To see which DC is used by Windows client: open a MSDOS console, type "set", look for LOGONSERVER=\\<your_dc> <your_dc> is the DC used to connect on. If issue comes from one DC I would have on sysvol synchronisation between DC, ACL on all sysvol, DNS entries (but I don't think that's a DNS issue if you have only GPO issue). 2016-03-29 14:51 GMT+02:00 Sébastien Le Ray <sebastien-samba at orniz.org>:> Hi > > Same here, GPO work without UID/GID on machine account (since issue > "resolves" itself sometime) > > It really seems to depend on which DC is chosen at start. > > One of the affected machine just recovered without any change except a > reboot > > So I guess root issue is the kerberos one "max reference tickets exceeded" > but cannot see why it happens and on which DC > > I noticed this morning that sysvolcheck returns errors that won't be fixed > by sysvolreset (!), I manually fixed ntacl but this does not seem to have > fixed anything > > Regards > > > > > Le 29/03/2016 11:57, mathias dufresne a écrit : > >> I'm not an expert in idmap (at all in fact :p) but I thought idmap stuffs >> were here to replace RFC2307 UID/GID declared into AD/LDAP objects. >> In others words, if you configure correctly idmap into smb.conf I expect >> you don't need any more declaring UID/GID for machine accounts. >> >> Anyway here my machines get access to their GPO: I tested one computer's >> GPO this morning, the one giving the possibility to use userPrincipalName >> without @samba.domain.tld when logging into a computer.

About sysvolreset errors: send them to us. There is (at least) one error from sysvolcheck which is not too much important (if I have well understood it): ACL is set on FS to Local Admins when it should be Domain admins (or the contrary). That one should be a simple warning, or it is and it can be ignored (once more: according to my memory). 2016-03-29 15:14 GMT+02:00 mathias dufresne <infractory at gmail.com>:> To see which DC is used by Windows client: open a MSDOS console, type > "set", look for LOGONSERVER=\\<your_dc> > > <your_dc> is the DC used to connect on. > > If issue comes from one DC I would have on sysvol synchronisation between > DC, ACL on all sysvol, DNS entries (but I don't think that's a DNS issue if > you have only GPO issue). > > 2016-03-29 14:51 GMT+02:00 Sébastien Le Ray <sebastien-samba at orniz.org>: > >> Hi >> >> Same here, GPO work without UID/GID on machine account (since issue >> "resolves" itself sometime) >> >> It really seems to depend on which DC is chosen at start. >> >> One of the affected machine just recovered without any change except a >> reboot >> >> So I guess root issue is the kerberos one "max reference tickets >> exceeded" but cannot see why it happens and on which DC >> >> I noticed this morning that sysvolcheck returns errors that won't be >> fixed by sysvolreset (!), I manually fixed ntacl but this does not seem to >> have fixed anything >> >> Regards >> >> >> >> >> Le 29/03/2016 11:57, mathias dufresne a écrit : >> >>> I'm not an expert in idmap (at all in fact :p) but I thought idmap stuffs >>> were here to replace RFC2307 UID/GID declared into AD/LDAP objects. >>> In others words, if you configure correctly idmap into smb.conf I expect >>> you don't need any more declaring UID/GID for machine accounts. >>> >>> Anyway here my machines get access to their GPO: I tested one computer's >>> GPO this morning, the one giving the possibility to use userPrincipalName >>> without @samba.domain.tld when logging into a computer.

LOGONSERVER is the server used to authenticate currently logged in user, this does not mean that it is the one on which machine GPO was fetched (which seem to be round-robinized, but maybe not) Got no more sysvolcheck error, manually fixed those (what a pain) But still, events log show a warning about kerberos ticket from LsaSrv source and right after a permission denied on GPT.ini Regards Le 29/03/2016 15:16, mathias dufresne a écrit :> About sysvolreset errors: send them to us.
