RE: File Transfer Problem

Hi All

I am running into problem in securing File Transfer from AS/400 to PC using client access.This is the exit program registered with QIBM_QTF_TRANSFER

*
      * Arrays for transfer string
      *
      * Data structure of parameter I#FLD
     d i#fld           ds          4171
     d  i#usr                  1     10
     d  i#app                 11     20
     d  i#rqs                 21     30
     d  i#tobj                31     40
     d  i#tlib                41     50
     d  i#tmbr                51     60
     d  i#tfmt                61     70
     d  i#tlen                71     75  0
     d  tfrrq                 76   4171
     d                                     dim(4096)
      *
     
     d reject          c                   const('0')
     d accept          c                   const('1')
      *
           d i#rtn           s              1
      * No specific parameters for message function call
      *
           c     *entry        plist
     c                   parm      o#rtn         i#rtn
     c                   parm                    i#fld
      *
     c     *like         define    i#rtn         o#rtn
      *
      * Default to reject requests
     c                   move      reject        o#rtn
      *
     c                   if        (i#rqs = 'SELECT') and
     c                             (i#usr = 'ITDRIZWN")
     c                              (I#TLIB    ANDEQ'RPGISCOOL')
     c                   move      accept        o#rtn
     c                   endif
      *
     c                   eval         *inlr=*on
     c                   return

But the above exit program doesn't work as any other user profile was able to transfer files to PC apart from ITDRIZWN in the program.We are on V4R4 and on TCP/IP so no need for router user profile as I understood.I don't want to tightly secure the database libraries by taking away their authorities by giving strict exclude which will avoid the problem.

What I am missing and how can I control.Is there anything to do with CA Express or any configurations in SubSystems?.

Thanks for any help,
