Directory:
An error occurred while provisioning exampleuser@gmail.com. Automatic provisioning of user Example User to app Active Directory failed: Error provisioning active_directory user: An invalid dn syntax has been specified. Please fix this on the Tasks Page
Applies To
- Active Directory (AD)
- Profile Editor
- Universal Directory
- Provisioning
- Lifecycle Management
Cause
This error mainly occurs when there are blank spaces after or before the first name, last name, email, or username on the Okta profile of a user.
Solution
It is difficult to spot unwanted blank spaces just by viewing the affected Okta user profile directly. For a more efficient approach, follow these steps:
- Access Directory > Profile Editor.
- Then click on Directories on the left-hand panel.
- After that, click on Mapping for Active Directory and do a preview of the user to spot the blank space.
- After the blank space is located, go to the Okta profile of the affected user and edit it (remove the unwanted blank spaces).
- Check for blank spaces on other attribute values as well.
- Once they are removed, retry the provisioning task under the page Dashboard > Tasks for that user.
