Hi.

In

file
smbd/service.c

function
static connection_struct *make_connection_snum(int snum, user_struct *vuser,
					       DATA_BLOB password, 
					       const char *pdev,
					       NTSTATUS *pstatus)

section
	/* win2000 does not check the permissions on the directory
	   during the tree connect, instead relying on permission
	   check during individual operations. To match this behaviour
	   I have disabled this chdir check (tridge) */
	/* the alternative is just to check the directory exists */
	if ((ret = SMB_VFS_STAT(conn, conn->connectpath, &st)) != 0 ||
	    !S_ISDIR(st.st_mode)) {
		if (ret == 0 && !S_ISDIR(st.st_mode)) {
			DEBUG(0,("'%s' is not a directory, when connecting to "
				 "[%s]\n", conn->connectpath,
				 lp_servicename(snum)));
		} else {
			DEBUG(0,("'%s' does not exist or permission denied "
				 "when connecting to [%s] Error was %s\n",
				 conn->connectpath, lp_servicename(snum),
				 strerror(errno) ));
		}
		*pstatus = NT_STATUS_BAD_NETWORK_NAME;
		goto err_root_exit;
	}

	string_set(&conn->origpath,conn->connectpath);


- the SMB_VFS_STAT(...) not work with the link to directory, 
- the NT_STATUS_BAD_NETWORK_NAME error is one obscure error message, is more good NT_STATUS_OBJECT_PATH_NOT_FOUND, NO_SUCH_FILE, or other?


Example of the problem with share link to directory (with bad account access):
exnet= host with smbd
audio= share directory 'audio' with user access
gdbdesktop= share link to directory 'Desktop -> Scrivania' with user access


Ok with a share directory:
smbclient //exnet/audio
Enter gdb's password:
Anonymous login successful
Domain=[GDB.IT] OS=[Unix] Server=[Samba 3.3.7]
tree connect failed: NT_STATUS_ACCESS_DENIED

Ko with share link to directory
smbclient //exnet/gdbdesktop
Enter gdb's password:
Anonymous login successful
Domain=[GDB.IT] OS=[Unix] Server=[Samba 3.3.7]
tree connect failed: NT_STATUS_BAD_NETWORK_NAME 

(>>>>>> the right error is NT_STATUS_ACCESS_DENIED <<<<<)

(and after, for example, the kde smb browsing program not ask to the user the account data, and this cause the fail of the share browse)



And as final info, the share //exnet/gdbdesktop work fine with good account access:
smbclient //exnet/gdbdesktop
Enter gdb's password:
Domain=[EXNET] OS=[Unix] Server=[Samba 3.3.7]
smb: \> ls
