I used a guide "Postfix Virtual Hosting With LDAP Backend And With Dovecot As IMAP/POP3 Server On Ubuntu Kamic Koala 9.10" in my debian lenny, but I have a problem with LDAP. In the first page when add, with root user, a new schema obtain: server:~# ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/ldap/schema/cosine.ldif SASL/EXTERNAL authentication started SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth SASL SSF: 0 adding new entry "cn=cosine,cn=schema,cn=config" ldap_add: Insufficient access (50) and same with other schema Is there a reason? plaese
if you just want to set up a mail server that support ldap. you can try iRedMail if support debian. Ubuntu.
