[SOLVED]can't connect to SMB shares from Windows7 since migrating to OMV4

  • Hi everybody,
    I read a lot on the forum but I can't find any solution as I suppose there is not so much people still using Windows 7.
    I was using SMB shares on OMV3 and everything was fine.
    Since I migrate to omv4, I can't acces from my windows 7 station. Acces is OK with the same accounts on MacOs stations and Linux stations.
    looking at logs there's only one line repeating over and over :
    create_canon_ace_lists: unable to map SID S-1-5-80-2375682873-768044350-3534595160-1005545032-2873800392 to uid or gid.


    I can't understand what is going wrong....

  • If that can help, here is the smb part of /etc/openmediavault/config.xml :


    And my smb.conf file :

  • Hi everybody,
    I finally target what's wrong and it has nothing to do with the migration.
    In my Windows 7 I had to go to the security policy settings (secpol.msc) then go to Local Policies > Security Options > Network Security: LAN Manager authentication level



    and I had to change it from "Send LM and NTML replies" to "Send NTLMv2 response only" or "Send LM & NTLM - use NTLMv2 session security if negotiated"


    I don't really know why it was working before.... but it's working now.


    Hope this can help somebody.


    Bye
