Topic: making ldap to use slapd.d

Hi, by studying some guides in the internet I have changed the ldap to use slapd.d instead of using slapd.conf from then I am able to login and see ldap using phpldapadmin but i am unable to login to iredadmin and roundcube.

The procedure i have followed is.
1.stopping the ldap server /etc/init.d/slapd stop
2.Before bdb in slapd.conf i have wrote two lines of code
"rootdn "cn=Manager,cn=config"
rootpw pwd123"
3.slapcat -f slapd.conf -F slapd.d
4.chown -R openldap slapd.d/
   chgrp -R openldap slapd.d/
5.gedit /etc/default/slapd
"SLAPD_CONF=/etc/ldap/slapd.conf" is there default and I have changed it to "SLAPD_CONF=/etc/ldap/slapd.d"
6. /etc/init.d/slapd start (ldap server started successfully)..

Someone Please help me to resolve this issue, it will also helpful to many people in this forum..
