I run into problems using either the console or just ldif file (which I prefer, for scripting).  Here's the typical problem: when I try to set nsAdminAccessHosts, I use an ldif file.  I can see the new value is set in the operational attributes, but it doesn't always make it into /opt/fedora-ds/admin-server/config/local.conf.  The admin server logs indicate it is using the old values.

If you modify settings yourself in the configuration DS via LDAP, you 
will have to tell Admin Server to refresh its configuration.  The 
console does this when you change admin server parameters.  It uses the 
special url path "/Commands/sync-task-sie-data".  You must authenticate 
to http first becauses it uses those credentials to bind to the 
directory server to read the new configuration.  This is how local.conf 
is updated with the information from the config ds.

http://directory.fedoraproject.org/wiki/AdminServer#Admin_Server_Config_Files 
gives an overview of the various Admin Server config files.  One thing 
it doesn't say is what the ownership should be.

admin-serv/config - directory - should be owned by the admin server uid 
and should be mode 0700.
adm.conf - must be owned by the admin server uid (default nobody) and 
mode 0600
admpw - must be owned by the admin server uid (default nobody) and mode 0600
local.conf - must be owned by the admin server uid (default nobody) and 
mode 0600
console.conf - must be owned by the admin server uid (default nobody) 
and mode 0600

All other files can be owned by root and be read only.

So, I tried, for a test, setting the owner:group to ldap:root.  When I did this and restarted admin server, I got this error:

Richard suggested looking in the logs to see what was happening, but I found no clues there.  If anyone has one...
