Unsuccessful Previous Authentication with the Primary LDAP Server
If, on the previous LDAP authentication attempt, Cisco Secure ACS could not
connect to the primary LDAP server, whether Cisco Secure ACS first attempts to
connect to the primary server or secondary LDAP server for the current
authentication attempt depends on the value in the Failback Retry Delay box. If
the Failback Retry Delay box is set to 0 (zero), Cisco Secure ACS always attempts
to connect to the primary LDAP server first. And if Cisco Secure ACS cannot
connect to the primary LDAP server, Cisco Secure ACS then attempts to connect
to the secondary LDAP server.

If the Failback Retry Delay box is set to a number other than zero, Cisco Secure
ACS determines how many minutes have passed since the last authentication
attempt using the primary LDAP server occurred. If more minutes have passed
than the value specified in the Failback Retry Delay box, Cisco Secure ACS
attempts to connect to the primary LDAP server first. And if Cisco Secure ACS
cannot connect to the primary LDAP server, Cisco Secure ACS then attempts to
connect to the secondary LDAP server.
