[horde] Can't Connect ActiveSync Android

[Kevin Smith]

I've been trying to set up my Android to connect to horde's activesync for
a couple days, now, and I can't seem to get it to work. I followed the WIKI
directions, here:

http://wiki.horde.org/ActiveSync

... but it makes no difference. Whenever I try to connect, the droid just
produces the 'unable to connect error' and there isn't much to go off of in
the log:

horde:80 192.168.15.104 - *** [22/Jun/2012:09:38:51 -0500] "OPTIONS
/Microsoft-Server-ActiveSync?Cmd=OPTIONS&User=***&DeviceId=validate&DeviceType=Android
HTTP/1.1" 302 828 "-" "Android/0.3"

I've replaced any user and other info with ***

$conf['activesync']['state']['params']['devicetable'] =
'horde_activesync_device';
$conf['activesync']['state']['params']['statetable'] =
'horde_activesync_state';
$conf['activesync']['state']['params']['maptable'] = 'horde_activesync_map';
$conf['activesync']['state']['params']['userstable'] =
'horde_activesync_device_users';
$conf['activesync']['logging']['path'] = '/var/log/horde/async.log';
$conf['activesync']['logging']['type'] = 'custom';
$conf['activesync']['ping']['heartbeatmin'] = 60;
$conf['activesync']['ping']['heartbeatmax'] = 2700;
$conf['activesync']['ping']['heartbeatdefault'] = 480;
$conf['activesync']['ping']['deviceping'] = true;
$conf['activesync']['ping']['waitinterval'] = 5;
$conf['activesync']['securitypolicies']['provisioning'] = false;
$conf['activesync']['enabled'] = true;

Does anyone have any experience or ideas to go off?
