hello all,

we are trying to setup a ldap server which uses the mysql as back-end instead of bdb backend.we have installed slapd and ldap-utils
 in debian-etch .we also have installed mylibodbc, mysql-client-5,mysql-server-5. we have established the mysql-ODBC connectivity and tested the connectivity using
isql.we have configured the slapd.conf file to connect mysql  and when we tried to add entries using ldapadd , we get the following err
    ldap_add: Server is unwilling to perform (53)
         additional info: operation not permitted within namingContext


 
this is the slapd.conf
file


# This is the main slapd configuration file. See slapd.conf(5) for more
# info on the configuration options.
