[Dovecot] EXIM + Dovecot - Auth mechanism

[Proskurin Kirill]

Hello all.

Sorry for a lot of question - im making a new mail system now.

Im wondering how to auth different MUA.
For example Thunderbird & The Bat 4.x - CRAM-MD5
MS Outlook 2007  - DIGEST-MD5

Im create a 3 users and store passwords in LDAP using MD5-CRYPT(1), 
CRYPT(2) and MD5(3) - for tests.

If im not use "secure connection" in thunderbird - im auth fine(plain 
text over SSL) but then im try to SMTP Auth by 1 and 2 user im got a error:

"Requested CRAM-MD5 scheme, but we have only CRYPT"

And after any auth in logs im have this:
dovecot: Jul 03 13:31:47 Error: auth(default): BUG: Authentication 
client gave a PID 70487 of existing connection

Then im try to auth by 3 user im got:
"Requested CRAM-MD5 scheme, but we have only PLAIN-MD5"

If thunderbird
Then im try to Auth in Outlook im got a error too:

auth(default): digest-md5(?,172.16.1.226): Invalid realm: domain.off


What should im do to auth successful in this scheme?

exim config:

begin authenticators

auth_plain:
driver = dovecot
public_name = PLAIN
server_socket = /var/run/dovecot/auth-client
server_set_id = $auth1

auth_login:
driver = dovecot
public_name = LOGIN
server_socket = /var/run/dovecot/auth-client
server_set_id = $auth1

auth_cram_md5:
driver = dovecot
public_name = CRAM-MD5
server_socket = /var/run/dovecot/auth-client
server_set_id = $auth1
