>Description:
      When calling setusercontext to the user, which have an 'umask=' entry in his login class in /etc/login.conf, some umasks are set incorrectly, E.g. when using "umask=407" (for incoming FTP not to store warez :) actually got d--xr-x--- instead of d-wxrwx--- permissions.
>How-To-Repeat:
      Add
test:umask=407:\
        :tc=default:
      in /etc/login.conf, call cap_mkdb /etc/login.conf and do
pw user add tmpuser -L test -m
       to create user.

simple program:
#include <stdio.h>
#include <unistd.h>
#include <sys/types.h>
#include <pwd.h>
#include <login_cap.h>

int main(int argc, char *argv[])
{
  struct passwd *pw;

  rmdir("/tmp/tmpdir");
  pw = getpwnam("tmpuser");
  setusercontext(NULL, pw, (uid_t)0,
    LOGIN_SETLOGIN|LOGIN_SETGROUP|LOGIN_SETPRIORITY|
    LOGIN_SETRESOURCES|LOGIN_SETUMASK);
  system("mkdir /tmp/tmpdir");
  system("ls -al /tmp/tmpdir");
}
       will show
total 4
d--xr-x---  2 root  wheel  512 26 &#1080;&#1102;&#1085; 23:32 .
drwxrwxrwt  8 root  wheel  512 26 &#1080;&#1102;&#1085; 23:32 ..
