[Serusers] xmlrpc calls

[zkeatts]

Jan,

 Thank you for your explanation, it has really cleared up a lot of my questions.  
I am confused on one point, where you said "location" should be the value that I am
using.  Are there a set number or only a specific few tables that will be accepted by
this call?  When I use location I get the XML reply

<value><string>AOR Not Found</string></value>

which is expected, because my "location" table is empty.  When I switch "subscriber" 
for "location" I get the following reply

<value><string>Table Not Found</string></value>

That is perplexing since we both know that suscbribers is there.  Looking at the library itself 
I have been able to determine that I will get this sort of reply when the system cannot
find the domain.

ul_rpc.c (lines 374 - 403)

  rpc_find_domain(&t, &d);
  if (d) {
     ...
  }else {
     rpc->fault(400, "Table Not Found");
  }

Why does the system find a domain for "location" but not for "subscriber"? E

Thank you for your patience so far,
