Defining A CICS Default User 

CICS Release 3.2.1 and above require the definition of a default user. This 
userid is used for all security checking done before anyone signs onto a terminal. It is specified 
in the CICS SIT parameter DFLTUSER. 
The userid coded must be a valid ACID and have access to the CICS facility. 
If the ACID is not properly defined or suspended, CICS will fail to initialize. 
It is recommended that the ACID used be given limited authority to reduce the potential for 
misuse. 
In addition, the ACID should be given the NOSUS (no suspend) attribute, to keep it from being suspended.
