WordPress MU

The XMLRPC returns me:

Array ( [faultCode] => 401 [faultString] => Sorry, you cannot add new pages. )

for a user I created and who is admin for his blog.
I have the correct blog ID and I login as this user.
I use the XMLRPC.php url from the root so http://x.com/xmlrpc.php

I do not understand this message since the user is administrator on his own blog.

So this is from the check:

if ( !current_user_can("publish_pages") )
			return(new IXR_Error(401, __("Sorry, you cannot add new pages.")));

I dont understand why the user has no rights to publish pages, he is administrator on his own blog?

I did a check with WLW and with this one I can create pages for this user. I dont really see the difference my call looks like this:

<?xml version="1.0" encoding="utf-8"?>
<methodCall>
<methodName><![CDATA[wp.newPage]]></methodName>
<params>
<param>
<value>
<string><![CDATA[8]]></string>
</value>
</param>

<string><![CDATA[username]]></string>

<name><![CDATA[description]]></name>
<value>
<string><![CDATA[<?php $objectname = "a"; include_once "bla.php"; ?>]]></string>
</value>
</member>

<member>
<name><![CDATA[permaLink]]></name>
<value>
<string><![CDATA[somename]]></string>
</value>
</member>
<member>
<name><![CDATA[wp_page_parent_id]]></name>
<value>
<int><![CDATA[5]]></int>
</value>
</member>
</struct>
</value>
</param>
<param>
<value>

<string><![CDATA[1]]></string>
</value>
</param>
</params>
</methodCall>

I got it , I do not take the Blog ID as in "overall blog id" but the blod id # of the particular user, in this case 1...

SOLVED.
