A managed host may handle several ipaReplTopoManagedSuffix.
Removing (from the topology) such host, loops over the replicated
suffixes array to retrieve, in the hosts list, the host record and delete it.
The problem is that a variable used to manage a hosts list is not reset
when looking at the next suffix. That will messup the lists, keeping
freed elements in the lists.
The fix is to reset the variable inside the replicated suffix loop

Before this patch, if either password or password+otp were permitted,

Before this patch, if the user was configured for either OTP or password
it was possible to do a 1FA authentication through ipa-otpd. Because this
correctly respected the configuration, it is not a security error.
However, once we begin to insert authentication indicators into the
Kerberos tickets, we cannot allow 1FA authentications through this
code path. Otherwise the ticket would contain a 2FA indicator when
only 1FA was actually performed.
To solve this problem, we have ipa-otpd send a critical control during
the bind operation which informs the LDAP server that it *MUST* validate
an OTP token for authentication to be successful. Next, we implement
support for this control in the ipa-pwd-extop plugin. The end result is
that the bind operation will always fail if the control is present and
no OTP is validated.

Previously we published timestamps of planned state changes in LDAP.
This led to situations where state transition in OpenDNSSEC was blocked
by an additional condition (or unavailability of OpenDNSSEC) but BIND
actually did the transition as planned.
Additionally key state mapping was incorrect for KSK so sometimes KSK
was not used for signing when it should.
Example (for code without this fix):
- Add a zone and let OpenDNSSEC to generate keys.
- Wait until keys are in state "published" and next state is "inactive".
- Shutdown OpenDNSSEC or break replication from DNSSEC key master.
- See that keys on DNS replicas will transition to state "inactive" even
though it should not happen because OpenDNSSEC is not available
(i.e. new keys may not be available).
- End result is that affected zone will not be signed anymore, even
though it should stay signed with the old keys.

for lists there's the list() constructor.
When iterating through the entire dict, without modifying the dict,
the difference between Python 2's items() and iteritems() is

FreeIPA also uses this principal's credentials to retrieve domain topology.
The access to the keys of the principal should be well-protected. We only
