The Samba-Bugzilla – Bug 6255
cli_rpc_pipe_bind failed with error NT_STATUS_INVALID_PARAMETER
Last modified: 2009-09-09 08:16:25 UTC
I updated my samba PDC from 3.0.33 to 3.3.3 and now a lot of other tools fail.
A second server (still samba 3.0.33) on which winbind is running, not cannot connect anymore:
message on second server:

If it is a broken login the message should say this (but don't suppose that this is the reason) - I remember a quite similar problem with mod_smb_auth for apache when compiled with samba 3.0.0 - then there is no authentication possibl anymore against samba > 3.2
updating the second server to samba 3.3.3 solved the problem w/o rejoining the domain. - so it seems that there is something broken
Reproduced the spnego reply parse failure in 3-0-test winbindd while talking also to a 3.2.11 PDC.
Parts of the issues described here will be fixed with bug #6099.
Patches for bug #6099 will be included in 3.2.12 and 3.3.5.
Ok, that one is strange. Seems like winbind is not reseting the credential chain after having received NT_STATUS_INVALID_PARAMETER from the SamLogon call (due to broken credential chain).
Once I restart winbind, it usually works again.
Closing as fixed then.
