Description Wolf Wiegand univentionstaff 2007-02-27 13:11:28 CET 
Siehe dazu auch #3595 und #5694:

Für einen DHCP-Service wird unter [Erlauben/Verbieten] "Duplikate: allow" gesetzt. Dies führt zu Fehlern bei DHCP-Pool-Definitionen (siehe http://forum.univention.de/viewtopic.php?p=416). Dies lässt sich jedoch nicht dadurch korrigieren, indem für das Pool- bzw. für das Subnetz-Objekt eine Richtlinie definiert wird, in dem das Attribut mit leerem Wert vererbt werden soll. In diesem Fall wird 'duplicates' ohne allow/deny in die Konfiguration geschrieben:

Comment 2 Philipp Hahn univentionstaff 2013-11-08 16:29:26 CET 

In isc-dhcp/3.1-0-0-ucs/4.1.1-P1-15+squeeze6/51_dhcp_policy.patch the function univention_parse_policies() filters out such illegal statements since UCS-3.1.

For CONTEXT_POOL univentionDhcpDuplicates has been disabled and is no longer sent.

During PT for UCS-3.2 no such error was encountered.

All other such cases will be handled through Bug #20222.
