Hello ,
        I tried to use authentification with sympa to a nestape directory 
server 
version 4.  
sympa is working with ldap list type. 

I can see this error in sympa log:

I can't see any ldap connections with tcpdump between 
ldapserver and sympa server.

my auth.conf is read by sympa ldap
        host                            svrs2.ac-montpellier.fr:389
        timeout                         30
        suffix                          o=gouv,c=fr
        get_dn_by_uid_filter            (|(uid=[sender])(ou="personnels 
EN")(ou=ac-montpellier)(ou=education))
        get_dn_by_email_filter          
(|(mail=[sender])(mailalternateaddress=[sender]))
        email_attribute                 mail
        alternative_email_attribute     
mailalternateaddress,mailforwardingaddress
        scope                           sub

Any help will be appreciate.

Thanks
