Searching for EA with Inheritance State equals Overriden/No Parent [ Edited ]

[#1]

Hi,

We have an lot of networks in our Infoblox and I would like to find out on which of them an Extensible Attribute is set. In the webfrontend I can use the Quick Filter to select networks on which the "Inheritance State equals"  of this attribute is Overriden/No Parent.

I would like to the same in our python scripts which calls the API, but I can't find this in the WAPI documentation.

I have tried this but it does not work:

curl -n -k1 'https://infobloxacc.test/wapi/v2.7.3/netwrkcontainer' -X GET -d '_return_fields%2B=extattrs'  -d '*Administrative-Domain[inheritance_source]~='

{ "Error": "AdmConProtoError: Unknown extensible attribute: Administrative-Domain[inheritance_source]",
"code": "Client.Ibap.Proto",
"text": "Unknown extensible attribute: Administrative-Domain[inheritance_source]"

Does anyone have an idea how to do this?
