Inheritance means that certain properties or attributes of a higher-level entry are automatically passed down to lower-level entries that inherit from it. This can be useful to set default attributes or even simplify management by only having to make changes at the inherited-level entry.
Inheritance is accessible by going into Properties – Common – General – Credentials and selecting Inherited.
If the credentials of the parent are not inherited properly, it indicates that one of the levels is not set to Inherited.
