Password system values

In addition to setting signon system values, you also need to decide rules regarding users passwords

Password system values allow you to customize password rules that fit with your overall security environment. In general these values support the basic password requirements that you have documented in your security policy. The following information provides information on each of these system values:

• Set password rules
  Follow these steps to secure your system signon.
• Password level
  This system value allows you to set a specific password environment where all user profile passwords can have the same length specification.
• Password expiration interval
  The password expiration interval system value controls the number of days allowed before a password must be changed.
• Minimum length of passwords
  This system value controls the minimum number of characters in a password.
• Maximum length of passwords
  This system value controls the maximum number of characters in a password.
• Restrict duplicate passwords
  This system value controls whether the password must be different from previous passwords.
• Restricted characters for passwords
  This system value limits the use of certain characters in a password.
• Restrict consecutive digits in passwords
  This system value limits the use of numeric characters next to each other (adjacent) in a password.
• Limit repeating characters in passwords
  This system value limits the use of repeating characters in a password.
• Require different characters in each position in the password
  This system value controls the position of each character in a new password.
• Require a numeric character in passwords

• Store password information
  To support some network functions and communications requirements, iSeries™ servers provide a secure method for storing passwords that can be decrypted. Your system uses these passwords, for example, to establish a SLIP connection with another system.
• Password validation program
  This system value provides the ability for a user-written program to do additional validation on passwords.
