[horde] Stumped on LDAP Auth

I have to admit, I'm newb at OpenLDAP. I've been doing Microsoft AD
for years, but this is very different.

Short version: When I try to login, I get "Empty Result" and nothing else.

Long version: I followed the NewLDAPHowTo wiki pretty closely, but
there's few things that we're spoon fed enough, I guess. Here's the
auth and group snippets from my conf.php:

$conf['auth']['admins'] = array('admin');
$conf['auth']['checkip'] = true;
$conf['auth']['checkbrowser'] = true;
$conf['auth']['alternate_login'] = false;
$conf['auth']['redirect_on_logout'] = false;
$conf['auth']['params']['hostspec'] = 'localhost';
$conf['auth']['params']['basedn'] = 'dc=company,dc=local';
$conf['auth']['params']['binddn'] =
'uid=admin,ou=users,ou=horde,dc=company,dc=local';
$conf['auth']['params']['password'] = 'hldappw';
$conf['auth']['params']['version'] = '3';
$conf['auth']['params']['ad'] = false;
$conf['auth']['params']['uid'] = 'uid';
$conf['auth']['params']['encryption'] = 'ssha';
$conf['auth']['params']['newuser_objectclass'] =
array('shadowAccount', 'inetOrgPerson');
$conf['auth']['params']['objectclass'] = array('shadowaccount',
'inetorgperson', 'simpleSecurityObject');
$conf['auth']['params']['filter_type'] = 'objectclass';
$conf['auth']['params']['password_expiration'] = 'no';
$conf['auth']['driver'] = 'ldap';

$conf['group']['params']['hostspec'] = 'localhost';
$conf['group']['params']['basedn'] = 'dc=company,dc=local';
$conf['group']['params']['binddn'] =
'uid=admin,ou=users,ou=horde,dc=company,dc=local';
$conf['group']['params']['password'] = 'hldappw';
$conf['group']['params']['version'] = '3';
$conf['group']['params']['gid'] = 'cn';
$conf['group']['params']['memberuid'] = 'memberUid';
$conf['group']['params']['attrisdn'] = false;
$conf['group']['params']['newgroup_objectclass'] = array('posixGroup',
'hordeGroup');
$conf['group']['params']['objectclass'] = array('posixGroup');
$conf['group']['params']['filter_type'] = 'objectclass';
$conf['group']['driver'] = 'ldap';
$conf['group']['cache'] = false;

Here's my very basic LDAP tree:
dc=company,dc=local (5)
--cn=root
--ou=DSA (1)
-----cn=horde
--ou=groups
--ou=horde (2)
-----ou=groups
-----ou=users (1)
---------uid=admin
--ou=people

I've tried logging in using the root user, the horde user, and the
admin user and their respective passwords but get the same result. I
even tried using the full DN for each user just in case. I've also
tried using cn=root,dc=company,dc=local as the "binddn" in case it was
a permissions issue, and that didn't work either.

One other thing I might mention is whenever I try to include the
horde.schema into my slapd.conf file, it won't start. I don't know if
that's required for authentication or just preference storage, but
whatever.

Thank you so much for your help!
