WARNING

The user ID used to run the command must have permission to modify encryption type and change password for computer object in AD, such as a Domain Admin

  • The SMB server supports the following encryption types for Kerberos communication:
    • AES 256
    • AES 128
    • DES
    • RC4-HMAC
  • To enable AES for an SVM, use the below command:

Cluster1::> vserver cifs security modify -vserver <svm_name> -is-aes-encryption-enabled true

Example:

vserver cifs security modify -vserver VS1 -is-aes-encryption-enabled true

Info: In order to update the advertised encryption types, the password for the CIFS server machine account must be reset. Enter the username and password for the CIFS domain "DOMAIN.LOCAL".

Enter your user ID:

Note: AES should be enabled on the Domain controllers
