When LDAP Authentication is disabled, User Access will be adjudicated by
either locally-defined user access lists or Avocent management software (see the
section on User Access).
When LDAP Authentication is enabled, locally-defined user access lists take
precedence over requests to LDAP Directory Servers. User access requests with
first check for RCS-defined users. If no match is found, then requests will be
sent to LDAP Directory Servers, as configured.

Access type
LDAP Directory Servers may be setup to operate either in Open or Secure mode
(using SSL - Secure Socket Layer encryption). The mode selected must match
that of the host directory server. When selecting Secure/SSL mode, please also
see the section entitled LDAP SSL Certificates for guidance on meeting the
requirements for encrypted operations.
User caching
Whenever a successful user authentication is completed via LDAP, the RCS has
the ability to retain the results obtained from the LDAP Directory Server for a
selected period of time. If, during that time window, another access request is
generated that normally would result in a repeat request of the Directory Server,
such requests are handled locally on board the RCS. This results in a near
instantaneous response that will allow the user to continue working with
minimal delays.
The three settings for this configuration option are disable, enable, and timeout
period.
