Microsoft ad complex passwords

Archived Forums. Directory Services. Sign in to vote. Hello, We need to enable complex password in our small organization. Our AD is in Monday, August 21, AM. Hi, To enable force password change user -mustchpwd with dsquery. If you need further help, please feel free to let us know. Best Regards, William. Submit ». This page has the best I could find, I know there are some that will cause AD to freak out. Coloradogeek This person is a verified professional.

The samAccountName is checked in its entirety only to determine whether it's part of the password. If the samAccountName is fewer than three characters long, this check is skipped. The displayName is parsed for delimiters: commas, periods, dashes or hyphens, underscores, spaces, pound signs, and tabs.

If any of these delimiters are found, the displayName is split and all parsed sections tokens are confirmed not to be included in the password. Tokens that are shorter than three characters are ignored, and substrings of the tokens aren't checked. For example, the name "Erin M. Hagens" is split into three tokens: "Erin", "M", and "Hagens".

Because the second token is only one character long, it's ignored. So, this user could not have a password that included either "erin" or "hagens" as a substring anywhere in the password. The rules that are included in the Windows Server password complexity requirements are part of Passfilt. When enabled, the default Passfilt. But this policy setting is liberal enough that all users should get used to it. Additional settings that can be included in a custom Passfilt.

To type upper-row characters, you hold the SHIFT key and press one of any of the keys on the number row of the keyboard from 1 through 9 and 0.

Be especially cautious about using extended ANSI characters in passwords if your organization uses several different operating systems. For example, these systems may standardize in ISO A passphrase is a different form of token-based password in which the tokens are words instead of symbols from a character set.

An example of a passphrase is a sentence that contains special characters, numerals, uppercase letters, and lowercase letters. The key differences between passphrases and passwords are:. Passphrases that conform to the character limit as set in the policy are generally, more difficult to crack than passwords because they contain more characters.

There are several ways to ensure the LM hash is not stored; one of them is to use passwords or passphrases longer than 14 characters. Using this policy setting globally turns off storage LM hashes for all accounts. The change will take effect the next time the password is changed. Because the policy's effect is not immediate, you will not immediately notice any potential interoperability problems caused by not storing LM hashes.

You can implement a password policy setting that enforces password complexity requirements. For more information about this policy setting, see Password must meet complexity requirements. For information about how to apply a password policy, see Apply or Modify a Password Policy.

For information about all available password policy settings, see Password Policy. Beginning with Windows Server , you can use fine-grained password policies to specify multiple password policies and apply different password restrictions and account lockout policies to different sets of users within a single domain. For example, to increase the security of privileged accounts, you can apply stricter settings to the privileged accounts and then apply less strict settings to the accounts of other users.

Or in some cases, you may want to apply a special password policy for accounts whose passwords are synchronized with other data sources. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info. Contents Exit focus mode.
