[CentOS] error when join my Centos machine to win2003 ADS server

Dear All,

I have succesfully managed to have my kerberos configured n working
without error when i say

kinit Administrator
and after entering password it works fine

my krb5.conf
--------------

[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log

[libdefaults]
 default_realm = BALADIA.LOCAL
 dns_lookup_kdc = false

 dns_lookup_realm = false
[realms]
BALADIA.LOCAL = {
   default_domain = baladia.local
  kdc = 172.16.2.227:88
  admin_server = 172.16.2.227:749
  kdc = KMUN
}

[domain_realm]
baladia.local = BALADIA.LOCAL

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

klist shows

icket cache: FILE:/tmp/krb5cc_0
Default principal: Administrator at BALADIA.LOCAL

Valid starting     Expires            Service principal
03/26/09 11:33:04  03/26/09 21:33:18  krbtgt/BALADIA.LOCAL at BALADIA.LOCAL
        renew until 03/27/09 11:33:04


Kerberos 4 ticket cache: /tmp/tkt0
klist: You have no tickets cached

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

now i configured /etc/samba/smb.conf but when i try to join the domain

 net ads join -U Administrator
Administrator's password:
[2009/03/26 21:58:05, 0] utils/net_ads.c:ads_startup_int(286)
  ads_connect: No logon servers
Failed to join domain: No logon servers

after googling and tryin various options in /etc/samba/smb.conf file here
is the latest smb.conf file
---------------------

[global]
#--authconfig--start-line--

# Generated by authconfig on 2009/03/26 12:50:28
# DO NOT EDIT THIS SECTION (delimited by --start-line--/--end-line--)
# Any modification may be deleted or altered by authconfig in future

   workgroup = BALADIA.LOCAL
;   password server = kmun.baladia.local
   password server = 172.16.2.227
   realm = KMUN.BALADIA.LOCAL
   security = ads
   idmap uid = 16777216-33554431
   idmap gid = 16777216-33554431
   winbind separator = +
   template shell = /bin/bash
   winbind use default domain = true
   winbind offline logon = false
   encrypt passwords = yes
  log level = 3
#--authconfig--end-line--
        encrypt passwords = yes
       dns proxy = no
       server string = Samba Server Version %v
       os level = 20
      client use spnego = no
        server signing = auto

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

where i could be goin wrong
i would be thankful and really apprecite your advice for any setting in my
smb.conf file

Is there anything else to check

when i run testparam it gives no errors

thnks and Regards

Fabian

Can you get to the ADS netlogon share?  It is //domainname/netlogon
which may be
//baladia.local/netlogon/    on your network.

//172.16.2.227/netlogon ?

Further, even connecting WinVista to a domain will sometimes require
raw editing of the hosts properties in LDAP.   SysInternal's
adexplorer.exe or jexplorer (don't use java 1.6) are good at this.
Specifically, you will want to make sure dnsHostName and
servicePrincipalName (SPN) are correct.  If not, these tools with the
domain admin privilege will let you edit these ldap entries directly.
Use a known good ADS connected node as an example.

There is a list of apps based on python-ldap at
http://python-ldap.sourceforge.net/apps.shtml
Some of those would provide adexplorer.exe type functionality, but i
haven't tried them for editing.  Hmmm, now i wonder if they work at
all with Samba b/c python hooks were removed in Samba 3.2.0 due to
lack of maintenance???

I would like a script that could be run on a Windows ADS server, a ADS
domain connected windows client, and linux.  The script would generate
and verify everything needed to successfully connect.  SASL required?
Unsecured or Secured auth?   kerberos and ldap identifiying info.
ldapenum.pl was an attempt at this.

You will want to read the announcement for Samba 3.2 which i am not
sure if 3.2 is in the CentOS release repo or not.  i ended up using
fc9/fc10 for ads joins.  EnterpriseSamba.com may still be your best
bet for CentOS.

1. It's usually better to set "password server" to "*".
2. Your realm is wrong; it should be just the domain, baladia.local.
3. Add "netbios name = [your server's hostname]"
4. Add "wins server = [your wins server(s)]"
5. "client use spnego" should likely be "yes"
6. Add "client ntlmv2 auth = yes".
7. Add "smb ports = 445"
8. Add "local master = no"
9. Add "domain master =no"
10. Add "preferred master = no"

I don't know if that's going to solve your problems.  "no logon
servers"
indicates either a deeper problem (e.g. network issue), or simply that
you've specified the wrong server to use for checking passwords against.

BTW, I still don't know why you have two "kdc" entries in your
krb5.conf
file. You only need one.

Regards,

Ranbir
