You probably wouldn't run it through Apache, but you probably COULD run an LDAP server of sorts using http://php.net/sockets Main problem is one of performance. The reason most people choose LDAP in the first place is to get blazing fast performance, because they NEED it. PHP is probably not going to give you blazing fast performance compared to an off-the-shelf LDAP server in C. You may be able to leverage from the code in http://php.net/ldap to move most of the heavy lifting into an extension, or perhaps you could expand that extension to do so, and then you just have a simple PHP wrapper to handle the sockets part. That would help some, and possibly even come "close" to C performance, since the socket open/close/traffic/bandwidth is probably the limiting factor there, rather than a single PHP byte-code interpreted function call... This is all just my expectations. Feel free to surprise me with actual test results. :-) ymmv -- Some people have a "gift" link here. Know what I want?
