ill assume this is the right forum for ACS questions.
having created a delegation record (which gates issuing an auth code, and refresh token), SHOULD I ever delete it ... as administrator?
Yes, I understand that deletion would prevent further issuance of refresh tokens ...and probably prevent further access token minting.
My issue is that I will shorty have a million delegation records in the entity db of the acs namespace. Should I be culling these?
No... we do not implement any kind of user federation, where users go in and remove their former-delegation.
