[otrs] LDAP Bind

Hi, We're using OTRS 2.2.7 and trying to set it up for LDAP customer authentication. Turns out the campus server doesn't allow anonymous binds and I won't be able to create a login just for OTRS authentications because of their policy. Is there a way to configure the Config.pm to use values from the login form for: $Self->{'Customer::AuthModule::LDAP::SearchUserDN3'} = ''; $Self->{'Customer::AuthModule::LDAP::SearchUserPw3'} = ''; or any other way to get the username/password values from the login form to create the bind credentials? Thanks! Terrill
