The new setting 'verify_ssl_connections' tells the requests library to
verify secured outgoing HTTP connections.
Usually verifying is desired and helps to reveal configuration
problems. It also disables an ugly warning when HTTPS connections
are made without verification.
Problems resolved:
- Method create_self_signed_cert() was invoked nowhere. This puts parameter "SAML_SIGN_REQUEST" description in configs/development.py as incorrect
- Method create_self_signed_cert() was returning error while trying to write out certificate and private key. File handler was opened for writing out TEXT instead of BINARY data
Enhancements:
- Two new parameters are introduced SAML_CERT_FILE and SAML_KEY_FILE. User can now explicitly define own certificate and key file anywhere on file-system.
- If parameters mentioned in previous bullet aren't explicitly defined, in PowerDNS-Admin root directory self-signed certificate will be created.
- Certificates will be used or generated in any case, because in saml.py there are explicit parameters defined which require certificate/key in order to work normally. If they aren't, exception will be thrown. Examples of parameters defined in saml.py requiring certificate: wantAssertionsEncrypted, signMetadata, wantAssertionsSigned.
