Applies to

  • ONTAP 9
  • Active Directory (AD) LDAP
  • NFS
  • CIFS

Issue

  • NFS user cannot access volume, because ONTAP cannot resolve Unix account.
  • CIFS user cannot access share, because ONTAP cannot name map Windows account to Unix account.
  • Packet trace shows that:
    • ONTAP sends search filter (&(objectClass=User)(uid=unix_username)) to LDAP server
    • LDAP replies that no matching search results were found
