I've posted about this problem several times but so far nothing has worked.
Whenever I restart my samba servers the member server refuses to
authenticate users. Sometimes is will only authenticate some users on
some shares. Usually by fiddling with it I can eventually get it to
work but I can't identify the solution so I can replicate it. Once it
finally starts to work it works fine until the next restart.
"fiddling with it" means that I run a bunch of commands to try to
identify the problem and restarting the processes on the two servers. It
eventually starts working. I haven't been able identify which command
actually causes the system to start working. It doesn't appear to be the
same one every time. For example sometimes "net rpc join" seems to work,
but not this time.
Users on the XP machines can browse the network and see the Domain, both
servers and all of the shares on either server. They can access shares
on the PDC with no problem. When they attempt to access the shares on
the Member Server sometimes they get a user/password window and no
combination of user and password is accepted.
I'm completely stumped, which isn't hard. This is driving me nuts.
Among other commands I have run;
wbinfo -u and -g get what I expect, alist of users and groups
net status shares returns a list of shares
net status sessions return a list of sessions
getent passwd lists the domain users
getent group lists the groups including the domain groups
netlookup dc returns the correct ip address
netlookup master returns the correct ip address

If any other information would help let me know.
Here is my configuration.
Ubuntu 8.04 LTS AMD 64
Samba Version 3.0.28a
I have an NT style domain with XP pro desktops.
1 -PDC
1- Member Server
No AD No LDAP
On the PDC smbd and nmbd are unning
On the Member Server smbd nmbd and winbind are running.
Here is part of nsswitch.con;
passwd: compat winbind
group: compat winbind
shadow: compat winbind
Here is the Globals Section of the PDC
[global]
workgroup = ATLANTA
server string = %h mail passwd server (Samba, Ubuntu)
passdb backend = tdbsam
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\sUNIX\spassword:* %n\n
*Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully* .
syslog = 0

hostname lookups = Yes
logon path = \\THELMA\%U\.profiles

Here is the Globals for the Member Server

Here are two shares one worked and one didn't last time.

[Office]

This time neither work but this one does.
