I added those lines (and changed the range to 10000-20000), and still
smbclient returns the same error.
"session setup failed: NT_STATUS_LOGON_FAILURE"
I also updated the krb5.conf file as I noticed some errors (Improper
format of Kerberos configuration file) in some of the logs. Those
errors are now gone, and the only idmap log file I see is
log.winbindd-idmap and it gives:
[EMAIL PROTECTED] etc]# more /var/log/samba/log.winbindd-idmap

And the second message (error) wasn't happening before. Am I missing a
module to provide the AD idmap backend? (although it looks like it is
trying to do it and failing)

Subject: Re: [Samba] Trouble authenticating to Samba shares with Win 2k3
ADS
Try using the following in your smb.conf
client signing = yes
client schannel = no
client use spnego = yes
client lanman auth = no
client NTLMv2 auth = yes
client plaintext auth = no
idmap domains = DOMAIN
idmap config DOMAIN:backend = ad
idmap config DOMAIN:default = yes
idmap config DOMAIN:schema_mode = rfc2307
idmap config DOMAIN:range = 1000 - 300000000
And for troubleshooting try taking a look at the
/var/log/samba/log.idmap* logs for UID/GID to SID mapping
Or you can use
%> wbinfo -i <USER>
%> wbinfo -n <USER>
%> wbinfo -s <USER>
Hope that helps some.

I may have a deficiency in understanding the procedure for ADS
authentication with samba, but most of the server setup works so far.
I
have bound a Red Hat Enterprise 5 server to our windows domain, it
shows
up in DNS and ADS, I can ping it, but I can't get samba shares to be
accessible to users, or even get the smbclient to return shares
properly.
wbinfo -g returns the domain groups properly
wbinfo -u return the domain users properly
[EMAIL PROTECTED] samba]# wbinfo -a 'DNAME\uname'%secret
plaintext password authentication succeeded
challenge/response password authentication succeeded
[EMAIL PROTECTED] samba]# wbinfo -K 'DNAME\uname'%secret
plaintext kerberos password authentication for [DNAME\uname%secret]
succeeded (requesting cctype: FILE)
credentials were put in: FILE:/tmp/krb5cc_0
[EMAIL PROTECTED] samba]# wbinfo -t
checking the trust secret via RPC calls succeeded
So that all works fine. smbclient chokes though:
[EMAIL PROTECTED] samba]# smbclient -L solar -U 'DNAME\uname'
Password:
session setup failed: NT_STATUS_LOGON_FAILURE
[EMAIL PROTECTED] samba]# smbclient -L solar -U uname
Password:
session setup failed: NT_STATUS_LOGON_FAILURE
or if I even use a samba user that I have setup with smbpasswd
[EMAIL PROTECTED] samba]# smbclient -L solar -U sambaname
Password:
session setup failed: NT_STATUS_LOGON_FAILURE
The only log file in /var/log/samba that shows any changes is log.nmbd
