On one of my AIX 3.2.5 boxes I faced with the same problem. As I figured
out, seteuid() isn't work correctly, but setuid() does. If you have the
same problem with your Red Hat, in $(SRCDIR)/src/tools.c file look for the
following code part:

    if (setresuid(pwd->pw_uid, pwd->pw_uid, 0) < 0)
        debug(50, 1, "leave_suid: setresuid: %s\n", xstrerror());
    if (seteuid(pwd->pw_uid) < 0)
        debug(50, 1, "leave_suid: seteuid: %s\n", xstrerror());
    if (setuid(pwd->pw_uid) < 0)
        debug(50, 1, "leave_suid: setuid: %s\n", xstrerror());

I don't know which of the above functions are implemented in Red Hat to
change uid and gid. Maybe, you can try another instead of the preferred

I hope it helps,
