[Samba] DRS stopped working after upgrade from debian Jessie to Stretch

Hello Samba team !

I'am in a very delicate situation. After an upgrade to debian Stretch
my DRS stopped working.

I have three DCs (fichdc, fichds01, fichds02), all Debian Stretch, all
with the same problem. Everything seems to be fine except DRS.
-> File shares works
-> DNS (with bind9 DLZ) works
-> "kinit administrator" works
-> "kinit -k FICHDC$" works
-> times synchronisation works
-> winbind works (with nsswitch)
-> domain controller "A" resolve
-> domain controller "objectGuid CNAME" record resolve
-> nfsv4 share works using sec=krb5

But when I try a DRS connection :

Have you ever had MIT krb5 installed, or is krb5kdc now running?

Samba doesn't use /etc/krb5.keytab, so this may be related to some
previous install (or may be related to how you are trying to use NFS).

Can you do this against the secrets.keytab in Samba's private/ dir?

You can reset the Samba machine account pw with
./source4/scripting/devel/chgtdcpass, but:
 - it wont be packaged so you will have to build Samba and tell it to
operate against the right paths
 - it shouldn't be needed, upgrades shouldn't break this, and
understanding the root cause would be better

Does 'samba-tool time -P' work?  It is any different with
'samba-tool
time -P -k no'?  (It seems you issue is related primarily to kerberos
and a keytab out of sync somehow).

As I mention above, this is the wrong keytab for a Samba DC.

I hope this helps, otherwise depending on the urgency you might need to
get some professional guidance.  It gets really stressful when then
network is down and we all know that can lead to mistakes.

Take care,

Hai, 

Just saying samba does not use /etc/krb5.keytab is not totaly correct. 

A lot of setups use the setting : dedicated keytab file = /etc/krb5.keytab 
Because systemd defaults point to /etc/krb5.keytab. 
>From his logs: Failed to find
FICHDC$@NET.LYC-GUILLAUME-FICHET.AC-GRENOBLE.FR(kvno 2) in keytab
FILE:/var/lib/samba/private/secrets.keytab (arcfour-hmac-md5)

And from his command (klist -k : Keytab name: FILE:/etc/krb5.keytab  ) the above
server is found.
Only the HOST/SPN entry is missing. 

This looks like that :
dedicated keytab file = /etc/krb5.keytab  
was in smb.conf but is gone now, or a symlink is replaced by a keytab file /etc
I suspect last one due to the upgrade. 

In this case, export the spn's again and check if host/spn and
NETBIOSNAME$@SPN exist.
use ktutil to import all entries from both keytab files and export the one you
need back.

I have checked, MIT kerberos is not installed, just the "krb5-user"
kerberos client package.

Yes you're right ! I need to understand the root of the problem as I
have some other DC to upgrade the same manner. And you're right
authentication with the private keytab does not work. But strangely it
works with /etc/krb5.keytab.

~# kinit -k -t /etc/krb5.keytab FICHDC$

--------------------------------
--------------------------------

I don't know what is "KVNO". But on the
"/etc/krb5.keytab" there is
"1" and "2" FICHDC$ principals entries. But on
"/var/lib/samba/private/secret.keytab" there is only "1".

And on the samba log file I have :

--------------------------------
GSS server Update(krb5)(1) Update failed:  Miscellaneous failure (see
text): Failed to find
FICHDC$@NET.LYC-GUILLAUME-FICHET.AC-GRENOBLE.FR(kvno 2) in keytab
FILE:/var/lib/samba/private/secrets.keytab (arcfour-hmac-md5)
--------------------------------

How "/var/lib/samba/private/secrets.keytab" is updated by samba ?

Thank you very much for the help !

Baptiste.

[Samba] DRS stopped working after upgrade from debian Jessie to Stretch

Hai Baptiste,

What you can try;
Type: 
ktutil (enter)
rkt /etc/krb5.keytab 
rkt /var/lib/samba/private/krb5.keytab 
list

Now check if you see, 
host/server.internal.domain.tld at REALM
host/server at REALM
(same (both) for nfs/.. at REALM) 

And 
NETBIOSNAME$@REALM

If you see all, you can write this back to a new file. 
wkt /etc/krb5.keytab.new1
And if needed you can also cleanup the keytab file before writing. 

Now choose, of 
dedicated keytab file = /etc/krb5.keytab 

Or use the samba default in /var/lib/samba/private/krb5.keytab 
In case of the samba default 
rm /etc/krb5.keytab 
ln -sf /usr/local/samba/private/krb5.conf /etc/krb5.conf

Some extra info on the keytab things.

I'm not disputing that the OP may have copied the keytab.  It still
won't change what path the Samba AD DC will use.

That won't change Samba to use /etc/krb5.keytab as an AD DC, nor should
it.  It might impact if NFS is in operation, but that is a secondary
task at this point. 

I'm being so blunt because:
 - Samba is internally inconsistent on this point
and
 - Samba folklore spreads like wildfire

Sorry,

Can you do this against the secrets.keytab in Samba's private/
dir?> You can reset the Samba machine account pw with

>Hello Andrew,

May I ask a few questions in regards to chgtdcpass.
Can this command be used to add newer enctypes on machines only having 
des and arcfour types?
Is it save to use this command on all ad-dc's in an productive environment?

Thanks in advance,

Hai Andrew,

No, your not blund. 
Its good you correct things like this, since english is not my native language, 
It can be a bit fuzzy to understand what i mean.

Im not disputing that also, but im "guessing" what is changed between
jessie and stretch.
I found one old "thingy" that the debian maint wont fix. 
Example: install winbind only, and you get missing ldb modules thing, not that
they are used but still.
( missing samba-dsdb-modules ) 

Somehow in how the system defaults work and how samba was setup, created the
problem at upgrade time.
I suspect, something like, during the upgrade of jessie to stretch, at samba
upgrade,
Samba is updateing the ADDB, now its unknown how long this takes and what
happens if you reboot the server
While the samba AD DB is still being updated.

Now, i dont run my nfs v4 on my DC's, so did not encounter this. 
Thanks, good to know.
