FreeIPA has it’s own password module that “intercepts” the DS password change operation, and does extra work. It’s quite complex and hard to get ones head around.

So DS still hashes based on configuration (Should be PBKDF2 on 1.4.x, SSHA512 on 1.3.x), but extra hashes + krb are added/changed in the process, including ipaNTHash if the adtrust prep was run.

Yes, this is a better solution than trying to sync hashes. IIRC googles hash format is really weak that they accept for sync, so external portal like this is better.
