Issue

• Our customer defines "exg<Name>" attribute in the entries on his LDAP server. In addition, he uses "index" for "exg<Name>" attribute.

    slapd.conf
    ----------------------------
     index exg<Name> eq
    ----------------------------

    /var/lib/ldap/
    -----------------------
     exg<Name>.bdb
    -----------------------

• We add the same entries both on RHEL5.x(openldap-2.3.x) and on RHEL6.5(openldap-2.4.43) by LDIF file and we search entries with following search formula.
  *The minimum value of "exg<Name>" attribute's value is "19000101", and the maximum value of it is "20150121".

  # slapadd -f /etc/openldap/slapd.conf -l slapcat.log
  
  # ldapsearch -x -H ldap://127.0.0.1 -b 'ou=Users,ou=usermtn,dc=*******,dc=local' -D cn=Manager,dc=*******,dc=local -w ********* -LLL -s one '(exg<Name><=20150130)'
  

• We can search intended numbers of entries (38034) on openldap-2.3.x, on the other hand, in the case of openldap-2.4.43, the search result is 33115. Moreover, we delete index of "exg<Name>" attribute and re-search entries, we can search intended numbers of entries (38034) on openldap-2.4.43.

    Snipped from slapd.conf
    -----------------------------
     #index exg<Name> eq
    -----------------------------

    # rm /var/lib/ldap/exg<Name>.bdb
