Actually I wrote them the wrong way, how odd!
I actually have..
group: cache ldap files
passwd: cache ldap files

I think that if it fails ldap, it does so very quickly - it certainly 
did this morning when I rebooted uncleanly.

I believe I did try it as "cache files ldap" but I had some issues, I 
can't recall what they were though. I had quite a bit of difficulty 
getting it to work acceptably so when it did I left it alone :)

On a related note, why is slapd so damn fragile? It's a righteous pain 
in the bum the way you have to run db_recover-X.Y /var/db/openldap-data 
if slapd fails to start.

It wouldn't be so bad if it logged anything, but even with full logging 
it gives a very cryptic message and if you have logging disabled (which 
is recommended for performance!) it won't say _anything_.
