[bug] invalid account error solved for local auth

• set up local option for auth
• leave the local attribute mapping field down below set with its autopopulated {{ .password }}
• create a new user
• try logging in and get the invalid account error here

Solution: that local attribute mapping field needs to be the main password you set up for filestash. This is not made clear by a tooltip or description here which would save a lot of people heartache and hours of troubleshooting and claude credits! ;-)
