[midPoint] Using Active Directory with Virtual IP for Failover

[Jason Everling]

Yeah so I am using the serverless binding with the connector server
installed on each DC and if I am getting what you mean correct, I was
imagining it would look something like this:

Virtual IP going through Citrix Netscaler: 10.10.20.10 which in DNS is
LDAP.TEST.LOCAL

DC1 - Connector Server Installed using local IP <add
key="connectorserver.ifaddress" value="10.20.10.5" />
DC2- Connector Server Installed using local IP <add
key="connectorserver.ifaddress" value="10.50.10.5" />


midPoint Connector Host would use the virtual DNS ldap.test.local

<connectorHost xmlns="
http://midpoint.evolveum.com/xml/ns/public/common/common-3">
    <name>Active Directory</name>
    <hostname>LDAP.TEST.LOCAL</hostname>
    <port>8759</port>
    <sharedSecret>SECRET</sharedSecret>
</connectorHost>

AD Resource would use the virtual DNS ldap.test.local

                <icfcad:LDAPHostName>ldap.test.local</icfcad:LDAPHostName>
                <icfcad:SearchChildDomains>false</icfcad:SearchChildDomains>
                <icfcad:DomainName>test.local</icfcad:DomainName>

<icfcad:SyncGlobalCatalogServer>ldap.test.local</icfcad:SyncGlobalCatalogServer>

<icfcad:SyncDomainController>ldap.test.local</icfcad:SyncDomainController>

Citrix Netscaler IP would be setup using Primary/Secondary and NOT load
balanced.
