Starting from possibly 3.0.7 Samba no longer resolves printer names successfully. 


Here's is the username map:

!smbop = christophk
zbenutzer = *

The smb.conf entry:

[hp43dpc]
        path = /tmp
        printable = Yes
        printer name = FWI-HP4300D
        cups options = "raw"

and the rpcclient output

rpcclient $> getprinter hp43dpc 2

... yes i know its for a different printer, but they are all configured the same
way and all dont work with >3.0.7


To me it seems that find_service called by set_printer_hnd_name doenst find a
share with the printername (due to the long printername) and then looks if the
servicename is a username and the share a homeshare. map_username called by
find_service changes the printername to a username, and then all subsequent
tries to map the long printer name to a share name in set_rpinter_hnd_name fail,
because the servicename was changed.
