[Samba] samba 3 member of win2003 domain + winbind can't see users

[Stuart Westbury]

Hi Samba gurus,

I have the following problem with a samba member server on a windows 2003
domain. I have managed to join the domain and my trust secret is good, but
I can't list users or groups using "wbinfo -u" or "wbinfo -g"

OS version 		Red Hat Enterprise Linux AS release 3 (Taroon)
Samba version		samba-3.0.9-1.3E.2
Kerb version		krb5-libs-1.2.7-38

This is the result from the join. It worked but produced this error :

net join ads -U admin
Password:

	[2005/03/18 3:41:00, 0] libads/kerberos.c:
ads_kinit_password(133) kerberos_kinit_password admin at AU.DOMAIN.INT
failed: ASN.1 encoding ended unexpectedly
	Joined domain AU

This is a similar error that I get when I use kinit :

kinit username at AU.DOMAIN.INT
Password for username at AU.DOMAIN.INT:
kinit(v5): ASN.1 encoding ended unexpectedly while getting initial
credentials

However, wbinfo -a username works fine (see below). Also, if I enter a
wrong password or username to kinit, it tells me the client does not
exist. Whats wrong with my kerberos?

The server now appears in the Active Directory, the trust secret is good,
and users can be authenticated  using "wbinfo -a", but when trying to list
users and groups, it hangs, and winbind must be restarted. I will show the
output of these commands here.

~> wbinfo -t
checking the trust secret via RPC calls succeeded

~> wbinfo -a domuser%PASSWD
plaintext password authentication succeeded
challenge/response password authentication succeeded

~> wbinfo -u (hangs for about 30 seconds)
Error looking up domain users

Winbind must then be restarted or "wbinfo -t" starts to fail with :

checking the trust secret via RPC calls failed
error code was  (0x0)
Could not check secret

I have also setup (in an attempt to solve this problem) a --set-auth-user.
I have tried both admin and non-admin accounts. When I do a tdbdump of the
secrets.tdb, I can see it in there and the details are correct, but I get
the same result. In the secrets.tdb, my domain is set to just AU, not,
AU.DOMAIN.INT. Is this correct? How do I even change it?

My config files are as follows :

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 = AU.DOMAIN.INT

[realms]
 au.domain.int = {
  kdc = dc001.AU.DOMAIN.INT:88
  kdc = dc002.AU.DOMAIN.INT:88
 }

[domain_realms]
.au.domain.int = AU.DOMAIN.INT
au.domain.int = AU.DOMAIN.INT

smb.conf

[global]

   workgroup = AU
   netbios name = aucbcosrv016
   realm = AU.DOMAIN.INT
   server string = Test Samba Server
   printcap name = /etc/printcap
   load printers = yes
   printing = lprng
   log file = /var/log/samba/%m.log
   max log size = 0
   security = ads
   winbind enum users = yes
   winbind gid = 10000-20000
   winbind enum groups = yes
   winbind uid = 10000-20000
   winbind cache time = 15
   winbind use default domain = yes
   name resolve order = hosts lmhosts wins bcast
   password server = aucbcosrv001 aucbcosrv002
   encrypt passwords = yes
   smb passwd file = /etc/samba/smbpasswd
   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
   dns proxy = no

<shares excluded>

nsswitch.conf

passwd:     files winbind
shadow:     files
group:      files winbind

Does this sound familiar to anyone? I've really hit a wall on this. Any
help would be greatly appreciated, and rewarded with lots of praise and
that warm fuzzy feeling :)

Thanks,
Stuart
