You must create an entry for the user in the Sign-on Table (SNT) if the user requires: 
	 
 
	  
		- A user ID and password. These are required if: 
		  
 
			 -  The user has to sign on to 
				MSS using the supplied transaction CESN. 
			 
 
 
			 - The user wants to modify resource definitions using the Resource Definition Facility if security is enabled.
			 
 
 
		  
		 
 
		- Security keys 
		   and/or resource keys.
		
 
 
	 
 
	 Each entry in the SNT specifies the following: 
	 
 
	  
		- The ID with which a user signs on through the CESN transaction. 
		
 
 
		- The user's 
		  MSS password. 
		
 
 
		- The user's security and resource keys.
