LDAP Server Failover
I followed the steps noted in LDAP Red paper and E-LDAP: Can LDAP be Setup for Failover or Load Balancing? (Doc ID 611763.1).
I found an issue when testing.
I setup PeopleSoft LDAP as suggested - 1 Authentication Map and 1 User Profile Map for every server 1:1
Adding additional maps reveled issues where user entered incorrect AD user id and password.
AD password controls allow 5 attempts in our env.
What happens is PeopleSoft fails to authenticate on map 1 and tries map 2, 3, 4 and 5. For each map (server) AD ‘badPwdCount’ gets incremented. In this case where 5 maps were setup the account was locked.
It appears Failover can't be implemented.
