When logged in as an AD user that is allowed using an AD group in NPM, I am unable to modify the NCM credentials and have them persist. They work for that session, but when I logout and back in, they are gone.
I have updated the group's CirrusISUserName, CirrusISPassword, and CirrusIsFirstTime in the table UserWebSettings with a user/pass for NCM and now anyone in that group users those credentials, which is quite nice - only update them once. Would be nice if that could be modified in the user's (or group's) settings in Account Manager.
