Vault OpenLDAP Stronger Confidentiality

Hello, I’m trying to setup Vault LDAP Auth and when attempting to authenticate my OpenLDAP server replies with text=stronger confidentiality required. After running some searches, I’ve found the issue to be that Vault does not use a stronger tls_ssf and ssf. Currently it defaults to 128, my server requires 256. Anyone have any ideas as to how to fix this issue that does not require downgrading or switching to StartTLS?
For reference, we are using olcSecurity: simple_bind=256 which is in the slapd.conf(5) man page.
