Hi Heiko, Sorry for using your private email address. :/ I managed to get this working using local_user changes by adding ldap user verification there:
local_user: debug_print = "R: local_user LDAP lookup for $local_part@$domain" driver = accept domains = +local_domains condition = CHECK_VIRTUAL_USER transport = dovecot_lmtp cannot_route_message = Unknown user Where CHECK_VIRTUAL_USER is: # Query that tests the existence of the user CHECK_VIRTUAL_USER = \ ${lookup ldap{user="cn=exim4,ou=dsa,dc=mydomain,dc=com" pass=PASS \ ldap:///dc=mydomain,dc=com?mail?sub?(&(objectClass=inetOrgPerson)(mail=$local_part@ $domain))}{$value}fail} Thanks again for all the support. You pointed me in the right direction. :) 2016-11-21 11:16 GMT+00:00 Heiko Schlittermann <h...@schlittermann.de>: > Hi, > > Heiko Schlittermann <h...@schlittermann.de> (Mo 21 Nov 2016 11:50:13 CET): > > a) Routing stage > > You need to interact with the user database dovecot uses. > > Either you access the user database directory (flat file, LDAP, > > whatever) or you use the ${readsocket…} feature of Exim to talk to > > dovecot. > > The readsocket trick doesn't seem to work anymore. > > Using > $ socat STDIO UNIX:/run/dovecot/auth-master > < VERSION 1 1 > < SPID 16290 > > VERSION 1 1 > > USER 42 hs12 service=imap > < USER 1 hs12 uid=500 gid=500 home=/var/vmail/home/h/hs12 > > (the spaces are tabs). > > But using Exim > > exim -be '${readsocket{/run/dovecot/auth-userdb}{VERSION\t1\t1\ > nUSER\t1\hs12\tservice=imap\n}}' > > does not work.
