heimdal-kcm 7.4.0.dfsg.1-2 (s390x binary) in ubuntu artful

 Heimdal is a free implementation of Kerberos 5 that aims to be
 compatible with MIT Kerberos.
 .
 This package includes the KCM daemon which can hold the credentials
 for all users in the system. Access control is done with Unix-like
 permissions. The daemon checks the access on all operations based on
 the UID and GID of the user. The tickets are renewed as long as is
 permitted by the KDC's policy.
