samba - Oct 1998 - Help URGENT : Password for IPC$ and public shares - more info

yesterday i saked for help because :
- I set a valid guest account (suid to it permit me to use printer)
- I defined a printer share publicly accessible
- my server is in secutity = user and I need to stay it like that

when trying to access to the server from an account not existing on the
Unix part, Samba asks for a password for IPC$

what is wrong in my configuration?


[global]
...
   printing = bsd
   printcap name = /etc/printcap.smb
   load printers = yes
   printer driver file=/home/samba/print/drivers/printers.def

   guest account = sambaguest
   log file = /var/log/samba-log.%m
   username map = /etc/smb.map

   security = user


[testprt]
   comment = Imprimante PENTAPRT test
   path = /var/spool/samba
   browseable = yes
   printable = yes
   public = yes
   writable = no
   print command = /home/samba/print/pentaprt.pl '%U' '%m'
'%s'
   printer driver=IBM 4029 LaserPrinter PS39
   printer driver location=\\%L\PRINTER$\ibm


pentaprt.pl is a script i did to print with accounting, front page
generation, .... and this script works fine


I try a level 3 debug and here is what i get when i try to connect :

error string = Connection refused


when adding a line to map michel to existing user in mapping file, all
works perfectly (i have to authentified myself as that user)...

following the logs, it appears that the server never tried to get on guest
account, trying three times the user but not the guest account....
