I use Kerberos for my home network. However, every time I run the testsuite it ends up overwriting my local credentials cache.
Once I run 'make test', klist starts returning:
Credentials cache: FILE:/tmp/krb5cc_1000
Issued Expires Principal

Fixed in f09f5ae631c64da016072b1c09c172f4673a06cd in master for Samba 4.6.
(also attempted to be fixed many times previously).
