[Samba] FW: coredump while loggin in on SSH with a user ( with UID )

Fri Nov 14 00:58:50 MST 2014

If anyone want the below dump its reproduceable, so i looks to my this is a bug
and simply fixed.

I didnt set the kerberos settings in sshd_config:
so i enabled. 
KerberosAuthentication yes
KerberosGetAFSToken no
KerberosOrLocalPasswd yes
KerberosTicketCleanup yes

and the crash is gone. 

greetz,

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.
