Look this:

root 29723 1 0 Jun04 ? 00:00:13 /usr/sbin/dovecot root 29724 29723 0 Jun04 ? 00:00:03 dovecot-auth dovecot 25239 29723 0 Jun05 ? 00:00:00 managesieve-login dovecot 19097 29723 0 Jun06 ? 00:00:00 managesieve-login dovecot 19114 29723 0 Jun06 ? 00:00:00 managesieve-login dovecot 17952 29723 0 09:14 ? 00:00:00 pop3-login dovecot 18130 29723 0 09:16 ? 00:00:00 imap-login dovecot 18252 29723 0 09:17 ? 00:00:00 imap-login dovecot 18317 29723 0 09:18 ? 00:00:00 pop3-login dovecot 18438 29723 0 09:19 ? 00:00:00 pop3-login dovecot 18495 29723 0 09:19 ? 00:00:00 imap-login

root is the user that executed /usr/sbin/dovecot dovecot is the user "login_user" in dovecot.conf

and "user" in dovecot.conf .... auth default: user: santhosh passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd .... in your case "santhosh", is the user to access to /etc/passwd.dovecot and /etc/passwd files but if the passwords are shadows, the user to access a /etc/shadow must be ROOT.

Thanks in advance
