[Bug 479955] Re: [SRU] winbind authentication fails after karmic upgrade

[Konna77]

** Description changed:

  Binary package hint: samba
  
  One of our users upgraded their Ubuntu workstation to 9.10 and they can
  no longer authenticate via pam_winbind with the domain controller (Samba
  3.3.7).
  
  # apt-cache policy winbind
  winbind:
-   Installed: 2:3.4.0-3ubuntu5
-   Candidate: 2:3.4.0-3ubuntu5
-   Version table:
-  *** 2:3.4.0-3ubuntu5 0
-         500 http://gb.archive.ubuntu.com karmic/main Packages
-         100 /var/lib/dpkg/status
+   Installed: 2:3.4.0-3ubuntu5
+   Candidate: 2:3.4.0-3ubuntu5
+   Version table:
+  *** 2:3.4.0-3ubuntu5 0
+         500 http://gb.archive.ubuntu.com karmic/main Packages
+         100 /var/lib/dpkg/status
  
  After the upgrade, the following messages appear in the winbind log
  every five minutes:
  
  [2009/11/10 11:45:01,  0] libsmb/ntlmssp_sign.c:208(ntlmssp_check_packet)
-   NTLMSSP NTLM2 packet check failed due to invalid signature!
+   NTLMSSP NTLM2 packet check failed due to invalid signature!
  [2009/11/10 11:45:01,  0] rpc_client/cli_pipe.c:620(cli_pipe_verify_ntlmssp)
-   cli_pipe_verify_ntlmssp: failed to unseal packet from host SKIPPY. Error was NT_STATUS_ACCESS_DENIED.
+   cli_pipe_verify_ntlmssp: failed to unseal packet from host SKIPPY. Error was NT_STATUS_ACCESS_DENIED.
  
  Attempting to authenticate results in the following:
  
  # wbinfo -a chrisa
  Enter chrisa's password:
  plaintext password authentication failed
  Could not authenticate user chrisa with plaintext password
  Enter chrisa's password:
  challenge/response password authentication failed
  error code was NT code 0x1c010002 (0x1c010002)
  error messsage was: NT code 0x1c010002
  Could not authenticate user chrisa with challenge/response
  
  And this message appears in the winbind log:
  
  [2009/11/10 11:44:58,  1] rpc_client/cli_pipe.c:948(cli_pipe_validate_current_pdu)
-   cli_pipe_validate_current_pdu: RPC fault code DCERPC_FAULT_OP_RNG_ERROR received from host SKIPPY!
+   cli_pipe_validate_current_pdu: RPC fault code DCERPC_FAULT_OP_RNG_ERROR received from host SKIPPY!
  
  This appears to match the behaviour mentioned in the upstream bug #6646 which was fixed in Samba 3.4.1:
-   https://bugzilla.samba.org/show_bug.cgi?id=6646
+   https://bugzilla.samba.org/show_bug.cgi?id=6646
  
  Patch looks quite trivial.  Would it be possible to backport it?
  
  Thanks,
  Chris
