r14875 (which says "doc improvements"?!) added ldapTemplate in
LDAPSecurityRealm.. next time I saved my top-level Hudson config (which already
used LDAP), my config.xml became 279684 lines long! Nearly all of this is the
<ldapTemplate> item under the LDAP setting. On my next Hudson restart, it fails
when trying to load config.xml.
