-AuthType- Specifies the authentication method to use. The acceptable values for this parameter are: - Negotiate or 0 - Basic or 1 The default authentication method is Negotiate. A Secure Sockets Layer (SSL) connection is required for the Basic authentication method.
-ComplexityEnabled- Specifies whether password complexity is enabled for the password policy. If enabled, the password must contain three of the following four character types: - Uppercase characters (A, B, C, D, E, ...) - Lowercase characters (a, b, c, d, e, ...) - Numerals (0, 1, 2, 3, ...) - Special characters (#, $, *, %, ...) This parameter sets the ComplexityEnabled property of a password policy. The acceptable values for this parameter are: - $False or 0. Disables password complexity. - $True or 1. Enables password complexity.
-Confirm- Prompts you for confirmation before running the cmdlet.
-Credential- Specifies the user account credentials to use to perform this task. The default credentials are the credentials of the currently logged on user unless the cmdlet is run from an Active Directory module for Windows PowerShell provider drive. If the cmdlet is run from such a provider drive, the account associated with the drive is the default. To specify this parameter, you can type a user name, such as User1 or Domain01\User01 or you can specify a PSCredential object. If you specify a user name for this parameter, the cmdlet prompts for a password. You can also create a PSCredential object by using a script or by using the Get-Credential cmdlet. You can then set the *Credential* parameter to the PSCredential object. If the acting credentials do not have directory-level permission to perform the task, Active Directory module for Windows PowerShell returns a terminating error.
-Description- Specifies a description of the object. This parameter sets the value of the Description property for the object. The Lightweight Directory Access Protocol (LDAP) display name (ldapDisplayName) for this property is description.
-DisplayName- Specifies the display name of the object. This parameter sets the DisplayName property of the object. The LDAP display name (ldapDisplayName) for this property is displayName.
-Instance- Specifies an instance of a fine-grained password policy object to use as a template for a new fine-grained password policy object. You can use an instance of an existing fine-grained password policy object as a template or you can construct a new fine-grained password policy object by using the Windows PowerShell command line or by using a script. Method 1: Use an existing fine-grained password policy object as a template for a new object. To retrieve an instance of an existing fine-grained password policy object, use a cmdlet such as Get-ADFineGrainedPasswordPolicy. Then provide this object to the *Instance* parameter of the New-ADFineGrainedPasswordPolicy cmdlet to create a new fine-grained password policy object. You can override property values of the new object by setting the appropriate parameters. Method 2: Create a new ADFineGrainedPasswordPolicy object and set the property values by using the Windows PowerShell command line interface. Then pass this object to the *Instance* parameter of the New-ADFineGrainedPasswordPolicy cmdlet to create the new Active Directory fine-grained password policy object. Note: Specified attributes are not validated, so attempting to set attributes that do not exist or cannot be set will raise an error.
-LockoutDuration- Specifies the length of time that an account is locked after the number of failed login attempts exceeds the lockout threshold. You cannot log in to an account that is locked until the lockout duration time period has expired. If you set the value to 0 the account needs to be unlocked manually by the administrator. This parameter sets the lockoutDuration property of a password policy object. The LDAP display name (ldapDisplayName) of this property is msDS-LockoutDuration. The lockout duration must be greater than or equal to the lockout observation time for a password policy. Use the *LockOutObservationWindow* parameter to set the lockout observation time. Specify the lockout duration time interval in the following format: D.H:M:S.F where: - D = Days (0 to 10675199) - H = Hours (0 to 23) - M = Minutes (0 to 59) - S = Seconds (0 to 59) - F= Fractions of a second (0 to 9999999)
-LockoutObservationWindow- Specifies the maximum time interval between two unsuccessful login attempts before the number of unsuccessful login attempts is reset to 0. An account is locked when the number of unsuccessful login attempts exceeds the password policy lockout threshold. This parameter sets the lockoutObservationWindow property of a password policy object. The LDAP display name (ldapDisplayName) of this property is msDS-lockoutObservationWindow. The lockout observation window must be smaller than or equal to the lockout duration for a password policy. Use the *LockoutDuration* parameter to set the lockout duration time. > [!NOTE] > Setting the lockout observation window to 0 effectively means that the window is too short to > observe more than one password attempt, therefore the account will never be locked out. Specify the time interval in the following format: D:H:M:S.F where: - D = Days (0 to 10675199) - H = Hours (0 to 23) - M = Minutes (0 to 59) - S = Seconds (0 to 59) - F= Fractions of a second (0 to 9999999) Note: Time values must be between the following values: 0:0:0:0.0 and 10675199:02:48:05.4775807.
