1. Provide a script where user (root) can modify the startup method to add the required '-h ldaps:///'
 
2. Create a trigger file within /etc/centrifydc/openldap which will allow the startup method to interrogate and choose '-h ldap:///' or '-h ldaps:///'
 
3. Correlation of (2), you may be able to reference a standalone configuration file to pick up all needed startup parameters.

Resolution:

As of Suite 2015.1, there is an added option in the startup script for ldapproxy: "STARTUP_OPTS". The service's startup script will source this option and pass the indicated startup options to slapd.

Example: To add the option for TLS support, the following method can be used:
 

Solaris:
# svccfg -s centrify-ldapproxy setprop 'slapd/STARTUP_OPTS=("-h" "ldaps:///")'
