Can anyone give me any pointer as to what are the steps I need to setup while accessing an external application from Salesforce, which uses Ping One service for their SSO?
The requirements are mentioned on the PingOne data sheet. Apart from that, the key is which technique are you actually using to authenticate with SSO. Whether it is
- Assertion contains User's salesforce.com username
- Assertion contains the Federation ID from the User object
The 2nd option is more common and you'll need to configure it in a manner similar to what's shown below.