-LockoutThreshold- Specifies the number of unsuccessful login attempts that are permitted before an account is locked out. This number increases when the time between unsuccessful login attempts is less than the time specified for the lockout observation time window. This parameter sets the LockoutThreshold property of a password policy.
-MaxPasswordAge- Specifies the maximum length of time that you can have the same password. After this time period, the password expires and you must create a new one. This parameter sets the maxPasswordAge property of a password policy. The LDAP display name (ldapDisplayName) for this property is maxPwdAge. Specify the time interval in the following format: D.H:M:S.F where: - D = Days (0 to 10675199) - H = Hours (0 to 23) - M = Minutes (0 to 59) - S = Seconds (0 to 59) - F= Fractions of a second (0 to 9999999) Note: Time values must be between the following values: 0 and 10675199:02:48:05.4775807.
-MinPasswordAge- Specifies the minimum length of time before you can change a password. This parameter sets the minPasswordAge property of a password policy. The LDAP display name (ldapDisplayName) for this property is minPwdAge. Specify the time interval in the following format: D.H:M:S.F where: - D = Days (0 to 10675199) - H = Hours (0 to 23) - M = Minutes (0 to 59) - S = Seconds (0 to 59) - F= Fractions of a second (0 to 9999999) Note: Time values must be between the following values: 0 and 10675199:02:48:05.
-MinPasswordLength- Specifies the minimum number of characters that a password must contain. This parameter sets the MinPasswordLength property of the password policy.
-Name (required)- Specifies the name of the object. This parameter sets the Name property of the Active Directory object. The LDAP display name (ldapDisplayName) of this property is name.
-OtherAttributes- Specifies object attribute values for attributes that are not represented by cmdlet parameters. You can set one or more parameters at the same time with this parameter. If an attribute takes more than one value, you can assign multiple values. To identify an attribute, specify the LDAPDisplayName (ldapDisplayName) defined for it in the Active Directory schema. Syntax: To specify a single value for an attribute: -OtherAttributes @{'AttributeLDAPDisplayName'=value} To specify multiple values for an attribute -OtherAttributes @{'AttributeLDAPDisplayName'=value1,value2,...} You can specify values for more than one attribute by using semicolons to separate attributes. The following syntax shows how to set values for multiple attributes: -OtherAttributes @{'Attribute1LDAPDisplayName'=value; 'Attribute2LDAPDisplayName'=value1,value2;...}
-PassThru- Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-PasswordHistoryCount- Specifies the number of previous passwords to save. A user cannot reuse a password in the list of saved passwords. This parameter sets the PasswordHistoryCount property for a password policy.
-Precedence (required)- Specifies a value that defines the precedence of a fine-grained password policy among all fine-grained password policies. This parameter sets the Precedence property for a fine-grained password policy. The LDAP display name (ldapDisplayName) for this property is msDS-PasswordSettingsPrecedence. This value determines which password policy to use when more than one password policy applies to a user or group. When there is a conflict, the password policy that has the lower Precedence property value has higher priority. For example, if PasswordPolicy1 has a Precedence property value of 200 and PasswordPolicy2 has a Precedence property value of 100, PasswordPolicy2 is used. Typically, password policy precedence values are assigned in multiples of 10 or 100, making it easier to add policies at a later time. For example, if you set the initial precedence values for your policies to 100 and 200, you can add another policy that has precedence value of 150. If the specified *Precedence* parameter is already assigned to another password policy object, the cmdlet returns a terminating error.
-ProtectedFromAccidentalDeletion- Specifies whether to prevent the object from being deleted. When this property is set to true, you cannot delete the corresponding object without changing the value of the property. The acceptable values for this parameter are: - $False or 0 - $True or 1
-ReversibleEncryptionEnabled- Specifies whether the directory must store passwords using reversible encryption. This parameter sets the ReversibleEncryption property for a password policy. The acceptable values for this parameter are: - $False or 0 - $True or 1
-Server- Specifies the Active Directory Domain Services instance to connect to, by providing one of the following values for a corresponding domain name or directory server. The service may be any of the following: Active Directory Lightweight Domain Services, Active Directory Domain Services, or Active Directory snapshot instance. Specify the Active Directory Domain Services instance in one of the following ways: Domain name values: - Fully qualified domain name - NetBIOS name Directory server values: - Fully qualified directory server name - NetBIOS name - Fully qualified directory server name and port The default value for this parameter is determined by one of the following methods in the order that they are listed: - By using the *Server* value from objects passed through the pipeline - By using the server information associated with the Active Directory Domain Services Windows PowerShell provider drive, when the cmdlet runs in that drive - By using the domain of the computer running Windows PowerShell
-WhatIf- Shows what would happen if the cmdlet runs. The cmdlet is not run.
