How to configure LDAPS in FlexNet Operation(Onprem) where the FNO is already using LDAP communication with Active Directory?

Answer

LDAP is used to read from and write to Active Directory. By default, LDAP traffic is transmitted unsecured. You can make LDAP traffic confidential and secure by using SSL technology.

From the Active Directory server-side you can enable LDAP over SSL (LDAPS) by installing a properly formatted certificate from either a Microsoft certification authority (CA) or a non-Microsoft CA according to the guidelines in this article.

4. Protocol from LDAP to LDAPS then the port will automatically change from 389 to 636 
5. Save the config.
