After the successful installing of openldap2.2.19, i executes the following
steps.
1. config the slapd.conf,set the acl as:
    access to dn.base="" by * read
    access to dn.base="cn=Subschema" by * read
    access to *  
	by users read
	by users write
2. start the slapd successfully
3. execute the command: 
     ldapsearch -x -b '' -s base '(objectclass=*)' namingContexts
   the output is :
     # extended LDIF
     #
     # LDAPv3
     # base <''> with scope base
     # filter: '(objectclass=*)'
     # requesting: namingContexts
     #
