The login type determines what happens when the application establishes a connection to
the platform and another session is currently active.
There are three valid login types:
py1010.POSSESS,
py1010.KILL, and
py1010.NOKILL.
- py1010.POSSESS attaches the new login to an existing session if one is
active when the connection is established.
- py1010.KILL ends an existing session and starts a new one when the
connection is established.
- py1010.NOKILL fails to connect if an existing session is active when the
connection is established.
If no session is active, a new session is started.
