Doing the above loop for every host change in LDAP will let the script walk over 300 LDAP queries. The response time of GOsa becomes awful with that.[..]During the next days, I can test your patch, either the one or above or a follow-up version.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.) Wolfgang
I looked at your script snippet and modified it and tested it on a live system with many hosts and LDAP being out-of-sync with the keytab files:
```
#!/bin/bash
set -e
declare -a hosts
num_hosts=0
while read KEY VALUE ; do
case "$KEY" in
dn:) let "num_hosts+=1" ;;
cn:) hosts[$(($num_hosts-1))]="$VALUE" ;;
"")
:
;;
esac
done < <(ldapsearch -xLLL "objectclass=dhcpHost")
# add gateway host manually
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 $(basename -a /etc/debian-edu/host-keytabs/* | sed
's#.intern.keytab##' | tr 'A-Z' 'a-z') ; do
if [[ ! "${hosts_str},," =~ ",,$i,," ]]; then
kadmin.local delprinc host/$i.intern@INTERN
kadmin.local delprinc nfs/$i.intern@INTERN
rm /etc/debian-edu/host-keytabs/$i.intern.keytab
fi
done
```
Changes:
* avoid the need of a TEMP file
* match LDAP hosts case insensitive
I wonder if this script (I tested it as a standalone script) should
not be better placed as a daily CRON job on TJENER (?) instead of it
being part of the gosa-modify-host hook script.
