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)
