If it gets through and the ident server doesn't respond within the 30 second timeout, it drops you again. If it connects and gets a 'Warm-Fuzzy' or an error of some sort, it drops you. If it gets a non-UNIX username response, it kicks you out. Basically, to use a well connected irc server, you *must* run an identd that returns a valid username response, and that username is used in your conversations. Some servers will let you on without a fully functional identd, but in my experience they seem to be the most unreliable as they are the most abused. ISP's run identd on their shell servers. That's so that when their servers get banned from IRC, they can find out which of their shell users from their shell users to have taken out and shot.
