RE: Article about OpenLDAP Proxy Server (ITS#3130)
I take it this article has already been published?
If not, I have a few comments:
re: saving your configure command in a shell script, I guess that's a useful
thing to do, but note that there is already a generated config.status file
that shows your configuration options and all the results of such.
I don't see the logical path from "being able to define multiple backends" to
"load balancing." Splitting a database into separate parts does not imply
what is commonly thought of as load balancing. Spreading identical copies of
a database across multiple servers accomplishes that.
Describing the LDAP server as logically consisting of only two parts
(frontend and backend) is misleading, especially when you then go on to
introduce the proxy cache which is definitely neither front nor back. Perhaps
qualifying it as "mainly two parts, with notable extensions in 2.2.x" would
have been better.
re: Installing the server, I'd just like to point out that Symas provides
tested, certified packaged binaries of OpenLDAP for all the major Unix
platforms, Linux, and also Windows. The fact that they're created by someone
who knows how everything is *supposed* to work gives a level of certainty
that no one else can offer: No dependency clashes, no version conflicts, no
miscompiled dependent libraries, It Just Works.
re: the configure options - note that as of OpenLDAP 2.2.9 the configure
option for overlays changed to use the --enable-XXX syntax instead
re: chaining - it seems pointless to say "one reason for partitioning may be
to improve performance" without mentioning how performance may be improved.
To my mind, partitioning always decreases performance; it's only done as a
last resort when a database has grown too big to live in one space. If you're
going to allude to performance improvements, you should provide more support
for such a statement.
Also, listing 6 is unusable without the addition of "subordinate" keywords on
the first two database clauses.
