We have an internal application (Server-A) that has a hardcoded IP for LDAP lookups. The LDAP server is also internal, but on a different interface/VLAN of the ASA. The LDAP server (LDAP-A) is experiencing problems, and I would like to temporarily redirect LDAP (tcp/389) lookups from Server-A to LDAP-B. We can't change the destination IP in Server-A's configuration. LDAP-A and LDAP-B are on the same subnet.
Normal traffic flow looks like this:
Server-A -> ASA int 1 -> ASA int 2 -> LDAP-A
I somehow need ASA int 1 to see LDAP-A's destination address and rewrite it to LDAP-B's IP. Is this possible?
