I'm evaluating upgrading our LDAP services and moving from hdb to mdb.

I don't seem to be able to get my MDB database to resize by changing the value of maxsize, whether increasing it or decreasing it.

I'm using slapd.conf, so changes to the config require a restart. Looking at debug output when slapd starts I can see that the new value of maxsize is being read.

If I delete the database and rebuild with slapadd then it's created with the new size.

I see there was an ITS#7471 reporting a similar issue, but this was apparently fixed in 2.4.34 (if that's what RE24 is) - I'm using 2.4.35.

In my config maxsize is the only MDB setting I've used, everything else will be using default values.

Should it be possible to resize MDB this way? I haven't been able to track down much information about resizing beyond the issue report mentioned above.

In practice I expect it's something that I'll rarely (if ever) have to do, but I'd like to at least understand what I should be able to do.
