If it opens a connection it has to try if it can open the directory you're 
trying to access. So you should do a smbc_opendir() on the share or directory.

If the authentication fails libsmbclient calls the auth_fn callback.

I suggest to use smbc_opendir() to check if you can access the share. If 
you're not authenticated or the username/password are wrong the auth_fn will 
be called.
