Hi. I'm twsting ubuntu 20.04 in freeipa domain with smbclient.

In some cases it works (fresh installation of xubuntu, for example), in other - dont (upgrade kubuntu from 18.04).

 

Failed to resolve credential cache 'KEYRING:persistent:15000'! (Unknown credential cache type)
free(): double free detected in tcache 2
Аварийный останов (стек памяти сброшен на диск)
 

In first case i have ticket:

Ticket cache: FILE:/tmp/krb5cc_15000
Default principal: myname@mydomain

Valid starting       Expires              Service principal
03.08.2020 11:00:23  04.08.2020 11:00:20  krbtgt/
 

In second:

 

Why?

 

I have

#default_ccache_name = KEYRING:persistent:%{uid}
in krb5.conf
