Two types of global password policies exist: Disable Login controls when accounts are able to log in, and Passwords Must controls various requirements for a password to be allowed. We strongly recommend using as many of these as possible, because they provide a substantial amount of Open Directory security. However, keep in mind that the harder a password is for a user to remember, the more likely they are to write it down, so a certain amount of balance between complexity and ease of remembrance should be practiced here. Let s briefly discuss each: Disable Login Passwords: Allows logins to be disabled when the following criteria are met (per policy choice in Server Admin): On specific date: Disables the account on a set date. Disabling accounts that could still be active can be an administrative burden, but it can be helpful for environments with a large number of temporary or freelance users. After using it for: Disables new accounts after they have been active for a determined number of days. After inactive for: Disables new accounts after they are dormant for a definable number of days. For most environments, a number between 7 and 30 is a suitable amount of inactivity for an account before it should be considered dead. This option helps for environments where the sheer number of accounts makes it difficult to keep track of account activity. After user makes ___ failed attempts: Disables accounts after a definable number of failed attempts have occurred. For most environments, a number between 3 and 10 is a suitable number of failed attempts. Passwords Must: Allows password policies to be made, including the following: Differ from account name: This option keeps the password from being identical to the username. Contain at least a letter: This option forces an account to have at least one character from the alphabet (a to z) in the password. This enforces a policy that avoids passwords such as 1234. Contain both uppercase and lowercase letters: This option requires at least one letter be uppercase and at least one letter be lowercase. Passwords are case sensitive. Contain at least a number: This option forces a password to have a number in it. An example of an allowable password would be 1paSsworD1. Passwords should typically have at least one lowercase letter, at least one uppercase letter, and at least one numeric character.

Be reset on first login: This is a good option for new accounts or accounts that have had their passwords reset. This will keep administrators from knowing their users passwords (a policy that protects the administrator as well as the user). This will provide a certain level of comfort to users that the administrator is not snooping through their personal data. If you need access to an account, then you should be forced to reset a password to obtain it. Contain at least: This option allows you to define the minimum length of a password in characters. The minimum length of a password is something debatable in any environment. For many, eight is a good number, but this is not as much a technical decision as it is a management decision. Differ from last: This option allows you to force users to change their passwords to something different every time they change their password for as many times as you specify. Some administrator s think 3 is enough, others say 18 is better. This is a decision that should be made on a management level in many cases. Be reset every: This option allows you to force your users to change passwords at specific times and to define the number of days, weeks, or months that can transpire before a new password must be set. Passwords should also be changed as often as management will allow.
