Additional schema is unlikely to cause issues if it does not conflict
with standard schema. We also tend to prefix all the
attributes/objectlasses we create for FreeIPA so name clashes are
If it is custom schema I suggest you to prefix names appropriately too,
so you have your own 'namespace'.

As for placement I suggest you put this data in a separate container
from standard FreeIPA stuff for new objects.

In the base DN create a container named something like your company name
or ticker: cn=ACME,<suffix> and put all your customized entries there.

Attaching additional data to users is not a big deal for custom schema.
If it is not custom schema but standard schema not currently used by
FreeIPA I would be a little bit more careful as a following version of
FreeIPA might conceivably start using those attributes, and there is
generally enough space to use them in a sort of 'incompatible' way.

But don't let that stop you if you really need it.
