AS400/IBMi Rules

These rules should be used for AS400/IBMi Password generation -- please see:

https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_73/rzakz/rzakzpwrules.htm (if link is obsolete just search on "AS400 Password Rules")

Note that a secure randomization algorithm is employed at all distributions and assignment of character type positions.

AS400/IBMi Example: pwLength:10;norepeatchars:true;digitsMin:2;alphaMin:2;specialMin:2;specialMax:2;mixedCase;noAdjDigits;

Rule Name	Type	Reference	Description
MixedCase	Boolean	Password Level 2, MIXCASEn	Set TRUE in order to include lower case alpha/letter characters
RestrictedChars	String	QPWDLMTCHR	Provide a list of restricted characters--note that the semicolon cannot be restricted but this can be achieved using the SetPasswordSpecialChars setting.
NoRepeatChars	Boolean	CHRLMTREP, QPWDLMTREP	No character can be used more than once in the password
NoAdjChars	Boolean	CHRLMTAJC	No character can be adjacent to the same character (no 2 in a row)
AlphaMin	Integer	LTRMINn	Minimum number of alphabetic characters in the password - cannot be greater than either AlphaMax or the length of the password.
AlphaMax	Integer	LTRMAXn	Maximum number of alphabetic characters in the password--cannot be greater than the length of the password or less than the AlphaMin rule.
NoAdjAlpha	Boolean	LTRLMTAJC	No alphabetic characters can be adjacent to each other / consecutive-- no two in a row.
DigitsMin	Integer	DGTMINn, QPWDRQDDGT	Minimum number of numeric characters (digits) in the password - cannot be greater than either DigitsMax or the length of the password.
DigitsMax	Integer	DGTMAXn	Maximum number of numeric characters (digits) in the password--cannot be greater than the length of the password or less than the DigitsMin rule.
NoAdjDigit	Boolean	DGTLMTAJC, QPWDLMTAJC	No numeric characters (digits) can be adjacent to each other / consecutive-- no two in a row.
NoSpecialChars	Boolean	SPCMAX0	No Special characters included anywhere in the password--same as SpecialMax:0
SpecialMin	Integer	SPCMINn	Minimum number of special characters in the password - cannot be greater than either SpecialMax or the length of the password.
SpecialMax	Integer	SPCMAXn	Maximum number of special characters in the password--cannot be greater than the length of the password or less than the SpecialMin rule.
NoAdjSpecial	Boolean	SPCLMTAJC	No special characters can be adjacent to each other / consecutive-- no two in a row.
FirstNotDigit	Boolean	DGTLMTFST	First character cannot be a numeric digit
FirstNotAlpha	Boolean	LTRLMTFST	First character cannot be a alphabetic character / letter
FirstNotSpecial	Boolean	SPCCHRLMTFST	First character cannot be a special character
LastNotDigit	Boolean	DGTLMTLST	Last character cannot be a numeric digit
LastNotAlpha	Boolean	LTRLMTLST	Last character cannot be a alphabetic character / letter
LastNotSpecial	Boolean	SPCCHRLMTLST	Last character cannot be a special character
(always true)	Boolean	LMTSAMPOS, QPWDPOSDIF	No characters in a generated password will include a character that matches the character in the same position as the previous password. Note that this requires no "new" passwords are generated, only replacement for passwords already known. If a password is not known than this setting is ignored.
