Description

In some rare circumstances, object class top is is missing from the search result, although the object classes are requested.
Here is an example.

Import an entry like this:

dn: cn=Heather Nova,dc=example,dc=com
objectclass: top
objectclass: person
cn: Heather Nova
sn: Nova
description: a singer-songwriter and poet based in Bermuda

i.e.

$ ldapmodify -h localhost -p 389 -D "uid=admin,ou=system" -w ***** -a -f heather.ldif
adding new entry cn=Heather Nova,dc=example,dc=com
$

Then perform a search request with the following parameters

$ ldapsearch -h localhost -p 389 -D "uid=admin,ou=system" -w ***** -b "cn=Heather Nova,dc=example,dc=com" -s base "(objectclass=*)" objectclass
version: 1
dn: cn=Heather Nova,dc=example,dc=com
objectclass: person
$

Object class "top" is missing from the search result! This is not the case, if abjectClass is not requested by parameter:

$ ldapsearch -h localhost -p 389 -D "uid=admin,ou=system" -w ***** -b "cn=Heather Nova,dc=example,dc=com" -s base "(objectclass=*)"
version: 1
dn: cn=Heather Nova,dc=example,dc=com
description: a singer-songwriter and poet based in Bermuda
objectclass: person
objectclass: top
sn: Nova
cn: Heather Nova
$

Note: Afterwards (after the last search call), the object class "top" is returned with the first request, as well (cache?):

$ ldapsearch -h localhost -p 389 -D "uid=admin,ou=system" -w ***** -b "cn=Heather Nova,dc=example,dc=com" -s base "(objectclass=*)" objectclass
version: 1
dn: cn=Heather Nova,dc=example,dc=com
objectclass: person
objectclass: top
$

I have created a JUnit test with JNDI, which demonstrates the defect. I'll attach it to this issue soon.
