Join Linux to Windows 2003 Active Directory Problem

**wearetherock** · 05-07-2008

I have to join fedora 6 to windows 2003 active directory, I followed this tutorial "http://www.planetmy.com/blog/how-to-join-fedora-core-6-samba-server-to-windows-2003-active-directory/"

Environment
windows 2003 sp 2, ip 10.80.27.122
fedora 6, ip 10.80.27.121, samba.i386 3.0.24-11.fc6

There are some problem that i can't solve, this is error message

Code:

[root@hotspot ~]# net join -U Administrator

Anyone can help me, thanks

after I got my kerberos smb login working on linux, I found this software Likewise – Making Linux and Windows work well together

I spent some good time automating my approach and then found that, already automated. look at that and if you would still rather do it manually let me know and I will compare notes and see if I can find the problem

**wearetherock** · 05-08-2008

Yes i really want to config manually, anyone known the message "failed to get schannel session key from server " how to fix it?

**matonb** · 05-13-2008

I really struggled to get an old RHEL2.1 (which should be fairly similar to RH6) server to connect to an AD but did eventually get it to work:

The Linux Servers hostname must be added to the Windows Active Domain Controller before it can join the domain.

The host option pre-win2K needs to be selected when you create the host entry.

Then on the Linux server as root enter the following command:

Code:

#smbpasswd -j <Domain Name> -r <PDC / ADS>

Example:

Code:

#smbpasswd -j WORKGROUP -r myDomainController

Note: No Windows Admin Account information is needed.

**wearetherock** · 05-14-2008

Above Commands

Code:

[root@hotspot samba]# smbpasswd -j TEST -r winac.test.sci.ubu.ac.th
See 'net join' for this functionality

Code:

[root@hotspot samba]# net ads join -U Administrator
Administrator's password: 
Using short domain name -- TEST
[2008/05/14 10:42:20, 0] utils/net_rpc_join.c:net_rpc_join_ok(70)
  net_rpc_join_ok: failed to get schannel session key from server winac.test.sci.ubu.ac.th for domain TEST. Error was NT_STATUS_ACCESS_DENIED
Failed to verify membership in domain!

Another Command

Code:

[root@hotspot samba]# wbinfo -u
TEST.SCI.UBU.AC.TH\administrator
TEST.SCI.UBU.AC.TH\guest
TEST.SCI.UBU.AC.TH\iusr_winac
TEST.SCI.UBU.AC.TH\iwam_winac
TEST.SCI.UBU.AC.TH\krbtgt
TEST.SCI.UBU.AC.TH\tonkhaw
TEST.SCI.UBU.AC.TH\wearetherock
TEST.SCI.UBU.AC.TH\x_kapong

Code:

[root@hotspot samba]# wbinfo -g
BUILTIN\administrators
BUILTIN\users
TEST.SCI.UBU.AC.TH\domain admins
TEST.SCI.UBU.AC.TH\domain users
TEST.SCI.UBU.AC.TH\domain guests

TEST.SCI.UBU.AC.TH\domain controllers
TEST.SCI.UBU.AC.TH\schema admins
TEST.SCI.UBU.AC.TH\enterprise admins
TEST.SCI.UBU.AC.TH\group policy creator owners
TEST.SCI.UBU.AC.TH\dnsupdateproxy

Seem i can list group/username on active directory server, but i can't authenticate a user via Kerberos.

Code:

I can't login using account on active directory server, see nsswitch.conf

Code:

[root@hotspot ~]# cat /etc/nsswitch.conf
#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Legal entries are:
#
#       nisplus or nis+         Use NIS+ (NIS version 3)
#       nis or yp               Use NIS (NIS version 2), also called YP
#       dns                     Use DNS (Domain Name Service)
#       files                   Use the local files
#       db                      Use the local database (.db) files
#       compat                  Use NIS on compat mode
#       hesiod                  Use Hesiod for user lookups
#       [NOTFOUND=return]       Stop searching if not found so far
#

# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd:    db files nisplus nis
#shadow:    db files nisplus nis
#group:     db files nisplus nis

#beer not comment
passwd:     winbind files
shadow:     winbind files
group:      winbind files

#passwd:     compat  winbind
#shadow:     conpat  winbind
#group:      compat  winbind


#hosts:     db files nisplus nis dns
hosts:      files dns

# Example - obey only what nisplus tells us...
#services:   nisplus [NOTFOUND=return] files
#networks:   nisplus [NOTFOUND=return] files
#protocols:  nisplus [NOTFOUND=return] files
#rpc:        nisplus [NOTFOUND=return] files
#ethers:     nisplus [NOTFOUND=return] files
#netmasks:   nisplus [NOTFOUND=return] files     

bootparams: nisplus [NOTFOUND=return] files

ethers:     files
netmasks:   files
networks:   files
protocols:  files winbind
rpc:        files
services:   files winbind

netgroup:   files winbind

publickey:  nisplus

Oops my bad, I thought you were using RH6 (which was around before Fedora came into existence) Which is why I suggested using the smbpasswd command.

Not very familiar kerberos so can't help you there I'm afraid. Good luck with fixing the problem, post your solution when you find one!

lets prove that. try this

Code:

klist

to see if you even have a ticket cached

Code:

kinit administrator_username

to get a kerb ticket

then run

Code:

klist

again and report back your results.

Thank you everybody, I have installed Ubuntu and followed this
https://help.ubuntu.com/community/Ac...ryWinbindHowto

Haven't any problem on Ubuntu all step is pass , except this command it still error

Code:

[root@hotspot raddb]# net join -U Administrator
Administrator's password: 
Using short domain name -- TEST
[2008/05/15 16:16:49, 0] utils/net_rpc_join.c:net_rpc_join_ok(70)
  net_rpc_join_ok: failed to get schannel session key from server winac.test.sci.ubu.ac.th for domain TEST. Error was NT_STATUS_ACCESS_DENIED
Failed to verify membership in domain!
ADS join did not work, falling back to RPC...
Unable to find a suitable server
Unable to find a suitable server
[root@hotspot raddb]#

But i don't care, becase on domain controller(Windows 2003) this machine has added into specific domain.
I can authenticate users via Kerberos then I use this same solution on fedora , It's also success

@jledhead , prove kerberos

Code:

[root@hotspot raddb]# klist 
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: administrator@TEST.SCI.UBU.AC.TH

Valid starting     Expires            Service principal
05/15/08 13:36:32  05/15/08 20:16:32  krbtgt/TEST.SCI.UBU.AC.TH@TEST.SCI.UBU.AC.TH
05/15/08 13:37:10  05/15/08 20:16:32  winac$@TEST.SCI.UBU.AC.TH
Kerberos 4 ticket cache: /tmp/tkt0
klist: You have no tickets cached

Code:

[root@hotspot raddb]# kinit administrator
Password for administrator@TEST.SCI.UBU.AC.TH:

Code:

[root@hotspot raddb]# klist 
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: administrator@TEST.SCI.UBU.AC.TH

Valid starting     Expires            Service principal
05/15/08 15:47:59  05/15/08 22:27:59  krbtgt/TEST.SCI.UBU.AC.TH@TEST.SCI.UBU.AC.TH
Kerberos 4 ticket cache: /tmp/tkt0
klist: You have no tickets cached
[root@hotspot raddb]#

Sory, I'm not a native english speaker.
I really thanks jledhead and matonb very much that attemp to help me. thanks
