I actually spent the entire last day getting 'ad' backend to work.
Adding 'idmap config SAMDOM : backend = ad' and related lines in the
client's smb.conf results in `getent passwd` showing only local users. When
I remove the 'backend = ad' block from smb.conf, the `getent passwd`
starts showing the AD users as well, and I can also su and ssh (with password)
using those AD users. On a related note, as far as I can remember, I provided
the `use-rfc2307` parameter samba-tool when I provisioned the domain.
On the DC, I tried adding multiple groups with different --gid-number and also
tried adding users with various --uid-number and --gid-number. I followed the
instructions at [1] to add unix users and groups, but still the domain members
were unable to enumerate the domain users using `getent passwd`. After spending
the entire last day trying to troubleshoot/resolve the 'backend = ad'
issue, I settled on removing the 'ad' block from clients. Without the
'ad' block, things are looking better, with the only issue being that I
am unable to ssh using kerberos ticket; hence this mail.
