[Samba] can't join W2003 domain with 3.0.0 (krb ticket is OK though)
Hi everyone,
I'm using the production release of 3.0.0 and can not join a W2003 domain:
[printsrv4] /spool/samba-3.0.0/bin $ ./net -d 10 ads join -Uhumpty_dumpty
[2003/10/29 15:35:39, 3] libads/sasl.c:ads_sasl_spnego_bind(191)
got principal=adc1$@WIN.DESY.DE
[2003/10/29 15:35:39, 1] libsmb/clikrb5.c:ads_krb5_mk_req(269)
krb5_cc_get_principal failed (No credentials cache found)
[2003/10/29 15:35:40, 10] libsmb/clikrb5.c:get_krb5_smb_session_key(385)
Got KRB5 session key of length 16

ads_connect: Strong authentication required
[2003/10/29 15:35:40, 2] utils/net.c:main(758)
return code = -1
The krb5 token looks OK:

See smb.conf Manpage about "client ntlmv2 auth" (and maybe also about "client schannel", "client signing", "client use spnego") Greetings Jochen> [2003/10/29 15:35:40, 2] utils/net.c:main(758) > return code = -1 > > The krb5 token looks OK: > > [printsrv4] /spool/samba-3.0.0/bin $ klist > Ticket cache: FILE:/tmp/krb5cc_0 > Default principal: humpty_dumpty@WIN.DESY.DE > > Valid starting Expires Service principal > 10/29/03 13:48:09 10/29/03 23:48:18 krbtgt/WIN.DESY.DE@WIN.DESY.DE > renew until 10/30/03 13:48:09 > > > Kerberos 4 ticket cache: /tmp/tkt0 > Principal: humpty_dumpty@DESY.DE > > Issued Expires Principal > 10/21/03 15:42:14 10/22/03 17:08:35 krbtgt.DESY.DE@DESY.DE > 10/21/03 15:42:14 10/22/03 17:08:35 afs@DESY.DE > 10/22/03 15:18:13 10/22/03 17:13:13 rcmd.host@DESY.DE-- -------------------------------------------------------------------- Jochen Schmidt jochen.schmidt@millenux.com Mi||enux GmbH mobile: +49.175.5752483 Lilienthalstra?e 2 phone: +49.711.88770.300 70825 Stuttgart-Korntal fax: +49.711.88770.349 -= linux without limits -=- http://linux.zSeries.org/ =- PGP Fingerprint: 6F9A 85CE 78EA 7EF1 B2BA 3559 8FA1 2B13 098D 20B5

Hi Jochen, on another security issue, how do your samba servers authenticate to your idmap ldap backend server? Do you have to allow anonymous write access? I certinly would feel this was poor if that's the case. And you have listed only one LDAP server as your backend, will this not cause a big problem if it falls over? Can you specify more than one LDAP backend server? thanks Andy Smith. -----Original Message----- From: samba-bounces+pubsyssamba=bbc.co.uk@lists.samba.org [mailto:samba-bounces+pubsyssamba=bbc.co.uk@lists.samba.org]On Behalf Of Jochen Schmidt Posted At: 31 October 2003 11:59 Posted To: Samba Conversation: [Samba] can't join W2003 domain with 3.0.0 (krb ticket is OK though) Subject: Re: [Samba] can't join W2003 domain with 3.0.0 (krb ticket is OK though) Hi Christoph On 31 Oct 2003, Andrew Bartlett wrote:> On Fri, 2003-10-31 at 21:41, christoph.beyer@desy.de wrote: > > Hi Jochen et al, > > > > that worked fine, though if I get it right everyone can now read the > > active directory structure (?) > > No, you still need to authenticate, but nothing stops an attacker from > 'stealing' the TCP/IP connection, if they control the network.If you want see what *everybody* can see try an "ldapsearch -x -b "dc=MYDOMAIN,dc=DE" -h adscontroller -p 389" on a UNIX-Box.> > Connecting to the samba machine results still in errors, but that may be > > something stupid on my behalf too... > > > > thanks for helping > > ~christoph > > > > > > connect_to_domain_password_server: unable to setup the NETLOGON > > credentials to machine ADC1.

The Winbind-Stuff comes from an other LDAP-Server and has no relation to the ADS-LDAP. If you don't use winbind you won't need the winbind section. You should first do the "kinit Administrator@REALM" and then a "net ads join".
