[Samba] Failed to find cifs/fs-share@dom.corp (kvno 109) in keytab
Ok, you did to much as far i can tell.
You want to see this: i'll show my output, then i is better to see what i
mean.
this is where you start with.
klist -ke |sort ( default member )
---- --------------------------------------------------------------------------
3 host/HOSTNAME1 at REALM.DOMAIN.TLD (aes128-cts-hmac-sha1-96)
3 host/HOSTNAME1 at REALM.DOMAIN.TLD (aes256-cts-hmac-sha1-96)
3 host/HOSTNAME1 at REALM.DOMAIN.TLD (arcfour-hmac)
3 host/HOSTNAME1 at REALM.DOMAIN.TLD (des-cbc-crc)
3 host/HOSTNAME1 at REALM.DOMAIN.TLD (des-cbc-md5)
3 host/hostname1.internal.domain.tld at REAL.DOMAIN.TLD
(aes128-cts-hmac-sha1-96)
3 host/hostname1.internal.domain.tld at REAL.DOMAIN.TLD
(aes256-cts-hmac-sha1-96)
3 host/hostname1.internal.domain.tld at REAL.DOMAIN.TLD (arcfour-hmac)
3 host/hostname1.internal.domain.tld at REAL.DOMAIN.TLD (des-cbc-crc)
3 host/hostname1.internal.domain.tld at REAL.DOMAIN.TLD (des-cbc-md5)
3 HOSTNAME1$@REALM.DOMAIN.TLD (aes128-cts-hmac-sha1-96)
3 HOSTNAME1$@REALM.DOMAIN.TLD (aes256-cts-hmac-sha1-96)
3 HOSTNAME1$@REALM.DOMAIN.TLD (arcfour-hmac)
3 HOSTNAME1$@REALM.DOMAIN.TLD (des-cbc-crc)
3 HOSTNAME1$@REALM.DOMAIN.TLD (des-cbc-md5)
In my case. my servers "real" name is hostname1 and i have an alias,
lets say mycrazyserver
/etc/hosts
127.0.0.1 localhost
192.168.0.1 hostname1.internal.domain.tld hostname1
mycrazyserver.internal.domain.tld
Host format:
IP REAL_HOSTNAME_FQDN ALIAS ALIAS
Note, adding mycrazyserver.internal.domain.tld should not be needed, because
that is resolved through dns.
ping mycrazyserver.internal.domain.tld will respond its reply with
hostname1.internal.domain.tld hostname1
If you add CIFS to you keytab you want to see :
3 cifs/hostname1.internal.domain.tld at REAL.DOMAIN.TLD
(aes128-cts-hmac-sha1-96)
3 cifs/hostname1.internal.domain.tld at REAL.DOMAIN.TLD
(aes256-cts-hmac-sha1-96)
3 cifs/hostname1.internal.domain.tld at REAL.DOMAIN.TLD (arcfour-hmac)
3 cifs/hostname1.internal.domain.tld at REAL.DOMAIN.TLD (des-cbc-crc)
3 cifs/hostname1.internal.domain.tld at REAL.DOMAIN.TLD (des-cbc-md5)
( + whats above )
Thats it..
So you output should look like this.

Luis, thank you very much, I followed the procedure step by step (which I had
already done) but unfortunately I always have the same error:

to temporary solve this problem I must extract the keytab of the oldsamba from
the domain controller and import with ktutil:

Hai,
I've re-read you thread, and there are a few things going-on..
I suggest you do the following..
Change these.
/etc/krb5.conf
[libdefaults]
default_realm = DOM.CORP
dns_lookup_kdc = true
dns_lookup_realm = false
forwardable = true
proxiable = true
kdc_timesync = 1
debug = false
/etc/samba/smb.conf
[Global]
workgroup = WG1
realm = DOM.CORP
# Netbios names in CAPS, see..
#
https://social.technet.microsoft.com/wiki/contents/articles/34981.active-directory-best-practices-for-internal-domain-and-network-names.aspx
#
https://support.microsoft.com/nl-nl/help/909264/naming-conventions-in-active-directory-for-computers-domains-sites-and
# Verify in DNS the following, A - PTR records for netbios name, setup
CNAME for all alias-names,
# point CNAME to the A record if which the PTR also exists..
netbios name = FS-A
netbios aliases = OLDSAMBA
security = ADS
#
kerberos method = secrets and keytab
dedicated keytab file = /etc/krb5.keytab
# renew the kerberos ticket
winbind refresh tickets = yes
ON THIS MEMBER... ( you dont run : samba-tool spn list ..... )
You run : net ads keytab
cp /etc/krb5.keytab{,.backup}
kinit Administrator
KRB5_KTNAME=FILE:/etc/krb5.keytab2 net ads keytab CREATE -P
Verify this keytab.
klist -ke /etc/krb5.keytab2
You want to see :
host/NETBIOSNAME at DOM.CORP ( x5 )
host/fqdn.hostname.dom.tld at DOM.CORP ( x5 )
NETBIOSNAME$@DOM.CORP ( x5 )
This you see these.. Then run this to add the cifs keytab.
KRB5_KTNAME=FILE:/etc/krb5.keytab2 net ads keytab ADD
cifs/fs-a.yourdns.domain.tld
KRB5_KTNAME=FILE:/etc/krb5.keytab2 net ads keytab ADD cifs/FS-A$
Verify the keytab file again.
klist -ke /etc/krb5.keytab2
If it all looks good.
Stop all samba service
rm /etc/krb5.keytab .. ( a backupfile is made if you followed above )
mv /etc/krb5.keytab2 /etc/krb5.keytab
That "should" do the trick..

