There are a few projects in bioinformatics which make sequence
records available via LDAP

There's at least one posted idea for doing that at
   http://mla.libertine.org/tmda-workers/2001-11/msg00110.html
but it's only in the "wouldn't it be interesting if" stage.

But I know rather little about LDAP's uses.  Being googlesmart,
I did find
   http://www.networkmagazine.com/article/DCM20000502S0039
which describes where LDAP is/is not appropriate.  It says
 > LDAP isn't a replacement for relational databases (and never

and elsewhere that it's not good for BLOBs, so while you said
it's not good for replacing a DB, DNS, etc., well, that's
already well-known, and not what it claims to be good for,
which is managing information about resources.

For me, I have about as much need for LDAP (right now) as I
do for ICQ; none.  Maybe next year for LDAP, when looking into
some of those sequence databases.
