Minor Bug: you nead a "break;" on the line after "retstat = ...",
otherwise you keep testing on a failed resource...

If so why not just run it under daemontools. If not, perhaps it should... I haven't looked at authdaemon/courier-imap v4 lately, but I dislike the mechanism somewhat because there's no way to get the TCPREMOTEIP info from the imap daemon to vpopmail, which I use to determine if I even need to update the relay table (I don't if it's in my permanently allowed subnet, or from my local webmail server...) which saves time on heavily loaded servers...

Can you post the change here so that those of us who want to look at
it
and test it can?
Yes, here are changes. I've already tried them and it works. Just
studying the name of calls it may be adapted to Postgres also (it should
be enough to use vauth_open() ).
In chkuser_settings.h enable
#define CHKUSER_ENABLE_VAUTH_OPEN
and add one of the following lines:
/* use this if you are using replicated MySQL, with read access */
#define CHKUSER_VAUTH_OPEN_CALL vauth_open
or
/* use this if you are using standalone MySQL, with readwrite access
*/
#define CHKUSER_VAUTH_OPEN_CALL vauth_open_update
In chkuser.c, just substitute the following lines:
#if defined CHKUSER_ENABLE_VAUTH_OPEN
if (db_already_open != 1) {
if (vauth_open () == 0) {
db_already_open == 1;
} else {
retstat = CHKUSER_ERR_AUTH_RESOURCE;
}
};
#endif
with:
#if defined CHKUSER_ENABLE_VAUTH_OPEN
if (db_already_open != 1) {
if (CHKUSER_VAUTH_OPEN_CALL () == 0) {
db_already_open == 1;
} else {
retstat = CHKUSER_ERR_AUTH_RESOURCE;
}
};
#endif
Any input/comment is welcome.
Another comment on side effects of restarting MySQL.
Courier auth daemon must be restarted, because it does not try to reopen
any MySQL connection.
It would be nice to have a simple perl script monitoring MySQL (an attach
every x minutes), and in case of problem:
- running
a script for shutting down Courier and other mail services
-
stopping/restarting MySQL
- running
a script for restarting all mail services
