No need to remove this, just use it to set the ipv4 settings to manual
and enter your static settings.

This is because you use .local for your realm name

Fairly easy to compile and install bind9 yourself on debian:
Install all required dependencies
install bind9 with apt-get
remove bind9 with apt-get
this will leave you with all the required configuration files!
Get the bind tarball from ftp://ftp.isc.org/isc
Untar said tarball
Now compile it using this configure line:
./configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --sysconfdir=/etc/bind --localstatedir=/var
--enable-threads --enable-largefile --with-libtool --enable-shared
--enable-static --with-openssl=/usr --with-gssapi=/usr
--with-dlopen=yes --with-gnu-ld --enable-ipv6
CFLAGS='-fno-strict-aliasing -DDIG_SIGCHASE -O2'

Unless you want to live on the bleeding edge and maybe end up with
something that may not work, then yes use the latest tarball.

There is a good reason why this is not documented in the wiki, the
keytab that you refer to, should be created automatically when you

Sorry, I cannot comment on sssd, except to say that it works for me.
