Shibboleth Developers

Hi,

I am new to Shib and currently testing a service provider (Shib 2.2) against 
Test Shib. However, there is an error coming up when accessing the secure 
resource. 

Error is 'No MetaDataProvider Available'.

Log file contents are as follow.
 
2009-06-23 09:20:10 INFO OpenSAML.MetadataProvider.XML : loaded XML resource 
(http://www.testshib.org/metadata/testshib-two-metadata.xml)
2009-06-23 09:20:11 ERROR OpenSAML.MetadataProvider.XML : metadata intance 
failed manual schema validation checking: AttributeAuthorityDescriptor must 
have at least one AttributeService.
2009-06-23 09:20:12 CRIT Shibboleth.Application : error building/initializing 
MetadataProvider: Metadata instance failed manual schema validation checking.
 
Seems like metadata file validation is failing. Any idea, what is wrong? Any 
help will be greatly appreciated as I have been stuck on this problem for 
last 4 hours.


UPDATE:

I have uninstalled 2.2 and installed 2.1. It has started to work. Any idea, 
what am I doing differently in 2.2 that is causing this error?
