Applies to

  • ONTAP 9
  • CIFS/SMB Protocol
  • Advanced Encryption Standard (AES) encryption

Issue

  • Enabling CIFS AES encryption on one SVM requests AD domain credentials:
cluster01::> vserver cifs security modify -vserver svm_cifs01 -is-aes-encryption-enabled true
Info: In order to enable CIFS AES encryption, the password for the CIFS
server machine account must be reset. Enter the username and password
for the CIFS domain "EXAMPLE.COM".
Enter your user ID: domain_admin
Enter your password:
Error: command failed: Password update failed. Reason: SecD Error:
machine account does not exist.
  • The same setting can be modified on other SVMs without requesting domain credentials.
  • AutoSupport data shows all discovered domain controllers as unavailable for the affected SVM.

Example:

node01 svm_cifs01 example.com MS-DC dc01 adequate 192.0.2.10 unavailable UNKNOWN false
node01 svm_cifs01 example.com MS-DC dc02 adequate 192.0.2.11 unavailable UNKNOWN false
