[Samba] NT_STATUS_LOGON_FAILURE error message

[Dathan Bennett]

Hello, all.  I'm running into an issue connecting from my PowerMac G4 
running Yellow Dog 4.0.1 to our server, which is a dual AMD running Fedora 
Core 2.  The server is running samba version 3.0.10-1.fc2, and the g4 is 
running samba version 3.0.10-1.ydl.1.

I can connect from the g4 anonymously to a share point on localhost:
smbclient //localhost/dathan

I can connect from the server to the same share point on the g4 anonymously:
smbclient //g4/dathan

I can connect from the server to itself (we have a number of different share 
points setup, and all of them work):
smbclient //localhost/raid -Udathan%password
Also, explicitly naming the server works, too:
smbclient //server/raid -Udathan%password

However, I cannot connect from the g4 to the server:
smbclient //server/raid -Udathan%password -d3
yields the following:
lp_load: refreshing parameters

I guess that, since server will connect to itself, but g4 won't connect to 
server, that it's some sort of incompatibility in their configurations, so 
here are the [global] sections from the two smb.conf's:
server:
[global]
workgroup = mygroup
server string = Samba Server
printcap name = etc/printcap
load printers = yes
log file = /var/log/samba/%m.log
max log size = 50
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
password server = None
dns proxy = no
idmap uid = 16777216-33554431
idmap gid = 16777216-33554431
template shell = /bin/false
guest ok = yes
username map = /etc/samba/smbusers
winbind user default domain = no

g4:
[global]
workgroup = MYGROUP
server string = Samba Server
printcap name = /etc/printcap
load printers = yes
cups options = raw
log file = /var/log/samba/%m.log
max log size = 50
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
name resolve order = host wins lmhosts bcast
dns proxy = no
idmap uid = 16777216-33554431
idmap gid = 16777216-33554431

winbind use default domain = no

I appreciate any help you can give.

Thanks,
Dathan
