[Samba] Failed to find cifs/fs-share@dom.corp (kvno 109) in keytab

Hi, the problem seems to be related to this bug:

  https://bugzilla.samba.org/show_bug.cgi?id=6750

I try therefore to set

  machine password timeout = 0

[Samba] Failed to find cifs/fs-share@dom.corp (kvno 109) in keytab

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..

Greetz, 

Louis

[Samba] Failed to find cifs/fs-share@dom.corp (kvno 109) in keytab

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:

[2019/11/05 11:49:47.748159,  1]

please pay attention to (kvno 113) the problem is here and not the keytab
file.

to temporary solve this problem I must extract the keytab of the oldsamba

[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. 

       7 cifs/FS-A at DOM.CORP (aes128-cts-hmac-sha1-96)
       7 cifs/FS-A at DOM.CORP (aes256-cts-hmac-sha1-96)
       7 cifs/FS-A at DOM.CORP (arcfour-hmac)
       7 cifs/FS-A at DOM.CORP (des-cbc-crc)
       7 cifs/FS-A at DOM.CORP (des-cbc-md5)
       7 cifs/fs-a.dom.corp at DOM.CORP (aes128-cts-hmac-sha1-96)
       7 cifs/fs-a.dom.corp at DOM.CORP (aes256-cts-hmac-sha1-96)
       7 cifs/fs-a.dom.corp at DOM.CORP (arcfour-hmac)
       7 cifs/fs-a.dom.corp at DOM.CORP (des-cbc-crc)

keytab
	
	
	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:
	

	[2019/11/05 11:49:47.748159,  1]
../../source3/librpc/crypto/gse.c:660(gse_get_server_auth_token)
	
	  gss_accept_sec_context failed with [ Miscellaneous failure (see text): Failed
to find cifs/oldsamba at DOM.CORP(kvno 113) in keytab MEMORY:cifs_srv_keytab
(arcfour-hmac-md5)]
	

	please pay attention to (kvno 113) the problem is here and not the keytab file.
	

	klist -ke /etc/krb5.keyatb

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

	# ktutil
	ktutil:  rkt oldsamba.keytab
	ktutil:  l
	slot KVNO Principal

	   3  112           cifs/oldsamba at DOM.CORP 
	   4  113           cifs/oldsamba at DOM.CORP 
	   5  113           cifs/oldsamba at DOM.CORP 
	   6  113           cifs/oldsamba at DOM.CORP 
	

	please note the kvno column.

		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..
		
		
		
		Greetz,
