Receiving unknown error during SSO SAML Configuration

[Dim_No]

Hello,

We tried to enable the SAML SSO on Splunk,

We thought it's simple cause of the swap of both xml configuration data but that's not working at all.
When we log in, we are redirected on an unknown server.

We have SSO on many others applications without encountering that problem and without that URL "sh-i-XX".

Could someone whose enabled SSO help me ? 

Below the conf created automatically with XML Files.

Thanks a lot,

Dimitri
