EEM 12.6 is basically a combination of two pieces
- iGateway using port 5250
- CA Directory using port 509
In case the client would like to have TLS v 1.2 with external LDAP also, they need to upgrade EEM server to R12.6.
With EEM 12.6, the communication layer has been changed to Open LDAP which fully supports TLSv1.2.
On EEM server, in igateway.conf file under location $IGW_LOC (unix) or %IGW_LOC% (windows):
In <Connector name="defaultport"> tag, set the protocol to TLSV1.2
