Smb2Client ListShares and TreeConnect fail when using dll built with SMB311_CLIENT

[DevDevDeveolper]

Hi,

When I use 1.5.3.5 built by myself without extra constants or with SMB302_CLIENT, everything works fine.

Once I define both SMB302_CLIENT and SMB311_CLIENT, it fails regarding ListShares or TreeConnect for SMB servers, even if they are not requiring SMB 3.11. This happened on smbd 4.19.5 on Ubuntu 24.04 with min_protocol SMB3_00, SMB3_02, SMB3_11 and on a Windows 11 shared folder.

private string ipAddress = "192.xx.xx.xx";
private string username = "username";
private string password = "password";
...
SMB2Client smb2Client = new SMB2Client();
bool isConnected = smb2Client.Connect(IPAddress.Parse(ipAddress), SMBTransportType.DirectTCPTransport);

NTStatus ntStatus = smb2Client.Login(String.Empty, username, password);  

if(ntStatus == NTStatus.STATUS_SUCCESS) {            
            List<string> shares = smb2Client.ListShares(out ntStatus);
            ...
}

It does connect, it does login, but then for ListShares the ntStatus is STATUS_ACCESS_DENIED.

Knowing what share should have been reported, I tried TreeConnect, which gives the same status message of STATUS_ACCESS_DENIED.

ISMBFileStore fileStore = smb2Client.TreeConnect(shareName, out ntStatus);

When I replace the dlls built with SMB302_CLIENT and SMB311_CLIENT with the ones built only with SMB302_CLIENT, the same code works without issues.

Do you have any advice? Is something missing?

Thanks!

SMB 3.11 client support is experimental, but it should work.
I will try to find time to recreate this.
