I have read the man page on slapo-unique, and have the following in my 
slapd.conf:

overlay unique
unique_base "dc=myorg,dc=edu"
unique_attributes maillocaladdress,mail

When I try to start the daemon, I get the following error:

line 140 (overlay unique )
overlay "unique" not found

What am I missing?  Do I have to install the overlay from source, or is it 
something built in?
