[Dovecot] Master user and proxying

[BaQs]

Hello list, 

Still need your help configuring proxy infrastructure.


Today, I really struggle configuring master passwords forwarding. 

What
I want: 

master user can connect to any other account, on proxy. 

Could
please somebody help me, I read both articles about this on wiki, but still
can't connect :( 

What I did: 

on proxy: 

auth_master_user_separator=*

passdb sql {
 args = /usr/local/dovecot/etc/dovecot-master.conf
 master =
yes
 pass = yes
 } 

-- 

dovecot-master.conf:
(...) 

default_pass_scheme
= CRYPT

password_query = SELECT password FROM master_users WHERE username=
'%u' AND status = 'ok'
-- 

on destination server:


auth_master_user_separator=*

 passdb sql {
 args =
/usr/local/etc/dovecot-master.conf
 master = yes 
 pass = yes 
 } 


default_pass_scheme = CRYPT

password_query = SELECT password FROM
master_users WHERE username= '%u' AND status = 'ok'

I also tried on proxy:


password_query = SELECT NULL AS password, host, 'Y' AS nologin, 'Y' AS
nodelay, 'Y' AS nopassword, 'Y' AS proxy,'%u' as user ,'%u*pierre' as
destuser, '123' as pass FROM proxy WHERE domain = '%d' 

instead of


password_query = SELECT NULL AS password, host, 'Y' AS nologin, 'Y' AS
nodelay, 'Y' AS nopassword, 'Y' AS proxy,'%u' as user FROM proxy WHERE
domain = '%d' 

it did not work :(
