Comment 7 for bug 1783183

I used this for now:
root@bionic-slapd-consumer:/etc/apparmor.d# cat local/usr.sbin.slapd
# Site-specific additions and overrides for usr.sbin.slapd.
# For more details, please see /etc/apparmor.d/local/README.

  /etc/krb5/user/[0-9]*/client.keytab rk,
  /tmp/krb5cc_[0-9]* rwk,

I'm checking if there is some apparmor macro or variable we could use for something like "my own uid"
