Issue

  • Kerberos authentication for NFSv4.1 and/or SMB fails on an Azure NetApp Files Storage Virtual Machine (SVM). Clients are unable to access data, and authentication-related commands fail with Kerberos encryption errors.
  • Common symptoms include:
    • NFS mount operations hanging or failing when using sec=krb5*
    • SMB access failures using Kerberos authentication
    • LDAP or CIFS domain checks reporting authentication errors
    • Failure when enabling Kerberos on an NFS LIF
    • Observed error messages may include:
      KDC has no support for encryption type (KRB5KDC_ERR_ETYPE_NOSUPP)
  • Kerberos-related logs may show that only RC4 or DES encryption types are being negotiated, even though AES is required by Active Directory.
