Hi Gasper,

I have been doing some testes with R.3.14.9-pre1 and gateway. I have no

problems with alarm acknowledgments trough gateway.


Great - thanks.


But I have another problem related to access security. Access file

looks like this:

HAG(GATEWAYS) { CSL85 }

ASG(DEFAULT) {
 RULE(1,READ) {
   HAG(GATEWAYS)   }
}


This works (I can read from CSL85) with R.3.14.8.2 but I don't have read

access from CSL85 if I build gateway with R.3.14.9-pre1 (it is the same

also with R2.14.8 from CVS from 17.11). I saw in release notes that

something was changed in access security but I am unsure what should I

change in this access file to have read access again with R.3.14.9-pre1.

This access file is used on gateway not on the ioc. Ioc has no access

security switched on.



That is a bug I inadvertently introduced during my changes to asLib,

which I discovered while running Marty Kraimer's test suite and fixed a

few days ago. The following diff shows the change you need, in src/as:

Please let me know if this does /not/ fix the problem.

Thanks again,
