[Samba] debian unstable 3.0.4-3 panics

Mon May 24 00:50:11 GMT 2004

Hi All,

I had been doing some testing with the Debian 3.0.4-x versions of samba.
On two sepearte systems, running different configs, I've found that smbd
panics unless the [printers] section is removed from smb.conf.  Errors
generated as follows...

(System #1) Server role: ROLE_DOMAIN_MEMBER
Smb.conf...
[Global]
	 security = DOMAIN 
	 printcap name = cups
	 printing = cups

[printers]
       comment = All Printers
       path = /tmp
       printer admin = root, MYDOMAIN/lewis
       guest ok = Yes
       printable = Yes
       browseable = No

Smbd.log...
[2004/05/24 09:37:23, 0] smbd/server.c:main(757)
  smbd version 3.0.4-Debian started.

Looks like a bug to me...

	Anyone not got this issue with 3.0.4 sharing printers?
