Integration (AddUser)

Hi all!

I need to integrate OGO with my software. I'm trying to create user 
account's on OGO with a XMLRPC client but without success. I'm starting 
now with XML and when I try to execute this simple script below:

---
#!/usr/bin/python
import xmlrpclib

server = 
xmlrpclib.Server('http://localhost:20000/RPC2',login='root',password='xxx')
LastName = "Fontana"

result = server.person.fetch({'qualifier':'name like "' + LastName + 
'"','sortOrderings' : ['name',],})
---

I receive the login page in html, no xml!?

My script above send this data to server:

---
POST /RPC2 HTTP/1.0
Host: groupware:20000
User-Agent: xmlrpclib.py/1.0.0 (by www.pythonware.com)
Authorization: Basic cm9vdDpQTEBJc1AyMDAy
Content-Type: text/xml
Content-Length: 379

<?xml version='1.0'?>
<methodCall>
<methodName>person.fetch</methodName>
<params>
<param>
<value><struct>
<member>
<name>sortOrderings</name>
<value><array><data>
<value><string>name</string></value>
</data></array></value>
</member>
<member>
<name>qualifier</name>
<value><string>name like "Fontana"</string></value>
</member>
</struct></value>
</param>
</params>
</methodCall>
---

I receive from python this error of parser
on line "result = server.person.fetch({'qualifier':'name like "' + 
LastName + '"','sortOrderings' : ['name',],})":

xml.parsers.expat.ExpatError: undefined entity: line 39, column 48

I suspect that this error is caused because script receives html and not 
xml.

I do not know what to make. The RPC in the server is enable by default?  
If no will be, as I make to enable this?  Somebody can help me?

Sorry by my poor English.
