Samba4 BDC

Kerberos

• make backup of kerberos conf

cp /etc/krb5.conf /etc/krb5.bak

• add realm to kerberos file /etc/krb5.conf

cp /usr/local/samba/share/setup/krb5.conf /etc/krb5.conf

• change ${REALM} variable to your realm
• test that you can kinit

kinit administrator

• type password then klist to check if you have ticket

klsit

Join DC to domain

• if kerberos is working check that you can see the PDC dns entries
• then join DC to domain

samba-tool domain join example.edu DC -Uadministrator --realm=example.edu

• should end with

Joined domain EXAMPLE (SID ...) as a DC

Transfer Roles

• DNS entries must ne setup before you can transfer roles, samba must be running (check log before for any errors)

*see who has what roles
samba-tool fsmo show

• transfer them all(can also transfer individual roles)

samba-tool fsmo transfer --role=all

nssswitch

• enumerate users in getent passwd
• link winbind so nsswitch can see

ln -s  /usr/local/samba/lib/libnss_winbind.so.2  /lib64/libnss_winbind.so
ln  -s /lib64/libnss_winbind.so  /lib64/libnss_winbind.so.2

• check that it is linked

ldconfig -v | grep winbind

• edit /etc/nssswitch to contain

passwd:     files winbind
shadow:     files
group:      files winbind
