**Note** Do not start Samba yet!
Active Directory Integration:
Obtain a kerberos ticket from your AD server by issuing the command:
kinit Administrator
You will then be asked for a password. Put in the Administrator password
for your Domain.
To verify the ticket was issued do the following:
klist
The results should appear as follows:
# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: Administrator at DOMAIN.COM
Valid starting Expires Service principal
11/03/04 14:26:23 11/04/04 00:26:22 krbtgt/DOMAIN.COM at DOMAIN.COM
renew until 11/04/04 14:26:23
Kerberos 4 ticket cache: /tmp/tkt0
klist: You have no tickets cached
Once you have obtained kerberos ticket you can join the computer to the
domain:
net ads join
Now start the Samba and Winbind:
/usr/local/samba/sbin/smbd -D
/usr/local/samba/sbin/nmbd -D
/usr/local/samba/sbin/winbindd
Winbind and Active Directory Authentication:
First you will need to copy the WINBIND file from where is was created when
you compiled Samba to /usr/lib/security:
cp /path/to/samba-3.0.8pre2/nsswitch/WINBIND /usr/lib/security
Next you will need to add a stanza to the file
/usr/lib/security/methods.cfg:
WINBIND:
program = /usr/lib/security/WINBIND
options = authonly
Finally you will need to edit /etc/security/users and make sure under the
default stanza that SYSTEM is set to WINBIND:
default:
admin = false
login = true
su = true
daemon = true
rlogin = true
sugroups = ALL
admgroups =
ttys = ALL
auth1 = SYSTEM
auth2 =
tpath = nosak
umask = 022
expires = 0
SYSTEM = "WINBIND"
logintimes =
pwdwarntime = 0
account_locked = false
loginretries = 0
histexpire = 0
histsize = 0
minage = 0
maxage = 0
maxexpired = -1
minalpha = 0
minother = 0
minlen = 0
mindiff = 0
maxrepeats = 8
dictionlist =
pwdchecks =
Test your authentication by issuing a telnet to the aix box and login using
your Active Directory credentials.
