Cannot create Database with RPC

[VanFanel]

Hello everyone,

i try to create a new database over the RPC-API on a Plesk 11.0.9 Update #41 with an reseller account.

If i log into the reseller account with plesk and create a database over the Plesk-Interface everythink works fine and i can create the database, but if i send these package:

<packet version="1.6.0.0">
<database>
<add-db>
<domain-id>DOMAIN_ID</domain-id>
<name>DATABASENAME</name>
<type>mysql</type>
</add-db>
</database>
</packet>

with the reseller account i get this feedback:

<?xml version="1.0" encoding="UTF-8"?>
<packet version="1.6.0.0">
<database>
<add-db>
<result>
<status>error</status>
<errcode>1006</errcode>
<errtext>Permission denied.</errtext>
</result>
</add-db>
</database>
</packet>


With the Plesk interface it works perfect, but over RPC nothing happens.

If i use the Administrator Login and NOT the resellers login it also works over the RPC Protokoll and i get:

<?xml version="1.0" encoding="UTF-8"?>
<packet version="1.6.0.0">
<database>
<add-db>
<result>
<status>ok</status>
<id>7</id>
</result>
</add-db>
</database>
</packet>

I also checked the permission of the reseller, and the Flag "Use of Remote-API" is set to true and has a green Check.
And if i try to create a new domain over the RPC Protrokoll it also works, so the RPC Function seems to be activated.

EDIT:

I tried these one, too :
<packet version="1.6.3.0">
<database>
<add-db>
<webspace-id>WEBSPACE_ID</webspace-id>
<name>DATABASENAME</name>
<type>mysql</type>
</add-db>
</database>
</packet>

With admin account: works fine, with the reseller account: permission denied

/EDIT

EDIT 2:
I tried it with an costumer account and surprising: it works. A costumer can create databases over RPC, so why is it not possible for the resellers?
/Edit 2

So i searching for a solution to give the reseller the permission to create databases over RPC,

someone has an idea or a solution?
