Only thing i can think of now is enable higher log levels in the problem member server so we can have a better look in to the problem. im out of options, you config looks good, and dont think its the vlanning. Add in smb.conf something like : log level = 3 passdb:5 auth:10 winbind:10 and wait again untill the problem exists. You may need to increase the max log size. Rowland, you any suggestions?

Change : kerberos method = secrets and keytab to kerberos method = secrets and wait again. I'll explain by giving this link. http://changelogs.ubuntu.com/changelogs/pool/main/s/samba/samba_4.3.6+dfsg-1ubuntu1/changelog Look at the last line bugfix in this change log of 4.3.6. Im testing here also, because this looks like its also involves the kerberos changes, now, i forgot what you was running, but this is an easy test. Is ntp installed on this machine, if not, install it and point it to the DC. Just to be sure. On the DC's, make sure your DC dont use any pool ntp servers. Point it to a stable ntp. ( preffered in germany, like, ntps1-0.eecsit.tu-berlin.de (130.149.17.21) ) Greetz, Louis -----Oorspronkelijk bericht----- Van: samba [mailto:samba-bounces at lists.samba.org] Namens Oliver Werner Verzonden: dinsdag 15 maart 2016 10:43 Aan: Rowland penny CC: samba at lists.samba.org Onderwerp: Re: [Samba] Problem with Winbind and Windows Clients Hi, So now i have same Problem with Logins.
