Forum OpenACS Q&A: Response to Advice to ACS newbie wanting to do the problem sets, learn ACS

If you are concerned about security there is good book that guides you through how to set up an intranet using secured services (Apache-SSL, PostgreSQL), etc with Red Hat 6.2. The new version of this book is written for version 7.1/7.2 but they only released the book under GPL licence only after it has been for purchase for a while (hope that time will come soon :)). Hope this link helps
