We now allow this to be via the ENCTYPE_AES256_CTS_HMAC_SHA1_96 hash instead
which allows us to decouple Samba from the unsalted NT hash for
organisations that are willing to take this step (for user accounts).
(History checking is limited to the last three passwords only, as
ntPwdHistory is limited to NT hash values, and the PrimaryKerberosCtr4
package only stores three sets of keys.)
Since we don't store a salt per-key, but only a single salt, the check
will fail for a previous password if the account was renamed prior to a
newer password being set.

Over the last month I got more and more reports,
that it's not possible to use a custom Samba version
on systems with sssd being installed, which depends on some
specific samba libraries installed in the system.
One major problem is that the custom libnss_winbind.so.2
depends on the libreplace-samba4.so of the custom build
and also injects an RPATH into the running process.
When sssd uses any nss library call it will get this,
when it then tries to load some of its plugins via dlopen(),
e.g.
ldd /usr/lib64/sssd/libsss_ad.so| grep samba
libsamba-util.so.0 => /lib64/libsamba-util.so.0
libreplace-samba4.so => /usr/lib64/samba/libreplace-samba4.so
libsamba-security-samba4.so => /usr/lib64/samba/libsamba-security-samba4.so
libsamba-errors.so.1 => /lib64/libsamba-errors.so.1
libsamba-debug-samba4.so => /usr/lib64/samba/libsamba-debug-samba4.so
libgenrand-samba4.so => /usr/lib64/samba/libgenrand-samba4.so
libsocket-blocking-samba4.so => /usr/lib64/samba/libsocket-blocking-samba4.so
libtime-basic-samba4.so => /usr/lib64/samba/libtime-basic-samba4.so
libsys-rw-samba4.so => /usr/lib64/samba/libsys-rw-samba4.so
libiov-buf-samba4.so => /usr/lib64/samba/libiov-buf-samba4.so
When that loads dlopen() will fail as a soname libreplace-samba4.so is
already loaded, but the symbol version within the other one don't match, as the
contain the exact version, e.g. replace_dummy@@SAMBA_4.13.3.
This is just an example and similar things can happen in all situations
where we provide libraries, which are potentially injected into every
process of the running system. These should only depend on libc.so and
related basic system libraries in order to avoid the problem.
We have the following libraries, which are in the that category:
- libnss_winbind.so.2
- libnss_wins.so.2
- pam_winbind.so
- winbind_krb5_locator.so
- async_dns_krb5_locator.so
The rules of library loading are really complex and symbol versioning
is not enough to solve it, only the combination of unique soname and
unique symbol version suffix seem to solve the problem, but injecting
an RPATH is still a problem.
In order to solve the problem I experimented with adding SAMBA_SUBSYSTEM()
definitions with 'hide_symbols=True' in order to do some static linking
of selected components, e.g.
bld.SAMBA_SUBSYSTEM('replace-hidden',
source=REPLACE_SOURCE,
group='base_libraries',
hide_symbols=True,
deps='dl attr' + extra_libs)
It's relatively simple to get to the point where the following are
completely static:
- libnss_winbind.so.2
- libnss_wins.so.2
- pam_winbind.so
- winbind_krb5_locator.so
But 'async_dns_krb5_locator.so' links in almost everything!
It seems we install the krb5 plugins into our own $MODULESDIR/krb5/,
so it may not be so critical, as long it's the admin who created
the desired symlinks into the location the kerberos libraries search
for plugins. Note the at least the locator plugins are always loaded
without any configuration, every .so in a special path are loaded with dlopen().
This is done by every application using kerberos, so we load a lot of samba libraries
into them.
Packagers should not put async_dns_krb5_locator.so (nor a symlink) into
the path that's reachable by libkrb5.so.
As a longterm solution we may want to change async_dns_krb5_locator.so
to use a helper process with posix_spawn() instead of doing everything
within the process.
Note I added hiden_symbols=True to the nss modules for Linux and
FreeBSD only, because these are the only platforms I'm able to test
on. We most likely should do the same on other platforms, but some
with access to the platform should provide a tested patch.
In order to avoid manual definitions of SAMBA_SUBSYSTEMS() with
'-hidden', I added the 'provide_builtin_linking=True' option,
as the logic is very similar to what we already have with the
'--builtin-libraries=BUILTIN_LIBRARIES' configure option.
SAMBA_PLUGIN() is used in order to use SAMBA_LIBRARY() in order
to make it more strict that these plugins can't be used as
normal depedency by other subsystems and libraries.
While being there it was easy enough to make libwbclient.so
also standalone without dependecies to other samba libraries.

The 'ktest' environment was/is designed to test kerberos in an active
directory member setup. It was created at a time we wanted to test
smbd/winbindd with kerberos without having the source4 ad dc available.
This still applies to testing the build with system krb5 libraries
but without relying on a running ad dc.
As a domain member setup requires a running winbindd, we should test it
that way, in order to reflect a valid setup.
As a side effect it provides a way to demonstrate that we can accept
smb connections authenticated via kerberos, but no connection to
a domain controller! In order get this working offline, we need an
idmap backend with ID_TYPE_BOTH support, so we use 'autorid', which
should be the default choice.
