The following commands are OPTIONAL.
They are for backing up CA and Server Certs in PK12 format,
exporting the CA Cert in ASCII format or DER format, and
importing the CA Cert into the Admin Server
---Start of OPTIONAL commands---

---End of OPTIONAL commands---
Modifying server SSL configurations.
NOTE: changes will be saved to config/dse.ldif when slapd is
shutdown
modifying entry cn=encryption,cn=config
ldap_modify: Type or value exists
deleting cn=RSA,cn=encryption,cn=config
adding new entry cn=RSA,cn=encryption,cn=config
Creating a pin.txt for auto-starting of slapd.
IMPORTANT NOTES:
1. How to check if SSL Configurations are done properly?
You may view config/dse.ldif after shutting down slapd
to verify all the required SSL configurations are there.
2. How to fix slapd startup issue due to mis-configuration of
SSL?
If for any reason slapd fails to start due to SSL issue,
you may edit config/dse.ldif after shutting down slapd
and revert back to non-SSL configs.
i.e. set nsSSL3: off, nsslapd-security: off
and then try to restart slapd.
