```java
public enum WitnessServiceType {
    CLUSTER_WITNESS,     // Cluster-aware witness service

		// If separator is not found or is last entry, ok.
		return idx == -1 || idx == len(ext)-len(separator)
	}
	return false
}

// isLatestDeletemarker returns whether the latest version is a delete marker.
// If metadata is NOT versioned false will always be returned.
// If v2 and UNABLE to load metadata true will be returned.
func (e *metaCacheEntry) isLatestDeletemarker() bool {
	if e.cached != nil {

}

		deleteKeyEtcd(ctx, ies.client, getMappedPolicyPath(user, userType, false))
		return nil
	}
	if u.Credentials.AccessKey == "" {

	// Objects matching prefixes should not leave delete markers,
	// dramatically reduces namespace pollution while keeping the
	// benefits of replication, make sure to apply version suspension
	// only at bucket level instead.
	opts.VersionSuspended = globalBucketVersioningSys.Suspended(bucket)
	// For directory objects, delete `null` version permanently.
	if isDirObject(object) && opts.VersionID == "" {

	if newGlobalAuthZPluginFn() != nil {
		return claims, nil
	}

	// Check if a session policy is set. If so, decode it here.
	sp, spok := claims.Lookup(policy.SessionPolicyName)
	if spok {
		// Looks like subpolicy is set and is a string, if set then its
		// base64 encoded, decode it. Decoding fails reject such
		// requests.

            // TODO use kryo.register for security

            // which could potentially lead to remote code execution vulnerabilities.
            // This should be replaced with explicit class registration using kryo.register()
            // for all classes that need to be serialized/deserialized.
