- # :TODO:31.08.2007:: was hat es mit dem "gotoSysStatus: $1" auf sich, was ist 
- # das und wie muss ich es einbauen? Siehe Skript gosa-dhcp-monitor Zeile 131. 
- # Dort hat es den Wert der IP-Adresse, in meinem Test-LDAP finde ich aber
- # gotoSysStatus nicht
-
- # :TODO:31.08.2007:: zu welchem Attribut im LDAP entry soll das Interface 
- # geschrieben werden? Siehe Funktion add_ldap_entry
-
- # :TODO:31.08.2007:: basename beim erzeugen von neuen entries noch 
- # base64-codieren, bei add_ldap_entry und change_ldap_entry, klären mit cajus
- # ist das überhaupt notwendig???
-
- # :TODO:31.08.2007:: könnte es sein, dass das Interface gar kein eigener Wert
- # ist, sondern zur description gehört???
-
- # :TODO:03.09.2007:: bei SIGHUP muss das logfile neu angelegt werden, nicht
- # einfach in dem alten weiterschreiben
