samba - Jan 2016 - Provisioning AD DC, MS-AD_Schema_2K8_R2_Attributes.txt Not found

Hi,

I just removed the Canonical repo's Samba and compiled the latest version
by running './configure', 'make', and 'sudo make
install'.  Everything went
fine with that process, however, I've run into a snag when attempting to
provision Samba as an ADC.

I'm getting the following error:

ERROR(<type 'exceptions.IOError'>): uncaught exception - [Errno 2]
No such
file or directory:

__parse_schema_file
    f = open(filename, "rU")


I have the required file:

How do I fix this?

Thanks,

My guess is you have some mix of packaged and from-source builds.

I'll take your guess Andrew and raise it with, the OP probably hasn't 
set the path to his compiled version i.e.

     echo "PATH=/usr/local/samba/bin:/usr/local/samba/sbin:\$PATH"
>
/etc/profile.d/samba4.sh
     export PATH=/usr/local/samba/bin:/usr/local/samba/sbin:$PATH

he seems to be still trying to use his original Samba.

I ran apt-get remove --purge samba.

What is the proper procedure to remove it?

I've moved past this particular error by copying the files to that location
but have hit a new snag, how do I completely wipe out all traces of the old
packages?

You don't actually have to remove the distro packages, you just have to 
ensure that the compiled binaries etc are found first, see my earlier post.

If you want to use winbind in /etc/nsswitch.conf, you will need to 
delete the libnss_winbind files and create new links, see here for info:

https://wiki.samba.org/index.php/Libnss_winbind_links

Wanted to update this thread and mark it as SOLVED, hopefully my notes will
be useful to another user down the road.

My issue was indeed not having the new version of samba in my path, however
I had to add it in two locations other than /etc/profile.d

Appending ":/usr/local/samba/bin:/usr/local/samba/sbin" to the PATH
declaration in /etc/environment and /etc/sudoers allowed me to execute
samba-tool as sudo and provision my domain without errors.

After the install we will add the path to the *bin* and *sbin* directory
of

I then had to add an init script to /etc/init.d to start samba at boot and
now I'm good to go.

Thanks for the hints... now to figure out samba_backup

Thought so, your problem was that you ran 'samba-tool' with sudo.

You do not actually have to do this, all the files in samba/bin and 
samba/sbin are executable by *anybody*, just don't use sudo and 
definitely don't give anybody an admin password that you do not trust.

I am afraid you are wrong again :-)     If you are going to add them, 
add them at the start, this way they will be found *before* any other 
earlier versions.

There was probably already one there, it ust wanted the paths changing.

backing up samba is easy, restoring it is another thing altogether :-)
