guest access problem

Hello,
I'm having a problem with guest access. Either I'm misunderstanding how
the authentication process works, or this is a bug in Samba. I wonder if
somebody would be able to tell me which is the case.
The problem concerns guest access to a share. As I understand the
authentication process (as explained in the smb.conf man page), if a user
doesn't supply a correct password and a service is marked "guest ok", the
user should be granted access to the service as the guest user
I also understand that this should work regardless of whether or not
security = share, user, or server. However, in practice this does not seem
to be the case. In my experience, guest access is only properly granted in
when security = share. Here's an example that isolates the problem:
First, I use this minimal smb.conf file:
[global]
security = share
[tmp]
path = /tmp
guest ok = yes
read only = yes
smbclient allows me to connect to the share w/o a password:
(/usr/local/samba/lib)$ smbclient '\\FRODO\tmp' -N
Added interface ip=138.26.25.10 bcast=138.26.255.255 nmask=255.255.0.0
Server time is Sun Oct 19 23:41:33 1997
Timezone is UTC-5.0
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 1.9.17p2]
smb: \>
Next, I change security to user:
[global]
security = user
[tmp]
path = /tmp
guest ok = yes
read only = yes
This time smbclient asks me for a password. I enter a bad password, which
I think should have the effect of granting me guest access. It doesn't.
(/usr/local/samba/lib)$ smbclient '\\FRODO\tmp' -N
Added interface ip=138.26.25.10 bcast=138.26.255.255 nmask=255.255.0.0
Server time is Sun Oct 19 23:42:37 1997
Timezone is UTC-5.0
Password: <badpasswd>
Session setup failed for username=JDBLAIR myname=FRODO destname=FRODO
ERRSRV - ERRbadpw (Bad password - name/password pair in a Tree Connect or
Session Setup are invalid.)
You might find the -U, -W or -n options useful
Sometimes you have to use `-n USERNAME' (particularly with OS/2)
Some servers also insist on uppercase-only passwords
So... what am I missing? Have I misunderstood the authentication process?
thanks in advance for any help,
-john.
