Vendor Workaround
Option 1 (Recommended): Disable the SSO token feature entirely: dsconf <instance> config replace nsslapd-enable-ldapssotoken=off. This prevents the vulnerable code path from being reached but disables SSO token functionality for all users. Option 2: Restrict network access to LDAP ports (389/636) to trusted networks via firewall rules. Note: Removing the SSO token secret from configuration does not mitigate the vulnerability — the server auto-generates a new secret at startup.
