Folks: I'm sure there are some of you that are saying, "The newsletter is late, where is it?" The answer is, it is coming along. Working on the LDAP server Performance has been a great deal of fun and a good challenge. There is so much material, that it takes times to sift through it. The first issue in the series is a DOUBLE issue on Benchmarks and Load Testing. Future issues will delve more into these areas as well as discuss Server Sizing, Server Certification and much more. The goal is be done by the end of the month..give or take. Thank you for your patience.
