Postfix: Rewriting sender email address from ldap lookups


Hi,


I'm trying to setup postfix to rewrite a sender address from
userid@hostname.domain.com to firstname.lastname@domain.com

Basically just rewriting entire address to the userid's email address from ldap.

Can anyone give me some tips on how I might do this?

Thanks!

This is what I've got so far:

In main.cf:
canonical_maps = ldap:/etc/postfix/ldap-canonical.cf


In ldap-canonical.cf:
server_host = ldap.domain.com
search_base = ...

bind = yes
bind_dn = ...
bind_pw = ...


query_filter = sAMAccountName=%u
result_attribute = mail

I take the above two lines to mean:
find the ldap entry that has sAMAccountName = to the local part of the sender address (eg: userid from userid@pcname).
Use the "mail" entry as the result address. Am I wrong here?

I think it's authenticating just fine but I'm getting the following error in my log file:
warning: dict_ldap_lookup: Search error 9: Partial results and referral received
Apr 18 09:22:15 pcname postfix/cleanup[32577]: warning: 10C2A7BC464: canonical_maps map lookup problem for userid@pcname

This should be a pretty simple task ... any postfix admins have any thoughts?

Can you show us a relevant ldap entry?

I got it working with a little googling ...

My LDAP server is Active Directory running on MS Server 2003.
I added:

version = 3

to my ldap-canonical.cf file and everything started working.
I guess postfix defaults to version 2 and AD on MS Server 2003 uses version 3.

Hopefully this helps someone else out there.
