We used to use a dynamic LDAP lookup to exchange from our sendmail
boxes, which worked great, until one day we had a problem with the
LDAP on exchange, and the whole thing came crashing to a halt, and
rejected everyone.

So although the dynamic ability of LDAP maps in sendmail is great, we
needed to weigh that up again the loss if it broke again.
Intead I created for a few scripts that runs via cron to extract all
the users from active directory via LDAP, and create a static alias
file whcih are syncronised accross multiple sendmail servers, which
gave us a bit of both dynamic updates, and security from failure.
