Out of my league, but an online search suggest the error is due to KDC failing to generate a renewable ticket-granting ticket and one of the solutions consists in increasing the max_renewable_life.
You might try to analyze kinit/klist or the verbose output of the command called by the hourly cronjob (which is trying to refresh TGT for any service with KrbStatus prop set to “enabled”):
Thanks, I have completely doubled the values in krb5.conf.
Let’s see if it helps.
Everything works, but the error emails are annoying.
Since nothing was changed, did a Microsoft patch on the domain controllers cause this?
I have a Nethserver v7.9 and v6.10.
The v6.10 is the mail server.
When I have the time, I will redo this one and install a new one. An upgrade is probably not possible or not recommended, right?
I have now set the verbose switch.
Then at least the reports will be gone.
/ usr / libexec / nethserver / smbads -v tgt
I think I’d rather not do an in-place upgrade.
Thanks to virtualization, everything is so easy.
I’ll just set up a new Nethserver 7.9 and transfer all settings cleanly.
I think then I’ll have a lean and pure system afterwards. And then I can switch over when everything is finished and tested.
Let’s see.