Louis

[Samba] Failed to find cifs/fs-share@dom.corp (kvno 109) in keytab
Hai,
Nope.. To much again ;-)
This is one step to much:
step2:
# KRB5_KTNAME=FILE:/etc/krb5.keytab2 net ads keytab ADD cifs/oldsamba.dom.corp
at DOM.CORP
# KRB5_KTNAME=FILE:/etc/krb5.keytab2 net ads keytab ADD cifs/oldsamba at
DOM.CORP
# KRB5_KTNAME=FILE:/etc/krb5.keytab2 net ads keytab ADD cifs/oldsamba$@DOM.CORP
And why are you adding @REALM .. Do it exactly as shown below.
Because a CNAME resolves to the REAL hostname it's A record, then Kerberos
used the A of the real hostname and (might) verify the PTR also.
So again and exactly as show, because your "Default realm" is used
automaticly.
kinit Administrator
*(you see here: Password for Administrator at REALM: )
stop samba and related services.
rm /etc/krb5.keytab2
rm /etc/krb5.keytab
# i change the keytab to the needed name (/etc/krb5.keytab)
KRB5_KTNAME=FILE:/etc/krb5.keytab net ads keytab CREATE -P
net ads keytab create cifs/$(hostname -f)
Verify the output.
klist -ke /etc/krb5.keytab | sort
If you see the ALIAS hostname "oldsamba" again in the keytab file.
Then removed from smb.conf :
netbios aliases = OLDSAMBA
Verify the DNS and make sure your realhostname does have the A and PTR records
set.
And remove all A/PTR related records to OLDSAMBA.
Add the CNAME for OLDSAMBA and point to the realhostname.
Restart samba, repeat above.
Still failing..
Then get this script:
https://raw.githubusercontent.com/thctlo/samba4/master/samba-collect-debug-info.sh
Run it, anonymize it and post the output.
Greetz,
Louis

In my case. my servers "real" name is hostname1 and i have an alias,
lets say mycrazyserver
/etc/hosts
127.0.0.1 localhost
192.168.0.1 hostname1.internal.domain.tld hostname1
mycrazyserver.internal.domain.tld
Host format:
IP REAL_HOSTNAME_FQDN ALIAS ALIAS
Note, adding mycrazyserver.internal.domain.tld should not be needed, because
that is resolved through dns.
ping mycrazyserver.internal.domain.tld will respond its reply with
hostname1.internal.domain.tld hostname1
If you add CIFS to you keytab you want to see :
3 cifs/hostname1.internal.domain.tld at REAL.DOMAIN.TLD
(aes128-cts-hmac-sha1-96)
3 cifs/hostname1.internal.domain.tld at REAL.DOMAIN.TLD
(aes256-cts-hmac-sha1-96)
3 cifs/hostname1.internal.domain.tld at REAL.DOMAIN.TLD (arcfour-hmac)
3 cifs/hostname1.internal.domain.tld at REAL.DOMAIN.TLD (des-cbc-crc)
3 cifs/hostname1.internal.domain.tld at REAL.DOMAIN.TLD (des-cbc-md5)
( + whats above )
Thats it..
So you output should look like this.

to temporary solve this problem I must extract the keytab of the
oldsamba from the domain controller and import with ktutil:

