Is your feature request related to existing pfSense functionality that is missing from the API? Please describe.
api/v2/vpn/openvpn/client_export

Describe the solution you'd like
It would be a valuable enhancement to extend the OpenVPN client export API to support domain users in addition to local users.

Currently, exporting OpenVPN configurations via the API works correctly for local users. However, it does not appear to support users authenticated through an external identity source (e.g., LDAP/Active Directory).

Adding support for domain users would improve automation capabilities and bring feature parity with environments that rely on centralized authentication.

Additional context
In environments where pfSense is integrated with directory services (such as Active Directory), administrators often need to automate VPN configuration distribution for domain users. At the moment, this limitation requires manual workarounds or prevents full automation.
