=head2 validate_user_credentials

Called from C<process_post> to process login requests (special AJAX requests)
originating from the JavaScript side (i.e. the login screen in
login-dialog.js, via login.js).

Returns a status object - OK means the login was successful; all other statuses
mean unsuccessful.
