Lots of programs use CDB. Off the top of my head:

Radiator, a commercial RADIUS server written in Perl can use it.
TMDA (Tagged Message Delivery Agent), an open source challenge response 
system, written
in Python uses it.
There are patches for sendmail to use tinycdb.
I believe there are patches for postfix also.

Basically, it's great for use in email applications.

And it's fairly standard. You can view the spec here:

There is also tinycdb, a free implementation of DJB's CDB database:
