Hai Rowland,
yeah.. i know.
The DC's are using sernet-samba and the links arent there because i dont use it. ;-)
Thats the same with the "Proper sysvol replication solution..." threat..
Yes i have mixed XIDs on my DC's, but i have all correct UIDs on my sysvol.
and yes, samba-tool ntacl sysvolcheck gives. .
ERROR(<class 'samba.provision.ProvisioningError'>): uncaught exception etc...
but i dont mind. all my shares on the DC (sysvol and netlogon) ( used from within windows ) work 100% ok.
GPO is processed without errors so i dont care. i just dont run samba-tool ntacl sysvolcheck :-)
my logs on my DC are all (whole my debian server logs ) error free.
and i rechecked my windows logs after a login, after is saw the threat about it to be really long..
but same there 100% error free..
But thanks for the notice!
and for Ryan.
The debian Samba (backports 4.1.11 ) paths
Paths:
SBINDIR: /usr/sbin
BINDIR: /usr/bin
CONFIGFILE: /etc/samba/smb.conf
LOGFILEBASE: /var/log/samba
LMHOSTSFILE: /etc/samba/lmhosts
LIBDIR: /usr/lib/x86_64-linux-gnu
MODULESDIR: /usr/lib/x86_64-linux-gnu/samba
SHLIBEXT: so
LOCKDIR: /var/run/samba
STATEDIR: /var/lib/samba
CACHEDIR: /var/cache/samba
PIDDIR: /var/run/samba
SMB_PASSWD_FILE: /etc/samba/smbpasswd
PRIVATE_DIR: /var/lib/samba/private
just compare them with you local installed then stop samba, install backports samba, stop samba ( the backports version) copy the old files the above locations and start samba.
Greetz,
Louis
