I'm very confused because it's not running. Here my details:

In chgsaslpasswd.c I defined as
#define UID 60
#define CMD "/usr/local/bin/sudo -u root /usr/local/sbin/saslpasswd2
(in sudoers is root defined as allowed all, I also tested this string
as a normal shell user and it works)

or
#define UID 60
#define CMD "/usr/local/sbin/saslpasswd2"

both is not working.

sasldb2.db is not working with
-rw-rw----  1 root  cyrus    24K  3 Nov 16:53 sasldb2.db

it's working only with -rw-rw--w- but the strange issue is that the
group cyrus has the members

acsvfbsd04# pw show group cyrus
cyrus:*:60:cyrus,www

and httpd is running as user www (and group www).

As which user does chgsaslpasswd running? The rights are
-rwxr-xr-x  1 root  wheel   3,3K  3 Nov 17:30 chgsaslpasswd (I will
set the rights discribed in the Readme later).

PS: I'm not a c programmer but what does chgsaslpasswd? I see only
some definitions (at the begin) and some compares (at the end).

Regards,
Martin
