Currently I have a windows ACS 4.2 version configured with External database authentication "Microsoft Active Directory" and replication from the primary ACS to the Secundary ACS.
The problem we have is that sometimes the PRIMARY ACS lose conectivity whit the Active Directory and doesn´t autenticate clients. At this point the PRIMARY ACS continue responding to the CLIENTS with and unsuccefull authentication, so clients never goint to send the requiretments to the SECONDARY ACS.
There`s any kind of solution like Shutting ACS services when the Active directory doesn`t respond ?
Could be posible configure any kind of Windows database Failover for the ACS ?
ON ACS exist the LDAP database Failover documented .
I hope someone can help me
