How to enable spamassassin with user preference in LDAP when running with Mailscanner ?

[Anny Lei]

Dear developers,

I am using Mailscanner with Spamassassin and I want Spamassassin lookup LDAP 
for user preference.  I have put user_scores_dsn, user_scores_ldap_username, 
and user_scores_ldap_password in local.cf.  When I test running the command 
'spamd -D --ldap-config -x', then  cat /root/sample-spam.txt | spamc -u 
[EMAIL PROTECTED]', it works perfectly fine.   But when Mailscanner 
accepts the email, Spamassassin doesn't lookup ldap for user preference (as 
observed from ldap.log file).   I do not know where to 
specify --ldap-config -x command for Spamassassin because  Mailscanner is 
not calling Spamassassin daemon, spamd.

Could you please let me know how to instruct Spamassassin to lookup LDAP for 
user preference when running with MailScanner ?   Thanks in advance for your 
assistance.

Regards,
Anny
