The script defaults to impersonating an Office365 Azure based SP. Override by specifying the EntityID of the SP you wish to impersonate in the ENTITYID environment variable.

You also need to specify the registered endpoint that the request is pretending to come from. Again, this defaults to the Office365 endpoint. Override with ENDPOINT.

You MUST specify a URL to make the request against. For a Shibboleth IDP this probably looks like https://idp.example.com/idp/profile/SAML2/SOAP/ECP.

Example

The values for ENTITYID and ENDPOINT are the defaults.

CRED=user:pass \
ENTITYID=urn:federation:MicrosoftOnline \
ENDPOINT=https://login.microsoftonline.com/login.srf \
URL=https://idp.example.com/idp/profile/SAML2/SOAP/ECP \
