Ok, so to summarize: - sssd is providing user and groups from AD (via /etc/nsswitch.conf) - realmd was used to join the machine to AD for the above - local user authentication is done via pam_sss and using kerberos. Shell users get a ticket upon login - samba is not using winbind
I have a feeling samba is missing it's account with the AD server. I don't know if the sssd join works for samba's "security = ADS", I have never tested that. I always used net ads join. Is this how you configured the non-18.04 samba member servers? With just sssd, no "net ads join"? The crash also seems to indicate that the "secrets" bit of "secrets and keytab" is returning a null pointer to the code, so maybe samba isn't finding the secret. Do you have a populated /etc/krb5.keytab? Can you try these commands: net ads testjoin -k net ads status -k After having acquired a kerberos ticket most likely (for -k to work). -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/1761737 Title: [bionic] samba PANIC, INTERNAL ERROR: Signal 11 To manage notifications about this bug go to: https://bugs.launchpad.net/samba/+bug/1761737/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
