As I understand it, LDAP and MySQL offer two different ways of setting up a networked address book. So I take it they can be compared as far as that is concerned. Actually, I normally run Linux, so Active Directory would not be a priority for me. I didn't say LDAP was a database. However, the principal usage of LDAP, as far as I can see (by googling for LDAP) is in fact to set up a network address book of some kind. It may be used for other purposes, but they are not really relevant to my enquiry. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
