Estou tentando usar o Shibboleth SP (64 bits no Windows Server 2008 R2) para autenticar com o ADFS 2.0 (Windows Server 2008 R2 de 64 bits).
Quando eu navego para o site protegido do Shibboleth, recebo um erro 500 com o seguinte no log do native_warn do Shibboleth:
2014-12-08 14:44:28 ERROR Shibboleth.Listener [2648] isapi_shib: remoted message returned an error: Unable to locate metadata for identity provider (https://adfs.int.example.com/adfs/ls/)

No log nativo, isso mostra que os metadados foram carregados:

See https://wiki.shibboleth.net/confluence/display/SHIB2/NativeSPRequestMapHowTo for help.
Apache users should rely on web server options/commands in most cases, and can remove the
RequestMapper element. See https://wiki.shibboleth.net/confluence/display/SHIB2/NativeSPApacheConfig

Controls session lifetimes, address checks, cookie handling, and the protocol handlers.
You MUST supply an effectively unique handlerURL value for each of your applications.
The value defaults to /Shibboleth.sso, and should be a relative path, with the SP computing
a relative value based on the virtual host. Using handlerSSL="true", the default, will force
the protocol to be https. You should also set cookieProps to "https" for SSL-only sites.
Note that while we default checkAddress to "false", this has a negative impact on the
security of your site. Stealing sessions via cookie theft is much easier with this disabled.

The default settings can be overridden by creating ApplicationOverride elements (see
the https://wiki.shibboleth.net/confluence/display/SHIB2/NativeSPApplicationOverride topic).
Resource requests are mapped by web server commands, or the RequestMapper, to an
applicationId setting.
Example of a second application (for a second vhost) that has a different entityID.
Resources on the vhost would map to an applicationId of "admin":

Eu tentei carregar um arquivo de metadados local e tenho os mesmos resultados. Eu também comentei ambos os tipos de linhas de metadados, e recebo o seguinte erro no log native_warn, então parece que os metadados estavam sendo carregados:
2014-12-08 14:57:31 ERROR Shibboleth.Listener [2648] isapi_shib: remoted message returned an error: No MetadataProvider available.
2014-12-08 14:57:31 ERROR Shibboleth.ISAPI [2648] isapi_shib: No MetadataProvider available.
Neste momento, não tenho certeza se há um problema com os metadados fornecidos pelo ADFS 2.0.
Eu não posso colar tudo aqui (devido a um limite de caracteres). Existe uma certa seção que eu deveria estar verificando?
