Hello all,

I'm configuring a samba printer in cups:

<Printer CM4540_Safecom>
AuthInfoRequired username,password
Info HP Color LaserJet CM4540 MFP
MakeModel HP Color LaserJet CM4540 MFP Postscript (recommended)
DeviceURI smb://URL
State Idle
StateTime 1379494304
Type 8425692
Filter application/vnd.cups-raw 0 -
Filter application/vnd.cups-command 0 commandtops
Filter application/vnd.cups-postscript 0 -
Accepting Yes
Shared No
JobSheets none none
QuotaPeriod 0
PageLimit 0
KLimit 0
OpPolicy default
ErrorPolicy stop-printer
</Printer>

and its ppd file is located at :

# ls /etc/cups/ppd/
CM4540_Safecom.ppd
	
In theory, every time I try to print I should see a dialog box asking
for user/passwd (it works in other distros like fedora), but it never
happens in SL 6.3 and then jobs are held with the error:

"Session setup failed: NT_STATUS_UNSUCCESSFUL"

Am I missing some configuration/package for this kind of configuration?

# rpm -qa|egrep '^cups|^samba'|sort
cups-1.4.2-50.el6_4.4.x86_64
cups-libs-1.4.2-50.el6_4.4.i686
