Publlishing email to Edir

on both my test and production 2014 I have Ldap sync enabled, I also have Publish email address checked under System | ldap server
in viewing MTA logs ldap connection occurs during scheduled event. Info changed in LDAP updates in GW, but if a GW account is renamed I never see the setting Internet Email Address on the general page update in IMgr. Is that not the field Publish email address is updating from GW to Edir?
