NAME

       auth_enumerate - Obtain list of accounts

SYNOPSIS

       #include <courierauth.h>

       auth_enumerate(int (*callback_func) (const char *, uid_t, gid_t, const char *, const char *, const char *, void *),
                      void *callback_arg);

DESCRIPTION

       auth_enumerate enumerates all of the available accounts.  auth_enumerate repeatedly calls callback_func,
       once for each account.  callback_func receives the following arguments:

       •   Account name.

       •   Account's numeric userid.

       •   Account's numeric groupid.

       •   Account's home directory.

       •   Account's mailbox (if defined, may be NULL, which indicates the default mailbox location).

       •   Account's options string (if defined, may be NULL)

       •   callback_arg, verbatim.

       After invoking callback_func for the last account, auth_enumerate invokes callback_func one more time
       with all parameters set to NULL or 0.

       If auth_enumerate encounters an error it will terminate without calling callback_func with all NULL or 0
       parameters. This can be used to determine whether a partial list of accounts was received.

           Note

           Some back-end Courier authentication modules do not implement account enumeration, so this function
           may not be available in all configurations.
