I sent these patches to krb5-bugs, but got no ack from anything/anyone.
Rather than have everybody re-invent the wheel, here's some more
patches for BSD/OS v2.0.
You will need to configure with --ccp-opts=-DDB_DBM to get
this to work.
I've #ifdef'd the code around DB_DBM.
These patches are necesary for anybody who wants to run the
kerberos server on a machine that uses the "libdb" routines,
rather than a traditional "ndbm" or "dbm" database. This
certainly includes BSDi v1.1 and v2.0, as well as the
NetBSD and FreeBSD efforts. I have no reason to suspect that
these changes will not work on all these platforms.
Hope this helps the V5 effort a little bit.
