Hi William, good news is, Dogtag, DNS and NTP are all optional
components, you can install a FreeIPa server withouth the CA and
without DNS. NTP is installed by default, but it is very easy to
diasable it if you want.

Kerberos is a core feature and cannot be disabled, but I thing you
figured that out already.

We have some plans to split the rpm packaging so that DNS and CA
components can be split into separate subpackages, however we are not
there yet, as some restructuring of the installer and framework will
need to happen to be able to completely omit some of the pieces.

We are well aware of the shortcomings of the documentation,
unfortunately our upstream documentation effort died due to not enough
participation, so in the future the most up to date docs will be RHEL
docs. We'll add pointers to them in freeipa.org pages once we are happy
enough with them.

On the testing side we are adding a lot of tests upstream that should
help improving test coverage and feature regressions, any help there is
welcome.

We always welcome feedback and help with the project, whether it is
code, or additional HOWTOs documentation or even just specific bugs and
RFEs that point out specific issues or areas where we can do better. Of
course our resources are limited so we'll prioritize what is most
requested, sometimes at the expenses of features we'd really like to
see but have no way to fund development for in the short term.

HTH,
Simo.
