qmail-ldap patch 20040301a & sqwebmail-3.5.3 authldap did not work.

Dear all,
   i have install qmail-1.0.3 & qmail-ldap-20040301a.patch on 
1.qmail-1.0.3
2.qmail-ldap-20040301a.patch
3.openldap-2.0.27-8
4.redhat linux 9.0
  the base system(qmail + ldap support )is fine, i can use smtp ,pop3  and my openldap is work too.

now i install sqwebmail-3.5.3 with ldap auth.

my install :
1.  ./configure 
2. make configure-check
3. make
4. make check
5. make install-strip       
6.make install-configure 
it seems every is ok.  

i can access the login page at http://localhost/cgi-bin/sqwebmail
and "/usr/local/share/sqwebmail/libexec/authlib/authdaemond start" is in my /etc/rc.d/rc.local file.


but i can not login success, it's seem the authldap module did not work .
my authdaemonrc file is :
###########################
authmodulelist="authldap"
authmodulelistorig="authcustom authcram authuserdb authvchkpw authldap authpam"
daemons=5
version=""
authdaemonvar=/usr/local/share/sqwebmail/var/authdaemon
############################################################################
i bypass the comment line.

my authmodulelist file is:
#############
authdaemon
#################################
my authldaprc is correct.
i use  ldapsearch can find every ojbect in my qmail-ldap ldbm directory.

i can not resolve the problem , can sqwebmail print some debug information  to a log file ?
i replace /usr/local/share/sqwebmail/ldapsearch with 
######################
echo "$@" >> /tmp/sqwebmail.log
exec /usr/bin/ldapsearch -l 60 -z 20 "$@"
############################################
but i can not find the /tmp/sqwebmail.log file after several login via sqwebmail.

my openldap library is in /usr/lib .
what's the problem????????????????
i need help 
thanks

best regards!
