I keep getting ldap errors on my install which was trying to acces port 389, but I find out that /opt/zimbra/bin/ldap starts slapd on port 7389 instead of 389 and the /opt/zimbra/conf/localconfig.xml also sets to 389 so therefore 7389 was a mistake by someone?

so line 66 on /opt/zimbra/bin/ldap should be changed from
/opt/zimbra/openldap/libexec/slapd -4 -u zimbra -h "ldap://:7389/" \
/opt/zimbra/openldap/libexec/slapd -4 -u zimbra -h "ldap://:389/" \
so the port was changed from 7389 to 389
