[K12OSN] What's the difference between OpenLDAP backen dbm and ldbm

[Brian Webport]

We're happily running our Samba 3 / OpenLDAP system setup using the 
smbldap-installer script. I've been looking around trying to do a little 
background reading on the OpenLDAP section and I'm a little confused as 
to what the difference is between dbm & ldbm for the backend database.

I see from our slapd.conf file that the installer uses ldbm is this 
better then dbm ??

Any information would be greatfully received.

Thanks
