Patch looks great, thanks for including such detailed documentation.

But it's not applying to the current master:

Falling back to patching base and 3-way merge...
Auto-merging ipalib/plugins/service.py
CONFLICT (content): Merge conflict in ipalib/plugins/service.py
Auto-merging ipalib/x509.py
Failed to merge in the changes.
Patch failed at 0001 dogtag clean-up

Can you take a look?
