[Dovecot] Dovecot CRAM-MD5 & DIGEST-MD5

[Proskurin Kirill]

Hello all.

Im try to make a SMTP Auth using Docecot SASL.
Im use swaks for tests.

Im store users in LDAP.
As im understand for CRAM & DIGEST MD5 we need to store pass in a clear 
text?... Ok.

mail: admin3 at domain.off
userPassword: 123 <- Clear text


What im do


%swaks -a CRAM-MD5 -au admin3 at domain.off -ap 123
To: admin3 at domain.off
=== Trying mx.domain.off:25...
=== Connected to mx.domain.off.
<-  220 mx.domain.off ESMTP Exim 4.69 Tue, 08 Jul 2008 19:14:24 +0000
  -> EHLO mx.domain.off
<-  250-mx.domain.off Hello mx.domain.off [172.16.1.19]
<-  250-SIZE 13631488
<-  250-PIPELINING
<-  250-AUTH PLAIN LOGIN CRAM-MD5 DIGEST-MD5
<-  250-STARTTLS

*** No authentication type succeeded
  -> QUIT

Hm... as im see - something wrong in my dovecot-ldap.conf ?
Main idea of it is mail = user, userPassword = password.


dovecot-ldap.conf:

hosts = 127.0.0.1
dn = uid=Dovecot,ou=System-Users,dc=DOMAIN
dnpass = 123
debug_level = 0
ldap_version = 3
base = dc=Virtual-Domains,dc=DOMAIN
deref = never
scope = subtree
user_attrs =
user_filter = (&(objectClass=mailUser)(mail=%u))
pass_attrs = mail=user,userPassword=password
pass_filter = (&(objectClass=mailUser)(mail=%u))
default_pass_scheme = CRAM-MD5


Dovecot logs with debug_level=1 in attachment.


Help me please - I running out of ideas. :-(
