LDAPS relying on AD certificates from private CA: Certificates used in the UA Domain are issued from a private local CA.  Shibboleth configurations will fail to load if they cannot establish trust.  Trust of the private CA can be established by:
(1) Import the certificate into the java trusted keystore.  This requires ongoing maintenance as that keystore may be overwritten by any number of upgrade or refresh processes, requiring re-import of the CA certificate.
(2) Configure the IdP authentication module to trust the AD certificate by adding to the configuration in $IDP_HOME/login.config a line like

{{{
sslSocketFactory="{trustCertificates=file:/path/to/my/trust.crt}"

=== [[IdPSetup|Failover connectors]] ===

If a !DataConnector fails in attribute resolution - for example, if the connection to the server fails because the server is off-line, attribute resolution is aborted, even if attributes were successfully retrieved using other !DataConnectors.  To minimize the impact of such connection failures, include failover in the !DataConnector definition.  Connections that fail because of a certificate trust failure apparently always abort; certificate trust failure is in effect a fatal error for the IdP.
