[kronolith] LDAP and Free/Busy

[gwen]

Hello, after much googling around I've found that others have asked
this question, but the answers are not turning up in those searches,
so I apologize for asking this again.  I would be happy to be pointed
at URLs which already answer this!  Anyway, here's the question:

I have installed Horde, Kronolith, Turba, etc, and have mostly
configured them to working order, including having them hooked into my
LDAP directory.  The one remaining problem I have now is getting the
free/busy time to work when I try to make a meeting.  Currently I am
getting this error:

Error retrieving free/busy information for [email address]: No
free/busy url found for [email address].

I do have the rfc2739.schema in my slapd and a typical entry looks
like this (in fact, the entry for above):

dn: uid=[user],ou=users,ou=horde,dc=wellspringworldwide,dc=com
objectClass: top
objectClass: shadowAccount
objectClass: inetOrgPerson
objectClass: wswPerson
objectClass: calEntry
sn: [user]
uid: [user]
userPassword:: [redacted]
mail: [email address]
cn: [full name]
imAccount: [im name]
calFBURL: http://horde.[domain]/kronolith/fb.php?u=[user]

I have this section in my horde/kronolith/prefs.php file:

$_prefs['search_sources'] = array(
    'value' => "localldap",
    'locked' => false,
    'shared' => false,
    'type' => 'implicit',
);

I am definitely calling up the ldap entries for Turba and when I
browse for attendees, so I am at this point uncertain of where to
proceed next to get the free/busy working.

Thank you for any help!
