If a customer has a self-signed certificate installed on their AD server, what type of encryption would the Directory Sync connector need?

When using a self-signed certificate for a Directory Sync connector, the appropriate type of encryption needed is classified as relaxed encryption. This approach is applied because the self-signed certificate is not issued by a trusted Certificate Authority (CA), which typically enforces stricter requirements for establishing secure connections. Relaxed encryption allows for flexibility in validating the certificate, acknowledging that the self-signed certificate may not provide the same level of assurance as a certificate from a recognized CA.

In practical terms, relaxed encryption accommodates scenarios where security practices may not be as stringent, thus enabling the synchronization process to proceed without strict validation protocols that could disrupt connectivity due to certificate trust issues. This facilitates a smooth operation in environments where self-signed certificates are common, without compromising the essential security features of the sync operation when appropriately used.
