Ok, I am back again, trying to get sssd to control sudo, but failing.
I added the sudo active directory schema ldif to samba4 AD
then added this:
dn: OU=SUDOers,DC=example,DC=com
objectClass: top
objectClass: organizationalUnit
ou: SUDOers
dn: CN=linuxusers,OU=SUDOers,DC=example,DC=com
objectClass: top
objectClass: sudoRole
cn: linuxusers
sudoUser: %linuxusers
sudoHost: ALL
sudoCommand: ALL
On a Linux Mint client:
sudo apt-get install sudo-ldap
Edited /etc/sudo-ldap.conf
# TLS certificates (needed for GnuTLS)
TLS_CACERT /etc/ssl/certs/ca-certificates.crt
BASE DC=example,DC=com
URI
ldap://server.example.com
ssl=no
LDAP_VERSION 3
SUDOERS_BASE ou=SUDOers,DC=example,DC=com
SUDOERS_SEARCH_FILTER (&(objectClass=sudoRole))
BINDDN CN=Administrator,CN=Users,DC=example,DC=com
BINDPW xxxxxxxxxx
then edited /etc/nsswitch.conf and added
sudoers: files ldap
restarted sudo
then as a normal user, tried to run a command with sudo, this worked.
I then altered /etc/sssd/sssd.conf and added
services = nss, pam, autofs, sudo
[sudo]
ldap_sudo_search_base = OU=SUDOers,DC=example,DC=com
^^^^^^
This line should be in domain section and not "[sudo]"
I hope it helps.

altered /etc/nsswitch.conf
sudoers: files sss
restarted sssd
restarted sudo
tried to run the command with sudo again, this time it failed
having been bitten by the way autofs works, I went straight to the
way that sudo & sssd do the ldapsearch:
SUDO
(&(&(objectClass=sudoRole))(|(sudoUser=rowland)(sudoUser=%Domain
Users)(sudoUser=%#20513)(sudoUser=%vboxusers)(sudoUser=%linuxusers)(sudoUser=%#127)(sudoUser=%#21110)(sudoUser=ALL)))
SSSD
(&(objectClass=sudoRole)(|(!(sudoHost=*))(sudoHost=ALL)(sudoHost=ThinkPad)(sudoHost=ThinkPad.home.lan)(sudoHost=192.168.0.204)(sudoHost=192.168.0.0/24)(sudoHost=fe80::86a6:c8ff:fe3b:da7b)(sudoHost=fe80::/64)(sudoHost=+*)(|(sudoHost=*\\*)(sudoHost=*?*)(sudoHost=*\**)(sudoHost=*[*]*))))
sudo searches with objectClass=sudoRole & sudoUser attribute
sssd searches with objectClass=sudoRole & sudoHost attribute
Now I understand that the sssd search for the sudoHost attribute is
to ensure that only sudo rules for the host are downloaded, but it
doesn't actually seem to download any rules.
Is there anyway I can get the sssd search to include the sudoUser
attribute in the same way that the sudo ldap search does?
Or can anybody tell me where I am going wrong (again).
