Devise provides an update_without_password method that you can use when updating a user if no password is entered. Using that method, you can customize the update method in your ActiveAdmin users controller.

 def update
   @user = User.find(params[:id])
   if params[:user][:password].blank?
     @user.update_without_password(params[:user])
   else
     @user.update_attributes(params[:user])
   end
   if @user.errors.blank?
     redirect_to admin_users_path, :notice => "User updated successfully."
   else
     render :edit
   end
 end

The Devise Wiki has more information about this method if your interested.
