I try to use Win32API EnumPrinterDataEx to get registry key's values and data from Samba print server (of course I previously connect to the print queue and retrieve keys by EnumPrinterKey).
During the function execution (EnumPrinterDataEx) I collect ethereal trace to verify correct data is sent on wire and that Ethereal can correctly represent that info. Some of the keys parsed correctly by wireshark (DsSpooler for example) the others not (like PrinterDriverData). However any key value name and data fail to be correctly handled by EnumPrinterDataEx. The data received from print server is sequence of structures of type PRINTER_ENUM_VALUES. All the fields of the structure that aren't pointers are represented correctly, however pointers (that should contain actual memory address outside the structure and are set by adding offset value to the structure base address) contain only offset value w/o based struct memory address added to it, thus pointers indicate incorrect memory address. I tested same function execution when working with remote Windows print server and verified that pointers arithmetic is done. Here I brought the enumerated values buffer output for Samba and Windows print servers when EnumPrinterDataEx function is executed. Have anyone seen similar issue and can shed some light on this phenomena. Buffers base memory address for Windows case is 0x003a8390 and the offset for the ValueName is 60. Buffers base memory address for Samba case is 0x003a9d48 and the offset for the ValueName is 380. I use windows XP SP2 client. As one can easily see Samba buffer contains just offset value in hexadecimal presentation while windows buffer contains actual calculated memory reference inside the buffer space. Bolded are the values that ValueName pointer contains, first in the Samba call and second in the windows call.
