Re: Berkeley DB 4.2.50

FYI

I have successfully upgraded to OpenLDAP 2.1.25 and BDB 4.2.52 (from 
2.1.23 and 4.1.25). It wasn't painless, since I knew next to nothing 
about Berkeley DB.

Afterwards I browsed through the OpenLDAP website, but didn't find 
any upgrade instructions. It might save some bandwidth to add some 
docs, before users start running into problems en masse. Maybe an 
UPGRADE file in the source tarball would do it just as well.

In my experience the upgrade should go like:
1) stop slapd
2) configure, compile and install Berkeley DB 4.2.52
3) configure, compile and install OpenLDAP 2.1.25
4) cd to /your/data/base/dir
5) run db_recover (no arguments needed)
6) start slapd

Steps 4 and 5 took me some time to figure out. The symptoms were that 
slapd wouldn't start and slapcat dumped core, while 'make test' ran 
cleanly. After I got some logging turned on, I got some clues about 
"incompatible environment". It took some more digging before I found 
http://www.sleepycat.com/docs/ref/upgrade/process.html

Now my system is up, running and appears to be stable. I am just 
going to test it some more before I put it into production.
