Remote certificate is invalid error

Remote certificate is invalid according to the validation procedure

So the problem is that Identity Server 3 and Sitefinity need a valid SSL Cert in order to let you into the backend.  The KB docs are crazy weak on detail.

The good news is that creating a local one for development is pretty easy to do.  Lets assume we’re wanting to secure our new “dev.mysite.com” setup in IIS.

1. Open Powershell as Administrator (right-click on it)

2. Run this

   New-SelfSignedCertificate -DnsName “dev.mysite.com”, “dev.mysite.com” -CertStoreLocation “Cert:\LocalMachine\My”

3. Open the “Manage computer certificates” window (through start\programs, cortana search, whatever)

4. Your cert should be under Personal->Certificates, click on it, find your cert

5. Right-click->All Tasks->Manage Private Keys

6. Give your sites App pool access (Example: iis apppool\dev.mysite.com), save up

7. Right-click the cert and Copy

8. Now expand Trusted Root Certification Authorities->Certificates

9. Paste your cert into here

10. Now open your Sitefinity AuthenticationConfig.config, and put this into it

11. Don’t forget to edit your IIS bindings to use this new https certificate

12. 1. Open IIS

13. Click your site

14. Click Bindings

15. If https is not here click Add (or if it is, select and hit edit)

16. Fill in the details, choose the new dev.mysite.com cert in the bottom SSL dropdown.
