NoCat and DES encryption

I currently have the nocatauth system setup with two boxes.  One is the gateway, the other is the authserv.  The authserv currently has the Mysql database on it.  It is working perfectly after a few hours of confusion (on my part).  However, I have a username/password list that I have imported into the database that actually has the passwords encrypted with DES (13 characters).  Obviously, NoCat uses MD5_Base64 encryption and isn't working with my list.  What I would like to know is the following:

1)  Is there a way to make NoCat use DES instead of MD5_Base64?

2)  If I cannot do #1, does anyone know if the TACACS option is a viable solution?

3)  Has anyone written a PHP script to enter username/password combos into a database like I have?

Any help is appreciated.  Thank you all in advance, this is a great product!
