Hello list! I'm now getting closer to LDAP-based authentication. What I now get is that when I try to login as a Customer, I get "Panic! no User Data!!!" error. The log shows that the authentification is ok. Where may the error be? $Self->{'Customer::AuthModule'} = 'Kernel::System::CustomerAuth::LDAP'; $Self->{'Customer::AuthModule::LDAP::Host'} = 'srv-vco-1.provincia.verbania.it'; $Self->{'Customer::AuthModule::LDAP::BaseDN'} = 'dc=provincia,dc=verbania,dc=it'; $Self->{'Customer::AuthModule::LDAP::UID'} = 'sAMAccountName'; $Self->{'Customer::AuthModule::LDAP::SearchUserDN'} = 'CN=ldapuser,OU=Utenti-test,DC=provincia,DC=verbania,DC=it'; $Self->{'Customer::AuthModule::LDAP::SearchUserPw'} = 'ldap'; Meny thanks -- ---------------------------------- Boniforti Flavio Provincia del Verbano-Cusio-Ossola Ufficio Informatica Tecnoparco del Lago Maggiore Via dell'Industria, 25 28924 Verbania ----------------------------------
