Maybe you can test a follow-up one, based on your proposal to query LDAP only once. (Host gateway considered too, just in case someone has added a keytab.)
Here is a slight change...

hosts[$num_hosts]=gateway
# and also tjener...
hosts[$num_hosts+1]=tjener
printf -v hosts_str -- ',,%q' "${hosts[@]}"
hosts_str=$(echo $hosts_str | tr 'A-Z' 'a-z')
for i in $(basename -a /etc/debian-edu/host-keytabs/* | sed

if [[ ! "${hosts_str},," =~ ",,${match_value},," ]]; then
kadmin.local delprinc host/$i.intern@INTERN
kadmin.local delprinc nfs/$i.intern@INTERN

The match_value part in the loop got introduced. We need to keep the
case-sensitive string for exactly matching the file name and the
principal name. But for matching, we want all to be lower-case.
