{ [-fields <fieldname>,…​]

If you specify the -fields parameter, the command only displays the fields that you specify.

| [-instance ] }

If you specify the -instance parameter, the command displays detailed information about all fields.

If this parameter is specified, the command displays information only about the security settings that match the specified KDC IP address.

[-kdc-name <text>,…​] - KDC Name

If this parameter is specified, the command displays information only about the security settings that match the specified KDC name.

[-site <text>,…​] - KDC Site

If this parameter is specified, the command displays information only about the security settings that match the specified Windows site.

[-is-signing-required {true|false}] - Require Signing for Incoming CIFS Traffic

This parameter specifies whether signing is required for incoming CIFS traffic. If this parameter is specified, the command displays information only about the security settings that match the specified value for is-signing-required.

[-is-password-complexity-required {true|false}] - Require Password Complexity for Local User Accounts

If this parameter is set to true , the command displays CIFS security configuration information only for CIFS servers where password complexity for local user accounts is required. If set to false , the command displays security configuration information for CIFS servers where password complexity for local user accounts is not required.

[-use-start-tls-for-ad-ldap {true|false}] - Use start_tls for AD LDAP Connections

If this parameter is set to true , the command displays CIFS security configuration information only for CIFS servers where Start TLS is used for communication with the AD LDAP Server. If set to false , the command displays CIFS security configuration information only for CIFS servers where Start TLS is not used for communication with the AD LDAP Server.

[-is-aes-encryption-enabled {true|false}] - (DEPRECATED)-Is AES-128 and AES-256 Encryption for Kerberos Enabled

If this parameter is set to true , the command displays CIFS security configuration information only for CIFS servers where AES-128 and AES-256 encryption types for Kerberos are enabled. If set to false , the command displays security configuration information for CIFS servers where AES-128 and AES-256 encryption types for Kerberos are disabled.

Note This parameter is deprecated and may be removed from a future release.
[-lm-compatibility-level {lm-ntlm-ntlmv2-krb|ntlm-ntlmv2-krb|ntlmv2-krb|krb}] - LM Compatibility Level

[-is-smb-encryption-required {true|false}] - Require SMB Encryption for Incoming CIFS Traffic

If this parameter is set to true , the command displays CIFS security configuration information only for CIFS servers where SMB encryption is required. If set to false , the command displays security configuration information for CIFS servers where SMB encryption is not required.

[-session-security-for-ad-ldap {none|sign|seal}] - Client Session Security

If this parameter is set to seal , the command displays CIFS security configuration information only for CIFS servers where both signing and sealing are required for LDAP communications. If set to sign , the command displays security configuration information for CIFS servers where only signing is required for LDAP communications. If set to none , the command displays security configuration information for CIFS servers where no security is required for LDAP communications.

[-smb1-enabled-for-dc-connections {false|true|system-default}] - (DEPRECATED)-SMB1 Enabled for DC Connections

If this parameter is set to true , the command displays CIFS security configuration information only for CIFS servers where SMB1 is enabled for use with connections to domain controllers. If set to false , the command displays security configuration information for CIFS servers where SMB1 is not enabled for use with connections to domain controllers. If set to system-default , the command displays security configuration information for CIFS servers where the system-default setting (SMB1 enabled) is used for connections to domain controllers.

Note This parameter is deprecated because the SMB1 protocol is obsolete and considered insecure. It might be removed in a future release.
[-smb2-enabled-for-dc-connections {false|true|system-default}] - SMB2 Enabled for DC Connections

If this parameter is set to true , the command displays CIFS security configuration information only for CIFS servers where SMB2 is enabled for use with connections to domain controllers. If set to false , the command displays security configuration information for CIFS servers where SMB2 is not enabled for use with connections to domain controllers.
