select directory_id, lower_user_name, active from cwd_user where directory_id = '<directory_id>' AND lower_user_name not in (select lower_user_name from cwd_user where directory_id = '<destination>');ℹ️ Replace <directory_id> and <destination> accordingly.
Resolution
If the user does not exist in the directory, you can refer the following resolution steps:
Disable the current failing delegated ldap directory.
Create a new Internal With LDAP Authentication directory and leave the option Copy User on Login disabled for the moment. If needed you can go back and re-enable the copy option once this is complete.
Move the newly created directory to the top of the directory list.
Complete your migration.
