The password is used to enroll the host it can't be used for anything else .
Enrolling the host means you provision a keytab for it.
AFAIU after succesful ipa-client-install : has_keytab=True,
because the password is always one time password used for enrollment

Now the question what are you trying to check.
I think you want to run a query on has_password=True, has_keytab=False
and modifyTimestamp is X time units in the past
This however would not be the exact test as the timestamp can be
adjusted due to different changes and does not reflect the creation of
the password.

I also opened a ticket to help with this situation in future:
