Public bug reported: It is not possible anymore to connect anonymously to a Samba server, if there is a Kerberos environment. It does not matter if there is a valid Kerberos ticket or not. I'm using FreeIPA.
This is with smbclient 2:4.11.6+dfsg-0ubuntu1.4 For example, $ smbclient -L '//dist.ghs.nl/space' -N Failed to resolve credential cache 'KEYRING:persistent:60001'! (Unknown credential cache type) free(): double free detected in tcache 2 Aborted (core dumped) On Ubuntu 18.04, with smbclient 2:4.7.6+dfsg~ubuntu-0ubuntu2.18 it works as expected (albeit with many messages about failing krb5_init_context and smb_krb5_context_init_basic) The combination Samba + FreeIPA + Ubuntu has never worked since I started using FreeIPA a few years ago. But anonymous access to a Samba server did work, until I switched to Ubuntu 20.04. ** Affects: samba (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892145 Title: smbclient cannot connect anonymously in Kerberos context (freeipa) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1892145/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
