pysmb copy file from Ubuntu to Windows network share folder

Question

From Ubuntu I am able to use pysmb to connect to a Windows network share and then list off all available shares and list all files and folders of the root of that share but nothing further down the tree. I need to access a folder 5 folder levels into the Shared path to copy a file to that location and cannot get past the root level of the file share.

I have tried to use forward slashes and backward slashes (single and double) between the paths and tried including and excluding the trailing slashes either way. I have tried only 1 level in and every one in between as well.

from smb.SMBConnection import SMBConnection

userid = 'myid'
password = 'mypassword'
client = 'clientMachine'
remote = 'remoteMachine'
server_ip = '5.5.5.5'

conn = SMBConnection(userid, password, client, remote, domain='MYDOM',use_ntlmv2 = True)
assert conn.connect(server_ip, 139)
sharelist = conn.listShares()
for s in sharelist:
    print(s.name)
filelist = conn.listPath('Shared','/')
for f in filelist:
    print(f.filename)

conn.close()

If I include any other path in the listPath call other than '/' I get the path is not found even though the paths I am trying are listed in the print statement:

Traceback (most recent call last):
  File "testsmb.py", line 14, in <module>
    filelist = conn.listPath('Shared', '/Corp/')

    raise failure
smb.smb_structs.OperationFailure: Failed to list Corp on Shared: Unable to open directory

I need to get into a share that is nested here:

//remotemachine/Shared/Corp/Futher/Futher with Space/Yet another Space/Test

I can see all the shares, I can even see the files and folders in each shares root level but no further in. I have permissions in all levels, what am I missing?
