HP Onboard Administrator - Manual (Page 330)

Enabling LDAP Directory Services Authentication to Microsoft Active Directory 330
Verify that the Onboard Administrator has all the appropriate network settings unique to your network (such
as DNS) and that the time and date are correct (certificates are date sensitive). Ensure that Onboard
Administrator can reach the DNS server (by pinging it from the Onboard Administrator command line
interface).
If LDAP is enabled while booting into Lost Password mode, the local Administrator password is reset, LDAP
is disabled, and local login is re-enabled.
NOTE: The Onboard Administrator LDAP feature supports Microsoft® Active Directory using the
memberOf attribute. Novell eDirectory is also supported with the groupMembership attribute.
OpenLDAP is not supported.
