Bug 743253

additional information :

# ipa hostgroup-find
ipa: ERROR: The search criteria was not specific enough. Expected 1 and found 2.

# ipa netgroup-del test
ipa: ERROR: The search criteria was not specific enough. Expected 1 and found 2.

Fixed upstream:
master: a85bb7fa9e5a03b391d684e2850bfe4663f94e21
ipa-2-1: 92dbd68677b3166ebb8897c5fac7d6a142226ac1

This fix is causing a regression :

Should be checking to see if a duplicate hostgroup exists first and then check for a netgroup - only if Netgroup Plugin is enabled.

ipa-server-2.1.2-100.20111014T0057zgit16fc9f8.el6.x86_64

Fixed upstream:
master: https://fedorahosted.org/freeipa/changeset/99d938152fbef41f2d48d4088e5ba39bc820e9de
ipa-2-1: https://fedorahosted.org/freeipa/changeset/5a3268fc7d731232844eb9391be722db2179f24c

Just a note: The netgroup/hostgroup collision checks are run in all cases, we don't test if netgroup plugin is enabled/disabled.

This is a precausion. If user enables the plugin again, he would get into trouble if he had colliding hostgroups/netgroups. We wanted to play on the safe side here.

    New Contents:
Cause: Due to compatibility with NIS when a hostgroup is added, a netgroup with the same name is added. However, when the hostgroup is created, it is not checked if there is not a netgroup with the same name already which may have been added separately (without a hostgroup).
Consequence: Hostgroup is created but the netgroup cannot be added and user is not notified about this event. This can lead to unexpected and surprising behavior.
Fix: When a hostgroup is added, IPA server checks first if the netgroup name is free and refuses to add hostgroup otherwise
Result: New hostgroups cannot get into conflict with existing netgroups.
