Hello Timo,
I've got some questions about dovecot-auth processes which I cannot answer just by reading the doc :
[ Note : my problem is that I often see
dovecot: pop3-login: Can't connect to auth server at default: Connection refused
and I'm looking for a way to tweak dovecot.conf parameters to allow more login <-> auth connections
]
I'm not sure I get the auth worker process concept right : is there a master dovecot-auth which listens to new incoming connections from login processes and fork/exec the real job of authenticating against the pass/userdbs to a child, called an auth worker ?
is it safe to increment the number of auth processes (the 'count' parameter in the auth block (auth_default { ...} for instance) ?
my understanding is that login processes communicate with auth processes through a unix type socket (named 'default') :
can I create a second auth block in dovecot.conf (for instance 'aut extra {...}') in addition to the existing 'auth default {...}' one ? would it create an second unix socket and thus allowing a heavier login processes load ?
what would be the difference between that and, say, changing the 'count' parameter to '2' in the 'auth default' section ?
thanks.
