Question

Active Directory

With the next periodic password change, users began to experience such an error. As usual, first a window appears, ala "Before the first login, the user must change his password", then we correctly enter the desired characters. And after clicking "OK" appears "Invalid username or password". And it happens on this server - windows server 2008. If you do the same thing on another domain server, then everything is OK - the password is successfully changed. Essno domain account. Where to dig?
