The 2 things that I have found that I need to set outside of /usr/local/samba
are the $PATH and 2 symlinks for winbind. Both of these are documented on the
wiki (Thank you). If you use some type of configuration management such as ansible to
build the DCs you do not even have to think about setting these. Other than
that I have not needed to do anything else for a DC. For a file server I use
the distro supplied packages.

I do not know about the gvfs stuff. Since I only build dedicated DCs.

RHEL has always been behind as far as an AD DC is concerned because of the
MIT BS.

Having read this list for the last couple of years, I am starting to wonder
why people are making this all so hard. I understand that pre-built packages are
most desirable. I am a firm believer of that but in the case of a samba AD DC 
building rpms seems like a lot of extra work for little return.

If I did not have something like ansible to allow me to make the builds repeatable
and automated I might think differently but this works for me. :-)

Rowland, any chance of getting
https://wiki.samba.org/index.php/Package_Dependencies_Required_to_Build_Samba#Red_Hat_Enterprise_Linux_7_.2F_CentOS_7_.2F_Scientific_Linux_7
updated to reflect the package differences required for 4.10?

I simply enabled the epel-repository and substituted python3x-devel for
python-devel and added python3x-dns.

The python3x-dns package was not obvious but without it the build would succeed
but the samba-tool dns module would not work.

I kinda thought the configure script would complain if I was missing some of
the required python3 bits but it did not.

Is this a bug in the configure script or is this expected?
