A newly created security definition has a password set to a random UUID4 and needs to be changed in order to be usable.
Updates a definition’s password - the password is stored in the ODB along with other details of a security definition. This is not a required field and the password can be omitted altogether if it’s not needed at all.
Deletes a security definition and all the connections that make use of it.
It needs to be emphasized that any plain HTTP or SOAP channels and outgoing connections that were using the definition will also be deleted automatically.
