dovecot-auth isn't (or shouldn't!) be running as "dovecot" user. See http://wiki.dovecot.org/UserIds. Also I don't think pam_limits settings matter for dovecot-auth, since it's started by dovecot master which was started as root, and PAM is never called in the middle. So the only thing that affects number of fds is "ulimit -n" value before dovecot was started. What Dovecot version are you using? How many dovecot-auth processes do you have running after a while?
