[jcifs] Re: ACLs - SmbException: Incorrect function

[Thomas Bley]

Hello,

I have the same problem. Here is what I found out so far:
When Windows explorer is the client, it starts the DCERPC with the 
command "Write AndX" (0x2f).
When JCIFS is the client, it starts DCERPC with "TransactNmPipe" (0x0026).
Windows servers and Samba understand the TransactNmPipe very well, but 
for some reason NetApp doesn't.
My tests were made with a NetApp FAS3050; OS-Version Ontap 7.1.1.

If the error is happening, jCIFS falls back to NetShareEnum methods 
which resolve share names, but without unicode characters and only up to 
12 characters in length.
Maybe it is an older method which requires some compatibility setting 
enabled in the NetApp machine (maybe sth. like enable WindowsNT 
compatibility, enable namedpipe rpcs, etc.). Do you have any idea or 
maybe you can even ask the NetApp support for this ?
(if required, I can provide some Ethereal traces)

bye
Thomas
