[Exim] LDAP lookups

Morning.

Has someone succeeded in making Exim verify local-parts in LDAP? At
least looking up `uid's is what is highly desired.

Of course I could stay with pam_ldap (I don't have virtual
user-domains) but sometimes Exim fails accessing it.
Still `getent passwd' is OK. Restarting exim doesn't help. Restarting
`nscd' do. BTW if I remove nscd or switch down passwd-caching in
nscd.conf I get the same -- exim fails to find local-part...

Thanks in advance.
