[Dovecot] login_log_format_elements does not appear to be changing log format 2.2.5

[Chris]

Hi,
login_log_format_elements does not seem to change the login logs.  I 
have it set to the below setting and the word "home" does not even 
appear.  Is there something I have to do to for this?  Also I use ldap 
for authentication.

[user at MB1 logs]$ doveconf -n | grep -i log
debug_log_path = /home/user/apps/logs/dovecot_debug.log
info_log_path = /home/user/apps/logs/dovecot_info.log
log_path = /home/user/apps/logs/dovecot.log
login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c 
home=%h
service imap-login {
   chroot = login
   executable = imap-login
   type = login
   user = $default_login_user


[user at MB1 dovecot]$ tail -1 ~/apps/logs/dovecot_info.log
Sep 04 18:19:55 imap-login: Info: Login: user=<test2 at domain.local>, 
method=PLAIN, rip=10.100.5.6, lip=10.100.5.103, mpid=6571
