Problems with adopting authority.

I have a program that tried to use system().  Now I am using QCAPCMD and 
having the same results.

The command I am passing is:
           cmd='CRTUSRPRF USRPRF('+userprefix+id400seq+') ' +
                         'PASSWORD(*NONE) ' +
                         'INLMNU(*SIGNOFF) ' +
                         'LMTCPB(*YES) ' +
                         'TEXT(FTP) ' +
                         'SPCAUT(*NONE) ' +
                         'LMTDEVSSN(*YES) ' +
                         'GRPPRF(' + USERPREFIX + ') ' +
                         'OWNER(*GRPPRF) ' +
                         'ACGCDE(FTP)';
where the USRPRF is GDI0000001 and GRPPRF is 'GDI'
The error I am getting is CPF9802 not authorized to the group profile.
DSPLY  ExceptionId 
DSPLY  CPF9802 
DSPLY  ExceptData 
DSPLY  GDI       QSYS      USRPRF
Dang, if it can run the CRTUSRPRF why can't it access the group?
