Link to wrong guide for Out of the Box Elytron

Book: How to Configure Server Security
Revision: 6bff93b8
Section: 2.1.2.7. Using the Out of the Box Elytron Components

Issue description:
In section 2.1.2.7. Using the Out of the Box Elytron Components there is twice something like "... Out of the Box section of the Security Architecture guide". However provided link from "Out of the Box" does not link "Security Architecture guide", but is uses "How to Configure Server Security".

Suggestions for improvement:
Change link from "How to Configure Server Security" to "Security Architecture" for "Out of the Box" in section 2.1.2.7. Using the Out of the Box Elytron Components.
