Hi John,
There are only two realms I mentionned, LAB-LPP.LOCAL, and TEST-LPP.LOCAL. I am currently doing test with the latter, and indeed, pc-2003-test is the AD DC, so the KDC for TEST-LPP.LOCAL. The fdqn is also pc-2003-test.test-lpp.local.
'kinit <username>' works, [root@centos-test etc]# kinit pean Password for pean@TEST-LPP.LOCAL: [root@centos-test etc]# klist Ticket cache: FILE:/tmp/krb5cc_0 Default principal: pean@TEST-LPP.LOCAL

Kerberos 4 ticket cache: /tmp/tkt0 klist: You have no tickets cached
But nevertheless, it is asking for password when I issue the 'net ads join -U pean' command...
As you understood, my KDC server is a windows 2003 R2 Active directory server. I don't understand where it is looking for the credentials. I tried to create the krb5.keytab with ktpass on the windows server, and replace the one on the centos-test, but it does not work either. There is something, perhaps obvious, I miss. I also tried with 'validate = true' in /etc/krb5.conf, but with no success.
Have you tried with validate = false?
I'd expect that to work, but it's not what you want to be doing long term.
I found also that there is a 'krb5.conf.TEST-LPP' file in /var/lib/samba/smb_krb5, and this one is certainly used by samba (I replaced old version with samba3x, 3.5.4, and put 'kerberos method = secrets and keytab', instead of 'use kerberos keytab = true' that I used previously.
Does that config file conflict in any way with the system krb5.conf?
I don't know if you have, or anyone else, an idea ?
Ah, I'm using samba-common-3.0.33 for the join not samba3x, so there's possibly some subtle differences.
The join is reliant on /etc/samba/smb.conf (and presumably that krb5.conf.TEST-LPP) though, so you'd need to double check that's all correct.
