Error code: 8007200a
Possible Cause:
1. The error message occurs when there is an improper header specified in the CSV File. Request you to make sure exact LDAP headers are used in the CSV file, which would resolve the issue.
2. If you have extended schema and configured custom LDAP attributes, we need to verify and confirm the datatype/value of those attribute match the requirements.
Resolution:
Please use the following link to see the proper usage of LDAP attributes that must be matched in the CSV Headers while performing the Modify Bulk Users management action through CSV import.
