How to auto-start SSL-enabled Directory Server?

I have a defense customer requesting for their Sun Directory Server 5.2 to be SSL-enabled. 

However, once the Directory Server 5.2 is started, one has to manually key in the Token Pin:

$ /ds/slapd-DEF/start-slapd

Internal (Software) Token: 

He doesn't like this. He wants the Directory Service to be started automatically upon system reboots.

Well, there is a workaround:

1. $ cd /ds/alias

2. $ vi slapd-DEF-pin.txt

3. Enter the following into the text file:

    Internal (Software) Token:mysecretpassword

4. $ chmod 600 slapd-DEF-pin.txt

Restart the Directory Server. You're done!

PS: Make sure the naming convention of the PIN file is strictly adhered to: 

       [directory-instance]-pin.txt
