This parameter also sets the ADS_UF_ENCRYPTED_TEXT_PASSWORD_ALLOWED flag of the Active Directory User Account Control (UAC) attribute. .PARAMETER CompoundIdentitySupported Specifies whether an account supports Kerberos service tickets which includes the authorization data for the user's device. This value sets the compound identity supported flag of the Active Directory msDS-SupportedEncryptionTypes attribute. .PARAMETER PasswordNotRequired Specifies whether the account requires a password. A password is not required for a new account. This parameter sets the PasswordNotRequired property of an account object. .PARAMETER SmartcardLogonRequired Specifies whether a smart card is required to logon. This parameter sets the SmartCardLoginRequired property for a user object. This parameter also sets the ADS_UF_SMARTCARD_REQUIRED flag of the Active Directory User Account Control attribute. .PARAMETER DomainController Specifies the Active Directory Domain Services instance to use to perform the task. .PARAMETER Credential Specifies the user account credentials to use to perform this task. .PARAMETER PasswordAuthentication Specifies the authentication context type used when testing passwords.
