1) Nothing about ldap specifices the _directory_ (_not_ database) is
kept in memory. Ldap is an access protocol, not a storage
implementation.

2) It was not specifically made for distributed server systems, it
was designed for ease of client iplementation and simplicity of
access and searching.

Also, there is at least one free (as in beer) implementation, see

  http://www.openldap.org

Big ldap databases are usually an ldap adapter to an enterprise
rdbms like Oracle or Informix. Also, ldap is optimized for reads,
not writes.  There is a big difference between a directory and a
database, with some important tradeoffs. Personally, I don't see how
ldap would help a mud much.
