Citrix ClearPassword (launch.ica)

while doing a pen-test I noticed after stealing launch.ica files from a users IE cache directory, they have a different ClearPassword= field. It appears of AutologonAllowed is set to ON this will be saved after using nFUSE to login to the citrix metaframe. These fields are as follows:
AutologonAllowed=ON
Username=test
Domain=\25A43DEFACEDCODE (16 bytes, hash) ClearPassword=D4239AF390DB09 (16 bytes, hash..) This obviously is an issue, the ClearPassword worries me, unfortunately I'm not a cipher kid so I'm not exactly sure what type of hash this is, or how it was created. I tried after researching how the password is kept in the APPSRV.INI file and tried to mimic the length but alas it did not work. If you have any information regarding what cipher this is or how its created please let me know so I can add this to my hackingcitrix.txt. Thanks

P.S: I tried to just use the launch ica but it tries to log in to the metaframe host itself and not the domain so the login attempt fails and the ***** is erased. This is why i'm in need of knowing how to get the password from this hash.
