How to set ONTAP to use LDAP Signing or Sealing for CIFS/NFS

Last Updated:

Applies to

  • ONTAP 9 
    • Common Internet File System (CIFS)
    • Network File System (NFS)
    • Lightweight Directory Access Protocol (LDAP)


  • Beginning in ONTAP 9, you can configure signing and sealing to enable LDAP session security on queries to an Active Directory (AD) server.
    • You must configure the CIFS server security settings on the storage virtual machine (SVM) to correspond to those on the LDAP server.
    • Signing confirms the integrity of the LDAP payload data using secret key technology.
    • Sealing encrypts the LDAP payload data to avoid transmitting sensitive information in clear text.
  • An LDAP Security Level option indicates whether the LDAP traffic needs to be signed, signed and sealed, or neither. The default is none.
  • Setting these options are expected to be non-disruptive operations. Existing cifs\nfs connections will not be impacted by this change: More information
