We use the MIT Kerberos for both it and AFS.  As you can see we have
just over 20,000 principals:

root@kerberos-1> wc -lwc dbase                       <--- text dump of DB
   20020  240240 1484174 dbase

Of course, the dbm file *looks* much bigger:

-rw-------  1 root         32768 Jan 12 17:29 principal.dir
-rw-------  1 root     242170880 Jan 17 19:05 principal.pag

but, it's actual size about 1/10 of that:

root@kerberos-1> du -s principal.pag
20928   principal.pag

(It does look like dbm might crap out around 200,000 principals)
