The cause of this error is an incorrectly specified entity type in the organization settings and in the connection settings to the ESF IS. If you actually operate as a sole proprietor, but somewhere in the system a legal entity indicator is set, the ESF server will not allow the operation to be performed on behalf of the entrepreneur.
To fix this, you need to check and correct two places:
1. In the employee's organization card — change the type from "Legal Entity" to "Individual" (sole proprietor).
2. In the "Users" section of the ESF IS connection — change "Employee Type" to "Sole Proprietor (Manager's Digital Signature)".
Once both parameters are brought into alignment, the ESF submission should go through without the insufficient authority error.
Frequently Asked Questions
Why does this error occur if everything worked fine before?
Usually this is related to the fact that when the organization or employee was set up in the system, the wrong type was initially selected (Legal Entity instead of Individual), and as long as the data wasn't thoroughly checked, the error didn't show up — until the moment of ESF submission, when the server starts verifying authority based on the digital signature.
Do I need to reissue the digital signature after correcting the employee type?
No, the manager's digital signature remains the same — only the employee type in the ESF IS connection settings changes, the digital signature itself is not affected.
What should I do if the error persists after the fix?
You should double-check that both changes — in the organization card and in the ESF IS user settings — are saved correctly and relate to the same employee/sole proprietor.
