LDAPS connection with untrusted Root-CA

Hello together,

we have to change our LDAP-Connection in Serv-U to LDAPS. Normally no problem, but our SSL-Certificate is self-signed or rather said, the Root-CA-Certificate isn't trusted public. Exists a way to:

- ignore this untrusted certificate

or

- import this root-CA-certificate in the Serv-U Trust-Store (the Windows-Trust-Store seems not to be used)?

thanks and best regards,

Markus
