Usuario nao foi autenticado

The application do:
1 --> take de uid form user an password
2 --> make a search with a filter and base:
      String filter = "(uid=" + usuarioID + "*)" ;
      String base = "dc=ufmg,dc=br";
3 --> get the cannonical name(CN) and close the connection.
4 --> now, the SSL connection is create with CN user and the password.
5 --> and work`s fine.

But, how i told previous, the exception appears without frequency 5 or 7
times.
Some body, could help me.
Is this a version problem configuration or something else?
