I have Dovecot2 auth setup to run as

	user  = doveauth
	group = dovecot

configured in,

	vi conf.d/10-master.conf
		...
		service auth {
			unix_listener /var/spool/postfix/private/auth {
				user  = postfix
				group = postfix
				mode  = 0660
			}
			user  = doveauth
			group = dovecot
		}
		service auth-worker {
			user  = doveauth
			group = dovecot
		}
		...

When I start Dovecot,

	ls -al /var/run/dovecot/auth-*
		/bin/ls: No match.

	service dovecot-custom start
		Starting Dovecot ...           done

Dovect's auth-process sockets are created with different ownership than
what I specified,

	ls -al /var/run/dovecot/auth-*
		srw------- 1 root    root 0 Oct 11 19:30
		/var/run/dovecot/auth-client
		srw------- 1 dovecot root 0 Oct 11 19:30
		/var/run/dovecot/auth-login
		srw------- 1 root    root 0 Oct 11 19:30
		/var/run/dovecot/auth-master
		srw------- 1 root    root 0 Oct 11 19:30
		/var/run/dovecot/auth-userdb
		srw------- 1 dovecot root 0 Oct 11 19:30
		/var/run/dovecot/auth-worker

Which causes problems when I test AUTH,

	telnet 127.0.0.1 143
		Trying 127.0.0.1...
		Connected to 127.0.0.1.
		Escape character is '^]'.
		* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR
		LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot
		ready.
	a login "xxx at domain.loc" "testpass"
		a NO [UNAVAILABLE] Temporary authentication failure.
		* OK Waiting for authentication process to respond..

In logs,

What needs to change to get those sockets created with correct/assigned
ownership & perms?
