IIAUT (8-byte character string)

RACF password or passticket.

This is optional; if specified, it is used with the user ID in the MQMD security context to build a Utoken that is sent to IMS to provide a security context. If it is not specified, the user ID is used without verification. This depends on the setting of the RACF switches, which may require an authenticator to be present.

This is ignored if the first byte is blank or null. The following special value may be used:

IAUNON

No authentication.

The length of this field is given by LNAUTH. The initial value of this field is IAUNON.
