hi
i am the postfix+dovecot.for example,there are three servers:
server 1 for postfix
server 2 for dovecot
server 3 for auth server
how could i let the dovecot(2.29) authenticated by the other servers?
i config the postfix auth-type to dovecot.how could i config the
dovecot authenticated by the server 3 with tcp/ip socket?or is there are any
samples?i have found in http://wiki2.dovecot.org/.
*at first i try to use memcached ,these are the configure:*
*./dovecot-dict-auth.conf.ext*
uri = memcached:host=172.24.140.252:port=12000
password_key = dovecot/passdb/%u
user_key = dovecot/userdb/%u
value_format = json
iterate_disable = yes
default_pass_scheme = plain
* ./10-auth.conf*
auth_mechanisms = plain login
!include auth-dict.conf.ext
*./auth-dict.conf.ext*
passdb {
driver = dict
args =
/usr/local/dovecot/etc/dovecot/dovecot-dict-auth.conf.ext
}
userdb {
driver = prefetch
#args = /etc/dovecot/dovecot-dict-auth.conf.ext
}
*in memcached i put some data in：*set dovecot/passdb/test@test.com 0 0 103 {'uid':'123','gid':'123','home':'/home/username','username':'test@test.com','password':'test@test.com'} STORED set dovecot/passdb/test 0 0 103 {'uid':'123','gid':'123','home':'/home/username','username':'test@test.com','password':'test@test.com'} STORED set test 0 0 103 {'uid':'123','gid':'123','home':'/home/username','username':'test@test.com','password':'test@test.com'} STORED set test@test.com 0 0 103 {'uid':'123','gid':'123','home':'/home/username','username':'test@test.com','password':'test@test.com'} STORED
i reload dovecot and postfix.postfix connect to dovect is ok!i openthe debug log .the memcached tell that it has received a connection.and the
dovecot also said has connect to the memcached ,but after 30s,the connect to
the memcached auto broken by out of time.here some logs:

dict(965eb72c92a549dd,192.168.3.29): Lookup failed
i don't know why it happened.and why it look up key with prefix
"shared/".until now i found that the key is password
"965eb72c92a549dd"(password is the same as username before).what will
happened if there two people with the same password.it seams that i should
use the userdb!
is someone could give me a sample?what could i do if there has two or
more memcached servers?so ,i think of that if there has some config to
connect to the tcp socket server.and the server implement by java or any
other language by the developer itself.
thank you for you help!
