Unexpected LDAP error - ssoadm

The project I am currently on requires High Availability for Single Sign-On in the production environment. A site is configured for this purpose having 2 nodes.

Today, I was debugging something and shut down Node 2 and used ssoadm.jsp to update a service (update-svc) which I previously created.

When I tried to save, I get Unexpected LDAP error on the UI.

I found out why when I saw the following in Configuration log file:

ERROR: SMSLdapObject.modify(): Error in modifying entry: ou=1.0,ou=sunAMAuthXXXAuthService,ou=services,o=XXX,c=sg
By Principal: id=amadmin,ou=user,o=XXX,c=sg
com.sun.identity.shared.ldap.LDAPException: error result (53); The Replication is configured for suffix  o=Ministry of Education,c=SG but was not able to connect to any Replication Server

        at com.sun.identity.sm.ldap.SMSLdapObject.modify(SMSLdapObject.java:435)

Hmm... any configuration change requires both nodes in the site to be up! Is this built by design? I need to find out more ...
