I am in the process of getting samba working again with Activer
Directory. Recently our IT department
upgraded their windows server to 2008.
I am following the approach described here:
http://www.surlyjake.com/linux/samba/join-debian-lenny-to-active-directory-using-samba/
I am able to get kerberos to issue a ticket, but where I am running
into a wall is with the net join ads part... It appears to work in that
setting the correct dn and using the username given to me by Jim for
binding to the windows server passes back a message that looks OK:
nanoelecfs:/home/joel# net ads dn 'DC=fs,DC=uml,DC=edu' join -U XXXXX
Enter XXXXX's password:
Got 1 replies
But if I try to test this by issuing the net ads testjoin command, I am
always asked this (highlighted in red):
nanoelecfs:/home/joel# net ads testjoin
Enter nanoelec...@fs.uml.edu's password:
[2010/01/25 22:36:17, 0] libads/kerberos.c:ads_kinit_password(356)
kerberos_kinit_password nanoelec...@fs.uml.edu failed:
Preauthentication failed
Join to domain is not valid: Logon failure
There is no such account, as kerberos is happy to indicate. This is odd
because I do not recall getting this
before the upgrade to 2008. NANOELECFS is the name of the linux box.
Trying wbinfo -t gives the following:
nanoelecfs:/home/joel# wbinfo -t
checking the trust secret via RPC calls failed
Could not check secret
I am running a Debian Lenny system with kernel version 2.6.26-2-amd64
I am running samba version 2:3.2.5
Thanks in advance!
