That's exactly what the mail_home is. I don't know why it wouldn't work

Assuming you're not using auth_bind=yes with ldap, LDA can check the
user's existence by doing a passdb lookup instead.

Can you get a gdb backtrace? First enable core dumps with "ulimit -c
unlimited" and once you have core file see

this should be:

iterate_attrs = samaccountname=user
