@Searinox I'm a little lost here. It sounds like you want me to get the server password from servers.ini and use it for the nickname.
If this is what you are asking I don't think it will work because most people use a different password for their nick then they have for server login.
If you are referring to "perform", it's not a good idea to store passwords here because they are stored in plain text. In edition, you would have to parse the perform block and try to figure out which line is the identify line.

Please clear this up for me so I understand exactly what it is you are asking.

As for the autojoin issue, I think this should be addressed in a properly written autojoin script. If a channel is +R and doesn't let you join, the autojoin script should react by setting a timer and attempting to rejoin in 10 seconds or something.
I will add a on connect identify to this now. Let me know if that helps any.

@Cheiron are you getting a "nickname already in use error" in this case?
If so I'm adding a raw 443 check to address this. You'll have to let me know if it resolves this issue, as I have no way of simulating this situation. Normally the notify will kick in and ghostkill the nick.
I'll post an update now.
