Hi Sakit,
After step #1 oxAuth stores specified with method `getExtraParametersForStep` paramters from identity.workingParameters in session.
To access them later you can use next pattern:
`
identity.getSessionId().getSessionAttributes()
super_gluu_request = session_attributes.get("super_gluu_request")
`
Thank you for feedback. I will think about to add automatically stored parameters in session to identity.workingParameters to allow access them transparently from any step.
