This page is for describing the migration and current setup of the Active Directory domain at UCC.

The primary DNS server for domain is molmol.ucc.gu.uwa.edu.au.

Upgrade/Setup Process

The Active Directory domain at UCC will be ad.ucc.gu.uwa.edu.au.

The Active Directory test domain at UCC is adtest.ucc.gu.uwa.edu.au. The primary server for the test domain is samson.ucc.gu.uwa.edu.au.

ad{,test}.ucc.gu.uwa.edu.au is delegated using separate zones in Mooneye's /etc/bind/named.conf.local

Samson's test domain is set up by:

• apt-get install samba winbind chrony

• Disable the systemd units for the non-DC setup & default configuration:

systemctl stop smbd
systemctl stop nmbd
systemctl stop winbind
systemctl disable smbd
systemctl disable nmbd
systemctl disable winbind
rm /etc/samba/smb.conf

• scp root@molmol:/usr/local/etc/smb4.conf /opt/smb.conf.pdc

• scp root@molmol:/var/db/samba4/\*.tdb /opt/samba-db/

• scp root@molmol:/var/db/samba4/private/\*.tdb /opt/samba-db/

• Change "UCCDOMAIN" to "UCCDOMAYNE" and Mussel's hostname to an IP address in /opt/smb.conf.pdc

• Comment out the ZFS-specific entries in /opt/smb.conf.pdc.

• samba-tool domain classicupgrade --use-xattrs=yes --realm adtest.ucc.gu.uwa.edu.au --dbdir=/opt/samba-db --dns-backend=SAMBA_INTERNAL --verbose /opt/smb.conf.pdc

Windows systems

Just join them to the domain. Doesn't look like you need to create a machine account before joining?

Linux systems

Based on the instructions from https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Domain_Member and https://wiki.samba.org/index.php/Authenticating_Domain_Users_Using_PAM Adding a Linux system is as follows:

ensure the system is configured according to the standard SOE edit /etc/krb5.conf with:

   [libdefaults]
        default_realm = adtest.ucc.gu.uwa.edu.au
        dns_lookup_realm = false
        dns_lookup_kdc = true

Change /etc/samba/smb.conf:

[global]
# Configure the domain infomation
        security = ads
        realm = adtest.ucc.gu.uwa.edu.au
        workgroup = UCCDOMAYNE

# use winbind to map users and groups
        winbind enum users = yes
        winbind enum groups = yes
        winbind use default domain = yes
        kerberos method = secrets and keytab

#Config gid/sid mapping based on AD attributes
        winbind nss info = rfc3207

        idmap config * : backend = tdb
        idmap config * : range = 13000-17999
        
        #idmap config for UCCDOMAYNE
        idmap config UCCDOMAYNE:backend = ad
        idmap config UCCDOMAYNE:schema_mode = rfc2307
        idmap config UCCDOMAYNE:range = 1-999999
        idmap config SAMDOM:unix_primary_group = yes

* Join the domain with: net ads join -U <username>.

* configure pam

* configure nssswitch.conf

* start the services:

winbindd
nmbd
smbd

* test the to make sure it works with: getent group

* run pam-auth-update and enable the winbind module.

dispense no longer has to back onto LDAP, so once Merlo is converted then things should just work
