Maybe I just don't understand how this log removal is suppose to
function.  I'm confused by the comments above since all the db tools
seem to find the logs fine.  Giving the -h option seems to have no
effect. It seems that since the "set_lg_dir /var/lib/ldap/bdblogs" is in
DB_CONFIG the slapd_db_archive command fines the logs just fine.  

For a test I moved all the logs (135) up one directory to the location
of the db and the DB_CONFIG file, stopped slapd, recovered the db,
restarted slapd.  At this point 135 log.xxx files are in the directory, 
I ran slapd_db_archive and it shows 134 of the files are not being used.
 I would have thought that with the  set_flags DB_LOG_AUTOREMOVE set in
DB_CONFIG it would remove the log.xxx files that slapd_db_archive says
is not needed.  Is this how it works? Or do they eventually get removed
based on some other criteria?
