\fBauth_enumerate\fR
enumerates all of the available accounts\&.
\fBauth_enumerate\fR
repeatedly calls
\fBcallback_func\fR, once for each account\&.

After invoking
\fBcallback_func\fR
for the last account,
\fBauth_enumerate\fR
invokes
\fBcallback_func\fR
one more time with all parameters set to
NULL
or 0\&.
.PP
If
\fBauth_enumerate\fR
encounters an error it will terminate without calling
\fBcallback_func\fR
with all
NULL
or 0 parameters\&. This can be used to determine whether a partial list of accounts was received\&.

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