Reset password for some user from admin account problem

I need to change password for one of my users in new YouTrack 6.0. When I go to Users -> SomeUser -> Profile, there is a link "change password". This link redirecting me to hub page, to the hub user profile. In this profile I can change password for hub, and if this user logging in from hub - everything is fine, but he can't login from youtrack itself. How can I manage it?
