    Default IPv6 Only - doesn't quite work... (breaks at LDAP)

    Ok so I have a brand new machine with debian Lenny (5.0.2) and downloaded ZCS Community Edition.

    My Network config is this:

    # ip a ls
    1: lo:  mtu 16436 qdisc noqueue state UNKNOWN 
        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
        inet scope host lo
        inet6 ::1/128 scope host 
           valid_lft forever preferred_lft forever
    2: eth0:  mtu 1500 qdisc pfifo_fast state DOWN qlen 1000
        link/ether 52:54:00:29:c1:ff brd ff:ff:ff:ff:ff:ff
    3: eth1:  mtu 1500 qdisc pfifo_fast state UP qlen 1000
        link/ether 52:54:00:65:80:a8 brd ff:ff:ff:ff:ff:ff
        inet6 2a01:198:483:0:5054:ff:fe65:80a8/64 scope global dynamic 
           valid_lft 2591800sec preferred_lft 604600sec
        inet6 fe80::5054:ff:fe65:80a8/64 scope link 
           valid_lft forever preferred_lft forever
    # cat /etc/hosts	localhost
    2a01:198:483:0:5054:ff:fe65:80a8 zimbra6.localdomain zimbra6
    # The following lines are desirable for IPv6 capable hosts
    ::1     localhost ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters
    ff02::3 ip6-allhosts

    meaning I'm trying to get it running with only IPv6 connectivity. After installing the dependencies and starting the script it breaks at the LDAP step:

    *** CONFIGURATION COMPLETE - press 'a' to apply
    Select from menu, or press 'a' to apply config (? - help) a

    I have a feeling that slapd is choking on the v6 address as /var/log/syslog tells me:

    Sep  9 16:10:08 zimbra6 slapd[16722]: @(#) $OpenLDAP: slapd 2.4.17 (Aug  2 2009 17:09:01) $
    Sep  9 16:10:48 zimbra6 slapd[16722]: daemon: getaddrinfo() failed: Name or service not known
    Sep  9 16:10:48 zimbra6 slapd[16722]: slapd stopped.
    Sep  9 16:10:48 zimbra6 slapd[16722]: connections_destroy: nothing to destroy.
    according to openldap 2.4 should be v6 capable

    any hints?

    To answer my own question:

    # pgrep -lf slap
    18393 /opt/zimbra/openldap/sbin/slapd -l LOCAL0 -4 -u zimbra -h ldap://zimbra6.localdomain:389 ldapi:/// -F /opt/zimbra/data/ldap/config
    Why is slapd started with "-4" to make it listen on IPv4 only? Is there a reason for that?

    EDIT: I'm asking this because I specifically do NOT want public IPv4 addresses
