JSA is unable to connect to TLSv1.2 LDAP servers over SSL connections even though the test connection succeeds.
Authentication is failing.
Perform the following workaround to accomplish the same goal, but uses a different way to secure the connection, using ldap/389 and TLS directives for the security:
In the LDAP repository, change the Server URL from "ldaps:// <server> :636" to "ldap:// <server> :389"
Set the TLS Authentication checkbox from 'false' to 'true'.
