I would like to know your opinions and experience while setting-up a centralized authentication server using OpenLDAP.
Currently a have a few hosted servers running a few services (email, webapps, database etc). and a low budged :P
What are the recommended or the best practices when deploying a LDAP server in therms of network security?
What are the hardware requirements on CPU/Memory for a 500-800 user directory? Is it better to have a good hardware single server, or may I go for cheap virtual servers and have a redundant scenario? I know it would be better in therms of HA, but since I am going for a low budget, I also need performance to keep in mind.
If not going for the virtual server option. May the LDAP service run alone on a single server? Or may I share the server with something else... let's say MySQL database? I am just thinking on how make the best use of my resources and not having a too idle server with out adding a security risk on it.
Thank you!
