I suspect this is not going in the direction I'd envisioned.

The Plan was an AD PDC that used OpenLDAP.  That way: OpenLDAP data,
replicated to the mail server, could be used for sign-on there, too.

Somewhere somebody recently mentioned a single-sign-on doc.  I'll have
to hunt that down and take a look.

Thanks,
Jim

I haven't followed the original thread, so I don't know what was already
discussed there.


If you're talking about a PDC: Yes, you can use openLDAP as backend, as
you always could for a NT4 domains.


However you seem to talk about AD, so I think you wrongly mix up PDC
with DC. If you're talking about Active Directory, then you can't use
openLDAP as AD backend for Samba in it's current state. Nadya is working
on this, but it will still take some time, until this is finished. And I
can't say if and how replication between an AD openLDAP and a classic
one would work because it requires special stuff.

If interested, see Nadyas SambaXP talk from 2014:

I'm very confused. I have a Samba4 AD/DC which works great for Windows
Authentication with our Windows 7 workstations.

Now, I am trying to implement single-sign-on for our coming-soon Linux
workstations.
All web documentation I've so far found on this references OpenLDAP as the
server
and describes server-side commands such as kadmin and slapd-config to get things
set up on the server-side (e.g. https://help.ubuntu.com/community/SingleSignOn)
which don't exist on the Samba4 AD/DC.

Samaba4 apparently has it's own LDAP (Heimdal?) implementation.  Does this
mean
everything should "just work" with LDAP clients and I need do no
further
server-side configuration? Or does it mean, "sorry, you can't do LDAP
Authentication with Samba4."

Please clarify so I can make some decisions.

btw - the following command *does* work from a Linux client on the network:

ldapsearch -xLLL -H ldap://mail:389 -D
"cn=Administrator,CN=Users,dc=HPRS,dc=local" -W -b
"dc=HPRS,dc=local"

Hai Mark, 

Look here for a single sign on setup. 
Its not for linux clients, but you can learn / understand from it. 
Worth reading. 
https://community.zarafa.com/pg/blog/read/18332/zarafa-outlook-amp-webaccess-sso-with-samba4

Now, i dont have a linux workstation setup here, but you need to know is on the
ubuntu page and samba wiki.
As for the example, https://help.ubuntu.com/community/SingleSignOn tells.  
To put you in the correct direction. 

SSO KERBEROS AUTH 
1-4.1 skip. thats your addc. 
5. what you want. 
I suggest skip first, setup with mkhomedir in pam for the client and when that
works, setup the shared file system.

6.1 do 1. 2. 3. generate a keytab (on the DC) ( if you do a member server setup
on the client, skip 4. 5. 6.)
To create the keytab file, you can setup as a member server samba on the client,
which generates te keytab file or create one yourself on dc. Instruktions on the
wiki.

6.2 (client configuration ) 
apt-get install libnss-ldapd libsasl2-modules-gssapi-heimdal libpam-ccreds
optional libpam-krb5 libpam-ldap/libpam-ldapd, not sure about these ldap(d) 
do 1. 2. ( skip the tls for now, test without ) 

do optional 6.3. 

SSO LDAP AUTH
Optional 8. ( so not kerberos auth but sso by ldap auth ) 
apt-get install ldap-auth-client libpam-krb5 krb5-user libpam-foreground
libsasl2-modules-gssapi-heimdal

That should get you going.