Hai,
I've re-read you thread, and there are a few things
going-on..
I suggest you do the following..
Change these.
/etc/krb5.conf
[libdefaults]
default_realm = DOM.CORP
dns_lookup_kdc = true
dns_lookup_realm = false
forwardable = true
proxiable = true
kdc_timesync = 1
debug = false
/etc/samba/smb.conf
[Global]
workgroup = WG1
realm = DOM.CORP
# Netbios names in CAPS, see..
#
https://social.technet.microsoft.com/wiki/contents/articles/34981.active-directory-best-practices-for-internal-domain-and-network-names.aspx
#
https://support.microsoft.com/nl-nl/help/909264/naming-conventions-in-active-directory-for-computers-domains-sites-and
# Verify in DNS the following, A - PTR records for netbios
name, setup CNAME for all alias-names,
# point CNAME to the A record if which the PTR also
exists..
netbios name = FS-A
netbios aliases = OLDSAMBA
security = ADS
#
kerberos method = secrets and keytab
dedicated keytab file = /etc/krb5.keytab
# renew the kerberos ticket
winbind refresh tickets = yes
ON THIS MEMBER... ( you dont run : samba-tool spn list ..... )
You run : net ads keytab
cp /etc/krb5.keytab{,.backup}
kinit Administrator
KRB5_KTNAME=FILE:/etc/krb5.keytab2 net ads keytab CREATE -P
Verify this keytab.
klist -ke /etc/krb5.keytab2
You want to see :
host/NETBIOSNAME at DOM.CORP ( x5 )
host/fqdn.hostname.dom.tld at DOM.CORP ( x5 )
NETBIOSNAME$@DOM.CORP ( x5 )
This you see these.. Then run this to add the cifs keytab.
KRB5_KTNAME=FILE:/etc/krb5.keytab2 net ads keytab ADD
cifs/fs-a.yourdns.domain.tld
KRB5_KTNAME=FILE:/etc/krb5.keytab2 net ads keytab ADD
cifs/FS-A$
Verify the keytab file again.
klist -ke /etc/krb5.keytab2
If it all looks good.
Stop all samba service
rm /etc/krb5.keytab .. ( a backupfile is made if you followed
above )
mv /etc/krb5.keytab2 /etc/krb5.keytab
That "should" do the trick..

[Samba] Failed to find cifs/fs-share@dom.corp (kvno 109) in keytab
Ok, Your keytab looks ok now. oldsamba.dom.corp is an alias for fs-a.oldsamba.dom.corp. fs-a.dom.corp has address 10.0.0.2 i would have expected here. oldsamba.dom.corp is an alias for fs-a.dom.corp. fs-a.dom.corp has address 10.0.0.2 Or was that a typo? I assuming a typo.. About your setup from the script outpout. Change this one. /etc/hosts 10.0.0.2 fs-a.dom.corp fs-a oldsamba # Old/wrong 10.0.0.2 fs-a.dom.corp fs-a oldsamba.dom.corp oldsamba # new/correct Or 10.0.0.2 fs-a.dom.corp fs-a oldsamba.dom.corp # new/correct Here i personaly preffer : 10.0.0.2 fs-a.dom.corp fs-a And add the cname to the DNS. Why.. IP ALIAS1 ALIAS2.. Etc.. , but what i didnt tell before.. (sorry) ALIAS, if you use a "single lable" alias-name, as in, only the hostname-alias without the domain part. Then that hostname can/should only be use on the server, because, its missing the domain part. I do the same here, this is how i use it. ( from a 4.11.2 member to a .. yes 3.6.x server, i still have one running.. :-/ smbclient --option='client min protocol=NT1' //oldsamba/sharename -c 'ls' -k wont work here, dont ask why, that i dont know. To a 4.8+ member i use : smbclient //somealias/sharename -c 'ls' /etc/samba/smb.conf You can remove, these after testing, or set to no and use getent passwd/group username/groupname if you want to see the groups. winbind enum groups = yes winbind enum users = yes Why is this used : getwd cache = yes ? For my understanding, i think you can remove it, because this is should be handled differently in samba4. Your allowing : usershare allow guests = yes but you disable the share location : usershare path = or use it or disabled it, now its?? you tell me.. ;-) . but beside above points your setup looks pretty good. @Rowland, This might help you understanding my responce on this one.> You are creating a keytab, which may or may not be called /etc/krb5.keytab2^^^^^^^^ was only used to not accidently destroy his old keytab file. But since its replaced anyway now. Ps, keytab name is not significant. What is significantis, what is set for : default_keytab_name in krb5.conf Which ofcourse defaults to FILE:/etc/krb5.keytab> > Failed to find cifs/oldsamba at DOM.CORP(kvno 113) in keytab > > MEMORY:cifs_srv_keytab (arcfour-hmac-md5)] > > Then something reads the keytab in memory and cannot find the > required SPN, or to put it another way, whatever is trying to find the > SPN isn't reading the keytab you created above, it is reading the one in memory.Ok, this part above, yes, your right, its reading in memory, but to my believe, From: kerberos method = secrets and keytab, and as far i know "secrets" = MEMORY but ask youself, why is it using the "oldsamba" name if he is using oldsamba as aliasname. Thats the key here, so conclusion resolving problems/incorrectly setup. So there for im saying. ( typed this before i got the script output ). OLDSAMBA is still in /etc/hosts but before the newHostname Or it still has a dns A record. Or samba is also using the Netbios Alias names while creating keytab entries. ... And this, should in my opinion not happen, so lets wait what comes back. AND his keytab file is still incorrectly setup. And as i saw in the debug script output, i betting now on /etc/hosts that needs fixing. Resume.
