I am a server admin and a gallery curator and have all the permissions set to yes.
We authenticate using active directory.
I saved a workflow to my private studio with option to require credentials when it runs.
I try to run it and my userid or password is not accepted
I am certain I typed my password correctly

I get the same response from trying to store gallery credentials with my AD userid and passwort
I also tried including my domain before userid and get same response
I recently noticed, the gallery id's in windowsidentities table are wrong and don't match the correct ones in the users table. i read later that windowsidentities was obsolete but thought it may be worth mentioning.
