Update to latest AIX Toolbox Samba code (V4.16.5) breaks winbind

  • 1.  Update to latest AIX Toolbox Samba code (V4.16.5) breaks winbind

    Posted Wed November 09, 2022 11:35 AM
    On our test Samba server running AIX 7200-05-04-2220 code I upgraded the Samba code from V4.14.4 to the latest available (V4.16.5) but had to revert back because mapping network drives was no longer possible.  The Samba client log was posting errors such as:
     
    Auth: [SMB2,(NULL)] user [workgroup]\[smbadmin] at [Tue, 08 Nov 2022 15:47:21.964918 EST] with [NTLMv2] status [NT_STATUS_CONNECTION_DISCONNECTED] workstation [2UA6422BXX] remote
    host [ipv4:10.12.3.53:57617] mapped to [workgroup]\[smbadmin]. local host [ipv4:10.2.3.88:445]

    check_ntlm_password: Authentication for user [smbadmin] -> [smbadmin] FAILED with error NT_STATUS_CONNECTION_DISCONNECTED, authoritative=1

    On the AIX server the operating system error log filled with repetitive windbindd error messages:

    Running the "net ads testjoin" command results in:

    Reverting back to the previously installed Samba V4.14.4 code and all is well again, all such errors disappear...
     
    Is anyone successfully using the Samba V4.16.5 code?  Is there any known problems with it?  It is not working for me.

    Thank you --
