I am trying to figure out why a policy that was written on RHEL 6.0 doesn't work the same on RHEL 6.5.

I have a policy whose domain is vasd_t
 
I am using the userdomain.if interface call which is supposed to give the domain access to create directories in the home dir root with the user home directory type.
  userdom_home_filetrans_user_home_dir(vasd_t)

Which calls:
  files_home_filetrans($1, user_home_dir_t, dir)
Which calls:
  filetrans_pattern($1, home_root_t, $2, $3)
 
Which is defined as:
        allow $1 $2:dir rw_dir_perms;
        type_transition $1 $2:$4 $3;
 
I would expect this to allow me to create a new directory in /home which is of type home_root_t, but what I am seeing is that the new homedir is being created with the type of home_root_t and not user_home_dir_t as expected.
 
I have also tried not calling the interface methods and defining it by hand as:
 
allow vasd_t home_root_t:dir rw_dir_perms;
type_transition vasd_t home_root_t:dir user_home_dir_t;

I have also tried calling userdom_create_user_home_dirs(vasd_t)
 
sesearch shows:
 
$ sesearch -AC | grep 'allow vasd_t' | grep ': dir' | grep home_root_t
   allow vasd_t home_root_t : dir { ioctl read write getattr lock add_name remove_name search open } ;
 
The way the daemon works that is associated to the vasd_t domain is that it calls a script that does the actual creation of the homedir. I believe the problem lies in this fact that perhaps the script isn't being invoked in a way to give it proper creation rights.
 
Like I said this use to work in RHEL 6.0 but now I cannot seem to get it to work in 6.5. Any  help would be appreciated. I don't know what I am missing here.

You should only need.
userdom_home_filetrans_user_home_dir(vasd_t)

You need to look at your transition rules.

sesearch -T -s vasd_t -t home_root_t -c file
