/**
Represents the authentication information and a set of connections to the IBM i host servers.
If running on IBM i or an older version of that operating system, the system name, user ID,
and password do not need to be supplied. These values default to the local system.
For the system name, the keyword localhost can be used to specify the local system.
For the user ID and password, *CURRENT can be used.
If running on another operating system, the system name, user ID, and password need to be supplied.
If not supplied, the first 'open' request associated with this object will trigger a prompt to the
workstation user. Subsequent opens associated with the same object will not prompt the workstation
user. Keywords localhost and *CURRENT will not work when running on another operating
system.
For example:
* AS400 system = new AS400();
* system.connectService(AS400.DATAQUEUE); // This causes a password prompt.
* ...
* system.connectService(AS400.FILE); // This does not cause a prompt.

Note: Providing an incorrect password increments the number of failed sign-on attempts for the user profile, and can result in the profile being disabled. Refer to documentation on the ProfileTokenCredential class for additional restrictions.
@param userId The user profile name.
@param password The user profile password.
@param tokenType The type of profile token to create. Possible types are defined as fields on the ProfileTokenCredential class:

- {@link com.ibm.as400.security.auth.ProfileTokenCredential#TYPE_MULTIPLE_USE_NON_RENEWABLE TYPE_MULTIPLE_USE_NON_RENEWABLE}
- {@link com.ibm.as400.security.auth.ProfileTokenCredential#TYPE_MULTIPLE_USE_RENEWABLE TYPE_MULTIPLE_USE_RENEWABLE}
@param timeoutInterval The number of seconds to expiration when the token is created (1-3600).
@return A ProfileTokenCredential representing the authenticated profile and password.
@exception AS400SecurityException If a security or authority error occurs.
@exception IOException If an error occurs while communicating with the system.
