I've setup a SSL against LDAP (MS AD) and a HA solution by following the instructions on http://help.sap.com/saphelp_nw04/helpdata/en/cc/cdd93f130f9115e10000000a155106/frameset.htm
and enabled ssl.
What I am wondering if it is possible to setup a HA solution for LDAP which does the following
1. Check on SSL(port 636) against server1.company.com
2. Check on SSL(port 636) against server2.company.com
3. Check on non-SSL(port 389) against server1.company.com
4. Check on non-SSL(port 389) against server2.company.com
(mainly to be a backup in case the certificate is changed or AD is having some problems with SSL)
