Informix - Problem description

Problem IT38317 Status: Closed

TRUSTED CONTEXT USER IS NOT ABLE TO CONNECT WITHOUT AUTHENTICATION

product:
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problem description:
When using trusted connections and a trusted-context object a
user may be authorized for use without authentication. An
example:

CREATE TRUSTED CONTEXT tc1
BASED UPON CONNECTION USING SYSTEM AUTHID 'user1'
ATTRIBUTES (ADDRESS 'host1')
WITH USE FOR user2 WITHOUT AUTHENTICATION
DEFAULT ROLE testrole
ENABLE ;

In this example user1 establishes a trusted connection to the
Informix server and should then be able to switch to the user2
without having to provide user2's password. However this
operation fails and error -26456 "The authorization ID 
is not defined for the trusted context" is returned.

If the trusted context object is created WITH AUTHENTICATION for
user2 then the switch user operation will succeed when a valid
password is provided.
