Dear All, >You should either use saslauthd or ldapdb, I prefer ldapdb. Your mean is : we can you "saslauthd with ldap support" or ldapdb ? Oh`, I don't know about ldapdb. I will read about it. So I don't need package cyrus-sasl-ldapdb-2.1.22 ? I have juse remove it.It's still alive .hehe. Could you give me some links about using ldapdb? So, it will still use LDAP but another way as ldapdb . I will try now.
