Comment 17 for bug 81242

@Andreas,

Yes, I am using Postfix + LDAP, but I worked around this problem by running a local slapd that syncrepl's the relevant DB's over SSL, and then configured postfix to use ldap://127.0.0.1. It's far from elegant, but it does have the additional benefit that mail can still be accepted, even in the event the central LDAP server occasionally doesn't answer.

Still, it's sloppy that this has been an issue for about four(!) years now.
