LDN - Luminis Developer Network

Recently implemented SSO to OWA in test and production. When installed on production, received a popup window for the user to enter in external acct password and save this info to the secret store. This did not occur on our test system, is there settings that control this feature. What have other schools done to get by this popup sine we don't want to inconvience users with additional info to input? Please give me suggestions and/or let me know how your school implemented SSO to OWA and any issues encountered. See attachment for popup window details. Thanks.
