This feels like an incorrect use of Waitgroup golang/go#8054 (comment) you wg.Wait before all root wg.Add's. .

It seems https://github.com/vjeantet/ldapserver/blob/master/client.go#L88 is getting called after https://github.com/vjeantet/ldapserver/blob/master/client.go#L60 . Any ideas on how to fix this?
