If I recall correctly, in our environment, if the server needing ldap access did not need to write to the directory, e.g., password updates, we did not enter the directory manager password at all. On those systems that do, I thought it was stored in a separate file - something like ldap.secrets - and that file we could set as 600. Beyond that, we also disable anonymous access, create various read only browsing users (for different parts of our multi-client tree) with minimal access and use those as the binddn and bindpw users in ldap.conf. I hope this is what you are looking for. Good luck - John -- John A.
