All the headers are now listed in _SOURCES variable.
It seems weird but this is what GNU Automake manual suggests in section
9.2 Header files:
Headers used by programs or convenience libraries are not installed.
The noinst_HEADERS variable can be used for such headers.
However when the header actually belongs to a single convenience library
or program, we recommend listing it in the program’s or library’s
_SOURCES variable (see Program Sources) instead of in noinst_HEADERS.
This is clearer for the Makefile.am reader.
noinst_HEADERS would be the right variable to use in a directory containing
only headers and no associated library or program.

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.

This new extended operation allow to create new keys or retrieve
existing ones. The new set of keys is returned as a ASN.1 structure
similar to the one that is passed in by the 'set keytab' extended
operation.
Access to the operation is regulated through a new special ACI that
allows 'retrieval' only if the user has access to an attribute named
ipaProtectedOperation postfixed by the subtypes 'read_keys' and
'write_keys' to distinguish between creation and retrieval operation.
For example for allowing retrieval by a specific user the following ACI
is set on cn=accounts:
(targetattr="ipaProtectedOperation;read_keys") ...
... userattr=ipaAllowedToPerform;read_keys#USERDN)
This ACI matches only if the service object hosts a new attribute named
ipaAllowedToPerform that holds the DN of the user attempting the
operation.

There is a special mode to set the ipaNTHash attribute if a RC4 Kerberos

but no other password attribute. This means that the current check on
the userPassword attribute is too strict for this case and leads to a
failure of the whole operation.
With this patch the access right on ipaNTHash are checked if no other
password operations are requested.
