• usrmod0_min_passwd_len is the minimum password length. The range of values is 0 to MAX_PASSWD_LEN.

• usrmod0_max_passwd_age is the maximum time (in seconds) since the password was last changed and for which the current password is valid. A value of 0xFFFFFFFF (TIMEQ_FOREVER) allows the password to be valid forever. The minimum value is 1 day.

• usrmod0_min_passwd_age is the minimum time (in seconds) since the password was last changed and before which the current password is allowed to be changed. A value of 0 means no delay is required between password updates.

• usrmod0_force_logoff is the length of time (in seconds) after the valid logon hours that the user should be forced off the network. If the value is TIMEQ_FOREVER (0xFFFFFFFF), the user is never forced off. If the value is 0, the user is forced off immediately. Any value between these also can be used.

• usrmod0_password_hist_len is the length of the password history (that is, the number of passwords in the history buffer that are scanned as opposed to the new password in a NetUserPasswordSet attempt). The new password must not match any of the entries scanned. The history is of encrypted passwords. It can be set from 0 to DEF_MAX_PWHIST (currently 8).

• usrmod0_maxbadpw restricts the number of bad password attempts. A value of 0 sets no limits. This parameter is not supported in DSS.
