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.
- Function signatures inside SAML class were fixed
- Redirect URL for /saml/login path was modified (saml_authorized -> index.saml_authorized)
Current status is that SAML metadata can be generated under /saml/metadata and communication to SAML iDP is working
Problems remaining:
- SAML Response doesn't contain any attributes (There is no AttributeStatement on the Response). It can be that problem is on iDP side
- Background thread in retrieve_idp_data() cannot be spawned, this part is currently commented out, old code needs to be revisited
