Re: [Samba] Samba fileserver member corrupt smb.ldb after joining 4.8.4 Samba DC




Hi,

thanks for your suggestions. Do you think this is causes the stacktrace
above? . I just added "REALM" as a placeholder and it worked on a DC that
was provisioned using Samba 4.7.3 and upgraded afterwards to Samba 4.8.4
absolutely fine with this config and the command "samba-tool ntacl get
/srv/profiles" returns the correct ACLs of this directory.

When I interprete this correctly it seems that the Fileserver is unable to
find the DomainSID. Normally the command "ntacl get" should return the ACLs
and not that stacktrace, should'nt it :).

Thanks in advance!
