Users are getting an ‘Incorrect username and Password’ message while logging on through Storefront. The following messages appear in the event viewer on the Storefront Servers
‘An authentication attempt was made for user: username that resulted in: Failed (Windows Error Code: 1326)
Password expiry information was requested but none was returned’
Users confirm that they can login to the other applications like outlook or teams etc with the same password, but for the storefront portal login, it doesnt work.
Solution: Reset user’s AD password. This should resolve the issue.
