This application is done in PHP and configured for SP-Initiated SAML.

The following are the settings used to setup the connector.

Menu URL: append /auth/saml/ to the FQDN.  An example would be https://customer.simpllms.com/auth/saml/
IdP URL: should be auto generated
IdP Entity ID: should be auto generated
ACS URL: Once you get the SP entity ID from the Vendor you would append it on the end of this URI (/auth/saml/saml2-acs.php/).  The full URL would look something like this, https://customer.simpllms.com/auth/saml/saml2-acs.php/alphaNumericSpEntityId

SP Entity ID: Vendor supplied

The Identifier type is setup as Email Address.  You would then choose the associated user store and attribute.

This application uses the Extended SAML attribute contract.  To configure this click on the attribute tab and check the box to enable the Extended SAML attribute contract.  Once it is enabled you can click on the green plus to add a new attribute. You need to set the new attribute to be a user store source with an attribute name of "uid" and the corresponding attribute value set to the user store element. 

The main user store tab and policy tab would be configured like any other application.
