Re: GDBM vs BDB as openldap backend.

[Justin Zygmont <jzygmont@solarflow.dyndns.org>]

is there anywhere that explains what the differences are with these 
database types, etc?  I went through the administrators guide and it's 
almost useless.  I'm trying to setup a RH 8 system to have all systems use 
it for authentication.  When I changed the database type to passwd and did 
a search, things started looking like it could work, but I still can't 
authenticate to it.  I'm new to directories, is there anything i'm 
missing?

any help would be appreciated
