Well, would have been nice, though. I'll stick to rsync to distribute
secret keyrings then.

I was unaware that _all_ keyserver options apply to any type, i.e.
The manpage talks about 'a' preferred keyserver, though, so I thought
that there can be only one, which means all options are global anyways.
Haven't had a look at the new auto-key-locate feature yet.

No, not yet but would make sense now with binddn and binddn.
However, just a single LDAP server I can authenticate against, is fine for me.

That's what I meant with "general limitation" above.

If you create a framework which allows for options to apply to
certain keyservers, why limit yourself to LDAP only?
What if HTTP or FTP keyservers require authentication?
How would you do e.g. basic authentication against multiple
HTTP keyservers, each with different username and password?
Therefore, implementing keyserver specific options _just_ for LDAP
simply doesn't make sense, or does it?
