Duo Mobile for Huawei Storage Device

Hi Community,
did somebody use Duo Mobile for MFA in combination with LDAP authentication for Huawei Storage Systems (Oceanstor V6)? I have many try and errors with the LDAP configuraiton and I’m not sure if we set the correct LDAP specification for Duo Mobile.
Note LDAP works fine on the storage device without the Duo Mobile Proxy.

Thank you
