Credential failed name check.

[Johan Åkerstrøm]

I'm getting this error.

2015-08-19 16:12:47,308 - WARN [org.apache.xml.security.signature.XMLSignature:760] - Signature verification failed.
2015-08-19 16:12:47,312 - ERROR [org.opensaml.security.x509.impl.BasicX509CredentialNameEvaluator:300] - Credential failed name check: [subjectName='OU=oiosaml-sp,CN=ht
tps://saml.site.domain.com']

EntityID of the RP is: https://saml.site.domain.com but the signing cert has the following subject: 'OU=oiosaml-sp,CN=https://saml.site.domain.com' is this mismatch what is causing the error? 
If yes, can I ignore this mismatch or configure shibboleth to recognize the subject name?

Regards Johan
