How to remove user via Smack

I’m writing bot with admin permission, that can delete/add new users, create rooms.

I can create user like: accountManager.createAccount(username, password);

But now I’m trying to delete user. Smack allow to delete current logined user: accountManager.deleteAccount();

So, for removing another account I should open new connection and delete user using it. Are there any better solutions to remove user?
