Need a bit of help grokking logs

[Fran Fabrizio <fran@cis.uab.edu>]

I'm having trouble figuring out why a search isn't finding a record in 
my directory.  Here's the target record...

----------------------
# cars, ResourceGroups, ResourceObjects, OxObjects, cis.uab.edu
dn: 
resourceGroupName=cars,ou=ResourceGroups,ou=ResourceObjects,ou=OxObjects,dc=cis,dc=uab,dc=edu
objectClass: top
objectClass: OXResourceGroupObject
resourceGroupName: cars
resourceGroupAvailable: TRUE
resourceGroupMember: car1
-----------------------

(The Ox prefix indicates this is data for the Open-Xchange application.)
Now, turning on debug level 288, I see the following search hit the LDAP 
server when I try to search for this within OX...

-----------------------
begin get_filter
EQUALITY
end get_filter 0
conn=7 op=2 SRCH 
base="ou=ResourceGroups,ou=ResourceObjects,ou=OxObjects,dc=cis,dc=uab,dc=edu" 
scope=1 deref=3 filter="(objectClass=OXResourceGroupObject)"
conn=7 op=2 SRCH attr=resourceGroupName
=> bdb_filter_candidates
       EQUALITY
<= bdb_filter_candidates: id=0 first=0 last=0
=> bdb_filter_candidates
       AND
=> bdb_list_candidates 0xa0
=> bdb_filter_candidates
       EQUALITY
<= bdb_filter_candidates: id=3 first=39 last=65
<= bdb_list_candidates: id=3 first=39 last=65
<= bdb_filter_candidates: id=3 first=39 last=65
=> test_filter
   EQUALITY
<= test_filter 50
=> test_filter
   EQUALITY
<= test_filter 50
=> test_filter
   EQUALITY
<= test_filter 50
conn=7 op=2 SEARCH RESULT tag=101 err=0 nentries=0 text=
------------------------

So the search base, filter and attribute all appear to match the target 
record.  But I see that the nentries=0 which would tell me that no 
records were found and from the application layer it's definitely not 
returning any results.  I'm sure there are other clues within this 
output that I am missing.  Can anyone see why it might be failing to 
find the above record?

Thanks,
Fran

PS - Would be happy to find and read some documentation on parsing 
openldap logs in general - is there a good resource?
