Bug#1020442: heimdal breaks openldap autopkgtest: test smbk5pwd

[Ryan Tandy]

Thanks for raising the bug. The slapd autopkgtest does a chgrp/chmod to 
grant slapd access to the heimdal master key, but the permissions on the 
containing directory (/var/lib/heimdal-kdc) became more restrictive (now 
700). I will update the autopkgtest ASAP.
