When you establish a user connection, the logical server context of the connection is automatically determined by the user’s login policy and the current node:
When effective logical server assignment of the user's login policy is one or more logical servers, the logical server context of the connection is based on the current node's unambiguous membership into one of the specified logical servers.
A connection fails if the current node is not a member of any of the logical servers assigned to the user’s login policy.
A connection fails if effective logical server assignment of user's login policy is SERVER logical server and user does not have sufficient authority.
A connection also fails if logical server assignment for the user’s login policy is NONE.
