Re: [Dovecot] Auth_cache not working?

Aha ok!

I can see the cache hits and misses now: so that's fine.

But I will just keep using my imapproxy to reduce I/O.

Thanks Timo.

Cheers,

Jan

No. Dovecot can't affect how and when clients create new connections.
auth_cache only reduces number of SQL queries when authenticating. You
can determine if it works by adding auth_debug=yes and checking "Hit"
and "Miss" log lines.

[Dovecot] Auth_cache not working?

[Jan van den Berg]

Hi,

 

I have:

auth_cache_size = 4096

auth_cache_ttl = 3600

 

I use Thunderbird connecting to my Dovecot IMAP server 1.1rc1. I click
on five folders and close Thunderbird.

This is my log:

 

dovecot: Feb 27 17:26:56 Info: Dovecot v1.1.rc1 starting up

dovecot: Feb 27 17:26:56 Info: auth-worker(default): mysql: Connected to

In Outlook Express:

 

dovecot: Feb 27 17:27:38 Info: imap-login: Login: user=,
method=PLAIN, rip=10.4.32.70, lip=10.4.32.235

dovecot: Feb 27 17:27:51 Info: IMAP(roka-05): Disconnected: Logged out

Sort of the same thing: but more inconsistent. Sometimes I click five
folders and OE will have done 3 logins sometimes 2.

 

So new IMAP logins for (more or less) every click in Thunderbird and OE;
this is what auth_cache_size should solve right?

 

Am I applying the auth_cache_* variables wrong or is something else
wrong?

 

Cheers,

 

Jan
