If one has a back-mdb database, some searches on the indexed attr of "cn" fail. 
I do not see this issue with an identically configured back-hdb install.

cn is explicitly indexed in my db:
olcDbIndex: cn pres,eq,sub

This works:

zimbra@zre-ldap002:~$ ldapsearch -LLL -x -H ldapi:/// -D cn=config -w zimbra -b
"cn=config,cn=zimbra" -s base createTimeStamp cn
dn: cn=config,cn=zimbra
cn: config
createTimestamp: 20120217022019Z

However, the following searches all fail:

ldapsearch -LLL -x -H ldapi:/// -D cn=config -w zimbra -b "cn=zimbra" -s sub
cn=config cn

ldapsearch -LLL -x -H ldapi:/// -D cn=config -w zimbra -b "" -s sub cn=config
cn

ldapsearch -LLL -x -H ldapi:/// -D cn=config -w zimbra cn=config

ldapsearch -LLL -x -H ldapi:/// -D cn=config -w zimbra cn=zimbra

ldapsearch -LLL -x -H ldapi:/// -D cn=config -w zimbra "(cn=zimbra)"

However, the following searches work:

ldapsearch -LLL -x -H ldapi:/// -D cn=config -w zimbra
"(cn=zre-ldap003.eng.vmware.com)" cn
dn: cn=zre-ldap003.eng.vmware.com,cn=servers,cn=zimbra
cn: zre-ldap003.eng.vmware.com

zimbra@zre-ldap002:~/data/ldap/config/cn=config$ ldapsearch -LLL -x -H ldapi:///
-D cn=config -w zimbra -b "cn=zimbra" "(cn=zre-ldap003.eng.vmware.com)" cn
dn: cn=zre-ldap003.eng.vmware.com,cn=servers,cn=zimbra
cn: zre-ldap003.eng.vmware.com

Running "slapindex" does not fix the issue.
