By default, the Kerberos authentication is used in Microsoft Windows 2000 and later.

b: NT LAN Manager (NTLM) is a security protocol proposed in Microsoft Windows NT. This protocol is used to protect user names and passwords during authentication.

c: √ Supported × Not supported or N/A.

  • The OceanStor 18500 V3/18800 V3 storage system can be added into an AD domain, LDAP domain, or NIS domain. However, each domain can have only one such storage system.
  • NFS shares support LDAP/NIS domain authentication but do not support Kerberos authentication.
  • For FTP shares and HTTP shares, the storage system employs User/User Group Management for local authentication.
