question about openldap+mysql :(

[amybear96 <amybear96@sina.com>]

Hi all:
      I am trying to test my openlap-2.1.16 with backDB-mysql on 
redhat8.0 
      before i install the openldap ,i have made the "unixodbc+MySQL
+MyODBC" worked very well on my rh8.0 ,but i do not have access suite such as OpenLink DAS(i dont known what it is?)
      next,with the directives of openldap-2.1.16/servers/slapd/back-sql/docs/install ,i have run  testdb_create.sql,testdb_data.sql, and testdb_metadata.sql scripts 
and i can see the database and tables created in mysql server.
       then i add the fowllings to slapd.conf
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~` 
 database	sql
suffix		"o=sql,c=RU"
rootdn		"cn=root,o=sql,c=RU"
rootpw		secret
dbname		ldap_mysql
dbuser		root
dbpasswd	NULL
subtree_cond	"ldap_entries.dn LIKE CONCAT('%',?)"
insentry_query	"INSERT INTO ldap_entries (dn,oc_map_id,parent,keyval) VALUES               (?,?,?,?)"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
and set "odbc.ini" adding
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 [sql]
Description             = myodbc-openldap
Driver          = myodbc
Server          = localhost
Database                = ldap_mysql
Port            = 3306
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
then i try to run : /usr/local/libexec/slapd -d 5
and encounter connection problems as following
