The mailing list for listmasters using Sympa

[address@concealed]

I've been trying to Ldap authenticate an installation of Sympa.  

My auth.conf file currrently looks like

ldap
regexp                          .*
host                            ldap.myco.com:389
timeout                         30
suffix                          cn=manager,dc=myco,dc=com
get_dn_by_uid_filter            (uid=[sender])
get_dn_by_email_filter          (mail=[sender])
email_attribute                 mail
scope                           sub

#user_table
#regexp .*

I then restart sympa /etc/init.d/sympa stop then /etc/init.d/sympa/start, then
i try to log into my wwsympa login page using my Ldap uid and password - and
I'm unable to log in using my Ldap credentials.

snippets of my sympa.log during the failed login:

Mar  6 16:09:30 hostname wwsympa[32544]: No entry in the Ldap Directory Tree 
of
ldap.myco.com:389 for myuid
Mar  6 16:09:30 hostname wwsympa[32544]: Incorrect Ldap password
Mar  6 16:09:30 hostname wwsympa[32544]: Authentication failed
Mar  6 16:09:30 hostname wwsympa[32544]: [robot hostname] [client 123.1.1.12]
do_loginrequest

Is there anything glaringly obvious that I'm doing wrong or anything that I'm
skipping in order to get Ldap authentication to work?
