In the 2.4.33 release of OpenLDAP, it was possibly to resize an MDB database by
modifying olcDbMaxsize while slapd was running.  This functionality no longer
works in current RE24.  This is highly desirable behavior, as one may wish to
reduce the maximum DB size after determining how large the actual MDB is.  With
current RE24, changing olcDbMaxsize to a smaller value leaves the data.mdb file
the same size as it was before.

2.4.33 behavior:

80GB initial maxsize: zimbra@zre-ldap002:~$ ls -l data/ldap/mdb/db
total 692
-rw------- 1 zimbra zimbra 85899345920 Dec 11 10:46 data.mdb

After modifying cn=config with a 10MB maxsize:

zimbra@zre-ldap002:~$ ls -l data/ldap/mdb/db
total 692
-rw------- 1 zimbra zimbra 10485760 Dec 11 10:51 data.mdb
