[Samba] coredump while loggin in on SSH with a user ( with UID )
Hai, i've seen a core dump... ? Clean server, static ip, Debian Jessie, samba 4.1.13 and cups installed. ? Im leaving the office now, but ill go test tomorrow some more. It happend while logging in on ssh server. pretty basic setup, like on the wiki, and?pam was updated by running pam-auth-update. tomorrow more info if this is not known. ?
