Hello,
I'm trying to configure dovecot (2.0.13) to cache user and pass dbs. This a mail server whose purpose is only to deliver messages through dovecot lda. My users are in a ldap server.
So I have configure auth_cache_size (with 20MB) and auth_cache_ttl (with 1 day). I have checked that caching is being done, and it is. If a send a message to a user, dovecot looks for it in my ldap server. If then I send another, then it uses cache information.
The problem I'm having is that if I have no activity in the server, dovecot stops its auth process and when another message is received, it restarted it, but with an empty cache.
This is the auth log for the first message:Mar 22 10:29:41 lynx10 dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Mar 22 10:29:41 lynx10 dovecot: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so Mar 22 10:29:41 lynx10 dovecot: auth: Debug: master in: USER#0111#011amateo#011service=lda Mar 22 10:29:41 lynx10 dovecot: auth: Debug: prefetch(amateo): passdb didn't return userdb entries, trying the next userdb Mar 22 10:29:41 lynx10 dovecot: auth: Debug: userdb-cache(amateo): miss Mar 22 10:29:41 lynx10 dovecot: auth: Debug: ldap(amateo): user search: <search base and filter> fields=irisMailbox,homeDirectory,uidNumber,gidNumber Mar 22 10:29:41 lynx10 dovecot: auth: Debug: ldap(amateo): result: uidNumber(uid)=XXXXX gidNumber(gid)=XXX homeDirectory(home)=XXXXXXXXXX Mar 22 10:29:41 lynx10 dovecot: auth: Debug: master out: USER#0111#011amateo#011uid=XXXXXX#011gid=XXX#011home=XXXXXXXXXXXX
And this is the second one, just after a few minutes:Mar 22 10:41:03 lynx10 dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Mar 22 10:41:03 lynx10 dovecot: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so Mar 22 10:41:03 lynx10 dovecot: auth: Debug: master in: USER#0111#011amateo#011service=lda Mar 22 10:41:03 lynx10 dovecot: auth: Debug: prefetch(amateo): passdb didn't return userdb entries, trying the next userdb Mar 22 10:41:03 lynx10 dovecot: auth: Debug: userdb-cache(amateo): miss Mar 22 10:41:03 lynx10 dovecot: auth: Debug: ldap(amateo): user search: <search base and filter> fields=irisMailbox,homeDirectory,uidNumber,gidNumber Mar 22 10:41:03 lynx10 dovecot: auth: Debug: ldap(amateo): result: uidNumber(uid)=XXXXX gidNumber(gid)=XXX homeDirectory(home)=XXXXXXXXXXX Mar 22 10:41:03 lynx10 dovecot: auth: Debug: master out: USER#0111#011amateo#011uid=XXXXX#011gid=XXX#011home=XXXXXXXXXX
