Questions about UW POP/IMAP

greetings sorry for the cross post. this question is also in the Mail forum. i am following the this Article: https://www.afp548.com/Articles/Jaguar/postfix2.html I have just completed Step 1 xinetd has started and i have a running pid. Now,... i guess the IMAP/POP file are already installed because i never installed them. i only upgraded pine to 4.55 ( as per the Article) When the User trys to access the pop or imap account the username or password is not recognized. Since my user exists only in Netinfo do i have to export him to a flatfile? ( I don't think i should have to do this ). osx 10.2.6 server any assistance is helpful.
