 Options in this category only apply to the BDB databases. That is,
 they must follow "database bdb" line and come before any subsequent
 "backend" or "database" lines.
+.TP
+.B cachesize <integer>
+Specify the size in entries of the in-memory cache maintained 
+by the BDB backend database instance.  The default is 1000 entries.
+.TP
+.B checkpoint <kbyte> <min>
+Specify the frequency for checkpointing the database transaction log.
+A checkpoint operation flushes the database buffers to disk and writes
+a checkpoint record in the log. The checkpoint will occur if either
+<kbyte> data has been written or <min> minutes have passed since the
+last checkpoint. Both arguments default to zero, in which case they are ignored.
+See the Berkeley DB reference guide for more details.
+.TP
+.B dbnosync
+Specify that on-disk database contents should not be immediately
+synchronized with in memory changes.  Enabling this option may improve
+performance at the expense of data security.
+.TP
+.B directory <directory>
+Specify the directory where the BDB files containing this database and
+associated indexes live.  A separate directory must be specified for
+each database.  The default is
+.BR LOCALSTATEDIR/openldap-data .
+.TP
+.B dirtyread
+Allow reads of modified but not yet committed data. Usually transactions
+are isolated to prevent other operations from accessing uncommitted data.
+This option may improve performance, but may also return inconsistent
+results if the data comes from a transaction that is later aborted. In
+this case, the modified data is discarded and a subsequent search will
+return a different result.
+.TP
+.B
+index {<attrlist>|default} [pres,eq,approx,sub,<special>]
+See the description for LDBM.
+.TP
+.B lockdetect {oldest|youngest|fewest|random|default}
+Specify which transaction to abort when a deadlock is detected. The
+default is the same as
+.BR random .
+.TP
+.B mode <integer>
+Specify the file protection mode that newly created database 
+index files should have.  The default is 0600.
