 |
|
I have a problem connecting to a DFS share using `smbclient`. It does work using `mount -t cifs`.
Namely, when I do
| Code: | | sudo mount -t cifs //<dfs-url>/<service> ~/mountpoint/ -o username=<username> |
things work perfectly. However, doing
| Code: | smbclient //<dfs-url>/<service> -U <username> -W <workgroup>
Enter <username>'s password:
Domain=[<domain>] OS=[Windows Server 2012 R2 Datacenter 9600] Server=[Windows Server 2012 R2 Datacenter 6.3]
tree connect failed: NT_STATUS_BAD_NETWORK_NAME |
I would expect that if I can connect using a cifs mount, I should be able to connect using smbclient.
Am I doing something wrong with the smbclient invokation?
Has anbody managed to connect to a DFS share using smbclient? |

Couple of questions:
1) Is this Samba4? If so, which version? They have a couple on the go.
2) Wasn't the smbclient Samba3 based? It may use the old codebase for it's functions even in the Samba4 ebuild.
I seem to recall having to disable DFS to make my GPOs work, FWIW. There may yet be some missing functionality. |

1) 4.2.14 (testing, because stable 4.2.11 does not contain some fixes I need)
2) Perhaps, but on the net, there is plenty of mention smbclient being able to connect to DFS shares; it's usually cifs-mounting that people encounter issues with. |

| Does the smb client support the same security protocols ? |

I don't know, but seriously doubt that that is the problem, given the error message. |

You'd be surprised. Kerberos resolves separately in its own way (realm-based) from the transport. If auth fails, it could show as a connect fail that presents that way. (https://msdn.microsoft.com/en-us/library/cc246774.aspx)
Are you able to get a Wireshark trace to compare with the successful connection? That would clearly show how far it gets before failure. |
