##### SUMMARY

##### STEPS TO REPRODUCE

~~~
1. Make sure your ROOT domain has a DomainAdmin account.
2. Pick one of the VM templates on a running Cloudstack platform to test the API call on
3. Run the following command under the RootAdmin: `cmk list templates templatefilter=executable filter=id,name keyword=`
4. Run the same command under the DomainAdmin.
~~~

##### EXPECTED RESULTS

When running the command under **RootAdmin**, the result template entries match the "count" JSON field:
~~~
cmk list templates templatefilter=executable filter=id,name keyword=MyTemplate
{
"count": 5,
"template": [
{
"id": "19c1af19-ca5a-4f1d-aece-d253f3e961c2",
"name": "MyTemplate 1"
},
{
"id": "804558dd-cc80-4e13-a67d-0db607930fc4",
"name": "MyTemplate 2"
},
{
"id": "7fc10cc1-34e6-46b2-b699-8369b4cc031b",
"name": "MyTemplate 3"
},
{
"id": "7f6504f5-b5ae-437f-99a5-4ca814e41157",
"name": "MyTemplate 4"
},
{
"id": "bf338572-85df-46aa-b4d6-678edd865c5e",
"name": "MyTemplate 5"
}
]
}
~~~

##### ACTUAL RESULTS

When running the command under **DomainAdmin**, the result template entries **do not** match the "count" JSON field:
~~~
cmk list templates templatefilter=executable filter=id,name keyword=MyTemplate
{
"count": 20,
"template": [
{
"id": "19c1af19-ca5a-4f1d-aece-d253f3e961c2",
"name": "MyTemplate 1"
},
{
"id": "804558dd-cc80-4e13-a67d-0db607930fc4",
"name": "MyTemplate 2"
},
{
"id": "7fc10cc1-34e6-46b2-b699-8369b4cc031b",
"name": "MyTemplate 3"
},
{
"id": "7f6504f5-b5ae-437f-99a5-4ca814e41157",
"name": "MyTemplate 4"
},
{
"id": "bf338572-85df-46aa-b4d6-678edd865c5e",
"name": "MyTemplate 5"
}
]
}

Comece reproduzindo a solicitação listTemplates com templatefilter=executable, filter=id,name e uma palavra-chave tanto em RootAdmin quanto em DomainAdmin. Compare o campo count com as entradas de template retornadas e rastreie o tratamento da API para a visibilidade de templates específica de cada função; está concluído quando ambas as funções relatarem um count correspondente às suas entradas retornadas.
