Demonstrate your problem using the FreeIPA demo instance, please.

Compat tree is not writable, thus you cannot delete anything from it
directly. You only can delete the original entry to cause removal of a
compat entry.

Show how it is not removed with step by step ldapsearch/ipa CLI
operations against our demo instance, please.
