Applies to

  • ONTAP 9
  • Data ONTAP 8
  • AV Connector
  • Domain Tunnel

Issue

A Domain user is defined on the AV Connector and NTLMv2 Authentication is disallowed.

2 Known Causes:

  • vserver 'lm-compatibility-level' parameter is set to support 'krb' only
  • Active Directory GPO disallows NTLM

 

This impacts anything that wants to use domain-tunnel for CIFS authentication
