Ok I'm looking in source code

there is:

copy8_3 (dta->dta_pat, slash);
This is I suppose the way to pass from longfilename to short
If I understand you not need to do something here if Pdomain is put to 1 by client

And at:
strncpy (dta->dta_name, slash, TOS_NAMELEN-1);
change by  
strncpy (dta->dta_name, slash, PATH_MAX-1); if Pdomain = 1;

It could looks something like this if I understand:
if (p->domain == DOM_TOS) copy8_3 (dta->dta_pat, slash);
....
if (p->domain == DOM_TOS) strncpy (dta->dta_name, slash, TOS_NAMELEN-1);
else strncpy (dta->dta_name, slash, PATH_MAX-1);
