Samba 3.0.21b The Samba docs indicate [0] we should be running changetrustpw [1] at some point (cron.daily) to update a machines trust account. However, I've seen multiple instances with 2 seperate AD environments where this breaks our ability to enumerate/authenticate with the domain. In both instances, we see something similar to the following in the winbind log...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hey, I'm running a Samba4 DC domain and I'd like to change the machine trust password of the current DC. This doesn't seem possible using net ads changetrustpw or net rpc changetrustpw on the DC itself, and I can't seem to find any command in samba-tool to achieve this. Is there any way to change the trust password of the DC? - -- Heiko Wundram. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJV1NwLAAoJEJ/eyTFUqXhdCRoP/iR0FWGjx5//u/g...

There is "net changetrustpw" to do this. When you domain-join the machine the machine password is managed by winbind, so you don't need to this. When you do not join the machine, there is no reason to have a machine account. If you just have a service that does LDAP-queries, I would create an ordinary user-acco...

...h incident, samba authorizes itself correctly on any other single PDC. It looks like if password for computer's account have been changed, and current PDC (wros001a) had not been notified about this fact yet. But is this possible? I've been fiddling around this way: issue 'net rpc changetrustpw' and then look at samba's log (after setting debug level high enough) -> after such move samba is authorizing users at the same PDC that was used to change the password. How often does smbd try password change? Maybe I should put 'net rpc changetrustpw' in my crontab, at s...

...seconds which is exactly 7 days. I'm not sure about disabling password change setting a 0 value to the machine password timeout parameters because it's a security feature and because it just worked before. Maybe I can try to force the password setting debug level to 10 using 'net ads changetrustpw' and see if I can reproduce the issue (users may be angry with another outage ...) Any help appreciated Thank you Alban

about 3 weeks ago there was a power outage where our main file server was not connected to any dc for some time. (don't know if that's related) since then winbind will randomly not resolve rfc_2307 users or groups whenever it feels like it. have tried shutting down nmbd,smbd.winbind and running net cache flush (and starting them up again)have tried turning off winbind group and user

I need to access the LDAP AD server from a debian box, but i don't need shares nor winbind. For a sake of simplicity i'm thinking to use machine account (-P). I can join the box, but if i keep winbind and nmbd/smbd off, how can i renew machine account? Thanks. -- M.C.S.E: Minesweeper Consultant & Solitaire Expert

.... We decided it would be easier to let samba handle the joining and managing of the krb5.keytab file as it did it more "properly" anyway. Now we can't seem to get ssh authentication working again. kinit username works as does kpasswd. We can run net ads keytab commands and net ads changetrustpw fine, but when we try to do what worked before, ssh username@localhost we now get the error "Key table entry not found". We have spent considerable time messing with the local hostname changing it from FQDN to short and whatnot, but to no avail. They keytab also appears to have entrie...
