Applies to

  • ONTAP 9
  • CIFS/SMB
  • Kerberos
  • Active Directory

Issue

  • Used Active Directory Attribute Editor to change CIFS server's machine account's attribute msDS-SupportedEncryptionTypes to value 30
  • Afterwards, CIFS clients that navigate to \\hostname cannot access data because Kerberos authentication fails
  • CIFS clients that navigate to \\1.2.3.4 can access data because NTLM authentication succeeds
