I was going to ask how much space I should allocate for auth_cache_size - but decided to read the wiki first. Now I'll be more specific - Wiki says about 50 bytes per passdb, and up to 200 bytes for userdb - so my arithmetic says each combined entry needs 250 bytes budgeted. Assuming that's correct, I need some clarification. Let's start small. Assu...

Hello Is there a way to calculate this parameter for my site which has approx 4000 users authenticating thru NIS ? Thanks a lot

Hello, the dovecot-example.conf states: # Authentication cache size in kilobytes. 0 means it's disabled. # Note that bsdauth, PAM and vpopmail require cache_key to be set for caching # to be used. #auth_cache_size = 0 # Time to live in seconds for cached data. After this many seconds the cached # record is no longer used, *except* if the main database lookup returns # internal failure. We also try to handle password changes automatically: If # user's previous authentication was successful, but this one w...

So settings like auth_cache_size = 65536 auth_cache_ttl = 86400 auth_cache_negative_ttl = 600 are ignored/useless, and passwd-file auth lookups always results in file read operation?

Any way to minimize the number of sql statements that dovecot do? (and I tried adding userdb prefetch { } but number of sql calls are still the same) Am I doing something wrong or?

With auth_cache_size set to a value greater than zero, when our users change passwords their accounts stop working for a few minutes, because they are trying to log in with their new password, but Dovecot is comparing that against the cached old password. It would be nice if an option could be added so that if the log...

When you set auth_cache_size to a value greater than zero, it breaks the master password feature in Dovecot. It appears that during a cache hit, Dovecot attempts to query the userdb for use the master user's home directory and other settings, rather than querying for the userdb settings of the user that the master was try...

Hello, setting auth_cache_size to nonzero enables caching of authentication data. The cache hitrate may be logged by sending SIGUSR2 to dovecot/auth process. Is it possible that dovecot logs statistics on regular intervals ? ( like http://www.postfix.org/postconf.5.html#anvil_status_update_time ) Andreas -- Andreas Schulze In...

...ther with pam, using a pam module integrated with our SSO that is used from our webmail). I would like to disable password caching in my pam database (because 'passwords' provided by our SSO are single use tokens, so caching them has no benefit), but not in the ldap. As far as I know, auth_cache_size is the option to enable caching in all databases. But, is there any option I could use to disable it in a specific password database? -- Angel L.
