[Mono-dev] UnixUserInfo issues in OpenBSD

[pablosantosluac at terra.es]

Reading your C code I see once more how powerful C# is... :P

This is what I get:

$ ./a.out tester
# checking return value 1; errno=13
User tester:
         pw_name=ÇEðÄ
À
 ¢
          pw_uid=752427404
          pw_gid=-809631572
        pw_gecos=(null)
          pw_dir=(null)
        pw_shell=UåSj


$ ./a.out pablo
# checking return value 1; errno=13
User pablo:
         pw_name=ÇEðÄ
À
 ¢
          pw_uid=656871820
          pw_gid=-809738964
        pw_gecos=(null)
          pw_dir=(null)
        pw_shell=UåSj


We're getting an errno in both cases...

OpenBSD is a cool beast! :P
