[Samba] lib/util.c:smb_panic(1614)

[Matthew Davidson]

Hello All

I am setting up a new samba server. It is a stand alone server and just
needs a simple file share.

Some info first:
Harware:
HP ML 570

O/S:
Fedora Core 5 with all updates

uname -a = Linux "hostname removed" 2.6.18-1.2200.fc5smp #1 SMP Sat Oct
14 17:15:35 EDT 2006 i686 i686 i386 GNU/Linux

rpm -qa | grep samba
system-config-samba-1.2.34-1
samba-common-3.0.23c-1.fc5
samba-client-3.0.23c-1.fc5
samba-3.0.23c-1.fc5

I add a group

 groupadd mygroup

I add my users to linux:

 useradd -g mygroup -s /bin/false -d /dev/null user1

 smbpasswd -a user1

Standard config file with this added that works:
[myshare]
   comment = myshare
   path = /myshare
   valid users = user user1 user2
   public = no
   writable = yes
   printable = no
   create mask = 0765

testparm smb.conf gives no errors and i can connect to share

this does not work
[myshare]
   comment = myshare
   path = /myshare
   valid users = @mygroup
#   valid users = user user1 user2
   public = no
   writable = yes
   printable = no
   create mask = 0765

testparm smb.conf gives no errors, but when I try to connect I get the
error

\\nameofserver\myshare is not accessible You might not have permission
to use this network resource

The specified network name is no longer avaiable

The same exact setup works on another server, and I am not sure what I
have done.

Any Ideas?
