ACL Script help

Hello, I am needing some help with an ACL on a custom table. I have a UI action that is ran from the incident table that shows the u_temp_credential table and writes some fields to it. Then ONLY the logged in user should be able to see the u_temp_credential table to see the username that was created just for them. When I impersonate the user I get a security constraints error. I appreciate all of your help from the start, as I'm learning ACL's - they remind me of Windows server group policies, ugh!

For an ACL, is a record type the same as a field on a form?

answer = ifScript();

function ifScript(){

  //gs.log('ACL: sys_class_name is ' + current.u_parent.sys_class_name);

  if(current.u_parent.sys_class_name == 'sc_req_item'){

  //gs.log('ACL: table is sc_req_item');

  if(current.u_parent.u_requested_for == gs.getUserID() || current.u_parent.opened_by == gs.getUserID()){

  return true;

  }

  } else if(current.u_parent.sys_class_name == 'incident') {

  //gs.log('ACL: table is incident');

  if(current.u_parent.caller_id == gs.getUserID()){

  return true;

  }

  }

  return false;

}

You need two read ACLs...


1. Table level (u_temp_credential.)

2. Record level (u_temp_credential.*)

To put security on individual fields, then you need to put the appropriate type of ACL on the field (u_temp_credential.u_password).



Type should always be Record (for what you are doing).


Operation should determine what they can do (Create, Read, Write, Delete)



If the table was created and a role was associated with it (typical action) and you over-wrote the original read table ACL, then you will want to remove the role associated as the ACL requires the script to be true, the user to have the role, and the condition to be true.



To make this easier (now that I have more time), you can do this all using the condition builder instead of writing a script (my example is based on the incident table)

For Read and create operations?


If the records are being created from the UI Action without issue, then just read.

But they should not be able to access the password... which will be my next feat.


Access meaning; view or edit? That would be a similar ACL, but you would select the specific field from the second field on the Name string.

When I set name = temp_cred.* for role=itil; I get security constraints error on the entire table, they can't see the list view at all.



Gah!
