The  problem is that I use it for a general address book and not all people
have email addresses.

Other that that, this still creates a potential problem on local systems
because you may re-use a name like "joe at this.host" when a new joe comes to
town - a very likely event at an ISP.  What I've been doing is creating
CNs of full names and whatever else, like "Joe A Shmoe - jacks friend",
then change the cn to "Joe Shmoe" and use the sn as the full name (for
sorts) "sn: Shmoe Joe A".  I could just as well use a random number
generator for the cn, then change that.  A headache, and I would have
to come up with something better for users.

There should be a way to create a unique number or sequence via php.
I haven't looked into that, but I suspect that's where the real answer
lies.
