FYI - with MySQL it's vauth_open_read not vauth_open.


Yes, sorry, the correct name is vauth_open_read with replica enabled and read access.
Just a memory problem (age starts to work :-) ).

I'm thinking of
submitting a patch to vpopmail to unify the call, so that it can be
published globally.  It would be nice if vauth_open would work no matter
what the backend auth mechanism...

That is what I was expecting for a while (as told here a lot of time ago), but probably priorities of development have been others (I do not blame them of course).

But, as different DB have different kind of calls (vauth_open would only work for read operation on one, while it would work for all the operations on the other) It could be enough simply adding a common #define for the routine opening the database (in read mode or the best equivalent mode).

So chkuser will simply call that define (better, will call that #define if that #define exists), simplifying any further operation.

Does authdaemon die if it loses its connection to MySQL?  If so why not
just run it under daemontools.  If not, perhaps it should...

No, authdaemon seems to be simply opening a connection when starting and then trying the same connection for all future operations. So, after MySQL has been stopped, that connection cannot work anymore.
