I created my custom Data Connector wich simply extends 
JNDIDirectoryDataConnector(IDP V 1.3)
I 'd like to init in my resolver.xml file like this :


<CustomDataConnector id="ldap" 
class="com.xxx.JNDIDirectoryDataConnectorExtends">
         
                <Search filter="uid=%PRINCIPAL%">
           <Controls searchScope="SUBTREE_SCOPE" returningObjects="false" />  
   
                </Search>
                <Property name="java.naming.factory.initial" 
value="com.sun.jndi.ldap.LdapCtxFactory" />
                <Property name="java.naming.provider.url" 
value="ldap://ldap1.xxxxxx"; />
                <Property name="java.naming.security.principal" value="xxxxx" 
/>
                <Property name="java.naming.security.credentials" 
value="xxxx" />

</CustomDataConnector>

But when I test with resolvertest program I have this error :

ERROR edu.internet2.middleware.shibboleth.aa.attrresolv.AttributeResolver  - 
Error parsing Attribute Resolver Configuration file: 
org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was 
found starting with element 'Search'. One of 
'{"urn:mace:shibboleth:resolver:1.0":DataConnectorDependency, 
"urn:mace:shibboleth:resolver:1.0":AttributeDependency, 
"urn:mace:shibboleth:resolver:1.0":FailoverDependency, 
WC[##other:"urn:mace:shibboleth:resolver:1.0"]}' is expected.

shibboleth-resolver-1.0;xsd Schema is wrong ?
How could use my custom  JNDIDirectoryDataConnector ?

Thanks for your help
