> As reported by [~dian.fu] :
> Key based ACL in KMS is currently implemented as whitelist. So if I configure as follows in kms-acl.xml,
> {code}
>  <property>
>     <name>key.acl.testKey.DECRYPT_EEK</name>
>     <value>testUser</value>
>   </property>
> {code}, then only {{testUser}} user can do {{DECRYPT_EEK}} call on key {{testKey}}. If I want {{yarn}} user can also do {{DECRYPT_EEK}} call on {{testKey}} key, I need add {{yarn}} user to the above configuration value manually. This means that if I want to configure key based ACL({{DECRYPT_EEK}}) for {{some key}}, I need also add {{yarn}} user to configuration {{DECRYPT_EEK}} for that key. As I don't know if {{yarn}} user will later need to do {{DECRYPT_EEK}} for this key.. This is inconvenient and tricky.
> This can be alleviated by slightly modifying the key ACL logic in KMS first checks if the user, in this case {{yarn}}, is present in {{key.acl.<key-name>.<OP-name>}} list. And if not, then also check if the user is present in {{default.key.acl.<OP-name>}}. If yes, then grant access.. else deny.
> Currently,  {{default.key.acl.<OP-name>}} is consulted only if NO {{key.acl.<key-name>.<OP-name>}} is specified.
