Samba win 98 authentication problem

[raja_s_patil]

Hi,

Kubuntu 8.04.1, samba 3.0.28a, Home network of 3 Pcs

Samba server is configured and from XP Pcs all shares are accessible.
But from win98SE pc i am getting authentication error the log says

[2009/03/01 17:47:16, 3] libsmb/ntlm_check.c:ntlm_password_check(455)
ntlm_password_check: LM password, NT MD4 password in LM field and LMv2 failed for user rsp

[2009/03/01 17:47:16, 2] auth/auth.c:check_ntlm_password(319)
check_ntlm_password: Authentication for user [RSP] -> [RSP] FAILED with error NT_STATUS_WRONG_PASSWORD

config file is

[global]
workgroup = RSP
server string = %h Samba server on Ubuntu
interfaces = vmnet1
map to guest = Bad User
# obey pam restrictions = Yes
# passdb backend = tdbsam
# pam password change = Yes
# passwd program = /usr/bin/passwd %u
# passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
# unix password sync = Yes
syslog = 0
log file = /var/log/samba/log.%m
max log size = 1000
acl compatibility = winnt
server signing = auto
preferred master = No
domain master = No
dns proxy = No
# ldap ssl = no
usershare allow guests = Yes
panic action = /usr/share/samba/panic-action %d
invalid users = root
admin users = root
create mask = 0777
directory mask = 0777
guest ok = Yes
config file = /etc/samba/smb.conf.%U

log level = 3
encrypt passwords = yes

lanman auth = yes
ntlm auth = Yes

client lanman auth = Yes
client ntlmv2 auth = Yes

client plaintext auth = No


Confirmed on 98 pc that plaintext password registry setting is disabled.

Thanks and best regards

raja, i have a few quick questions for you about your issue.

0. windows 98?
1. can you share from one of your xp machines to the 98 machine?
2. does it work if you disable athentication?

if i remember correctly you can't share from xp to 98 they have "issues"

and your machines have to be named correctly like no special chars, also in the same workgroup.(check m$ knowlage base for that one)

i suspect that your "samba" server is acting as if its xp and/or does not properly conform to the 98 naming convention (or perhaps ur usr/pass is your issue)

hope that helps
sith

Well,

I just found solution for the problem. The problem is
win 98 is using lanman rather than NTLMv2 as XP is using
and Samba is accepting lanman for authetication. So I searched
to initialize 98 with NTLMv2 authentication and I found the solution

1> In smb.conf add following lines in [Global] Section
ntlm auth = Yes
client ntlmv2 auth = Yes
2> Restart Samba

3> Download https://fp.arizona.edu/accounts/dsclient/98DSCLIENT.exe
4> Run it (but donot restart since we going restart soon even if u restart doesn't matter,
u loose few minutes that's all)
5> in 98 Create following key - KEY_LOCAL_MACHINE\System\CurrentControlSet\Control \Lsa
6> Add dword value in it "LMCompatibility"=dword:00000003
7> restart win98

Thats all u start accessing XP, Samba, win98 network seemlessly.
(just tested it in vmware with three VMs so no doubts of any kind)

I going to test it further rest of the day before taking it to production system.

Thanks and best regards
