state 2 = "waiting for auth data from client", so what it means is that the client sent:

and then just didn't do anything.

You can safely ignore it. It should have been logged with "info" level and only with auth_verbose=yes. Although I guess the message could be a bit nicer. This is better I think: http://hg.dovecot.org/dovecot-2.1/rev/49bb6cc43d03
